Listen to article

Xiaomi has officially launched its online store in the Philippines Google tests 5GB storage limit for new accounts without phone number verification Sony unveils Xperia 1 VIII DJI announces Osmo Pocket 4P at Cannes Sony unveils Alpha 7R VI

Found this at the PC Express website:

“The DI-LB604 is the newest addition to our range of routers that includes the industry’s latest technology. It provides all the functionality needed to establish a reliable high-speed Internet link while at the same time protects past investments,” said Mr George Wong, Marketing Director of D-Link International Pte Ltd.

The Load-Balancing Router with features 2 WAN ports for load-balancing and a fast-acting fail-over mechanism for dropped Internet connections. 4 Ethernet ports provide wired connections to up to 4 computers. Thus, users can set up a high-performance network that offers the fastest and most reliable speeds, without sacrificing their past investments.

Advanced Network ProtectionWith SPI and NAT firewall with DOS attack protection, the DI-LB604 provides secure and reliable network connections. System logging, ACL and VPN pass-through protects the network against outside threats.

Easy Management and SetupThe DI-LB604 can be easily configured using its web-based management interface.

The DI-LB604 Link Load-Balancing Router will be available soon at all PC Express branches.

If from what I understand here is right, this means you can hook up two DSL accounts and combine them into one router and get an effective connection rate equivalent to the sum of both broadband connection.

So, I have an existing PLDT myDSL at 1.2Mbps and another Smart Bro account at 386Kbps. If I use the DLink DI-LB604 router, I could have 1.586Mbps connection speed on my network. If one is down, the other is still hooked up. Cool! I want one!

Im using Lusca for windows,so far oks namn hiwalay ang browsing for WAN1 (Firefox-independent yun paglagay ng proxy) tapos yun sa gaming direct to WAN2.

Jason · 13 years ago

HELP naman po. Pede po ba magamit sabay ang 2 ISP ko sa dual wan ang isa PLDT dsl static at yung isa sky broadband dynamic. Pano po ba ito iconfigure? static yung isa dynamic? patulong naman po.

where i can buy the load balancer and who can install that coz i need that in my shop? thanks

chris · 14 years ago

san po ba nakakabili ng load balancer kasi dito sa batangas wala pa ko mabilihan and sino ba pwede mag install nun kasi kelangan ko din sa shop. thanks poh

@trebor

i have more than 50 PC’s under my pfsense dual-WAN router/server. my server is just a low-profile old CPU;
-Pentium 4 2.4ghz
-512mb RAM
-512MB M2/memorycard via USB (serves as my hardrive with pfsense installed)
-3 ethernet LAN card (2×10/100Mbps, 1xGigabit LAN card)

ISPs:
-Globe 3Mbps Taipan package 8k/month (using it for 5yrs now)
-PLDT DSL business plan 3Mbps (using it more than 5yrs now)

exploited_2008 · 15 years ago

Yup I agree with cybercon. Meron kami sa office F5 link controller 3 ISP ang naka load balance. For example lahat ng VoIP traffic para sa isang ISP (Eastern), tapos lahat ng site na may video’s like youtube sa another ISP (PLDT), then the rest of other websites sa 3rd ISP (Globe). For example nag down yung Eastern, manually ililipat yung traffic papuntang Globe or PLDT.

If you don’t like D-Link load balancer here comes the Cisco linksys RV042 router with Dual LAN / Load Balancer, 4 port VPN and SPI firewall.

thanks yuga.

trebor · 15 years ago

@Cybercon

Ilang workstation ang nasa office nyo? Kasi i will also be using load balancing dito sa office.

Miky · 15 years ago

It does load balance with the new firmware. Set the port Options of WAN and set Connection health check so that it can detect when the connection is broken. E.G, ping the main gateway of each ISP.

Re: load balancing router..

Mga bro/sis,

Hanap ako ng advice..mayron akong existing 3.5 mbps na pldt connection sa internet business ko..im planning na magdag2xg ako additional lines galing parin sa pldt at 3.5 mbps..pwede ba na isang pc serves as 1 server pc for 30 to 35 units pc by using load balancing router?..hindi ba hihina ang speed dahil sa isang pc lang na server?..magkano kaya yang load balancer?..my binibenta ba kau sa davao?..thanks..jerome of Kidapawan City

Ceasar · 14 years ago

sir jerome gud afternoon may offer poh ako sayo internet connection..mabilis poh to.. pwede poh ako mag semo sayp if gusto mo.. just contact me @ 0948*******.. tga kabacan poh ako..

cybercon · 16 years ago

Load Balancing is simply a network traffic manageability. Allowing you to use two ISP/WAN into single LAN/internal network to balance your network port traffic and at the same time acts as a fail-over.

Hindi magiging additive speed nyo if for example meron kang 1Mbps/pldt & 1Mbps/globebroadband.

You will set a rule to manage the network traffic from your ports assignments to which ever ISP it will go. you have to config your router properly.

Halimbawa, yung port 80(HTTP) at port 110/25(Pop3/SMTP) ay padadaanin nyo sa PLDT. Tapos yung port 21(FTP) naman ay padadaanin nyo sa GLOBE. In this order, makakaluwag sa traffic yung browsing/emailing at downloading(FTP) dahil magkaiba sila ng dinadaanan. kapag nag download ka via FTP, hindi affected si HTTP/POP3/SMTP dahil magkaiba ng ISP ang dadaanna nila.

At kapag nag-offline ang isa sa kanila, mag fail-over ito sa kabilang ISP, dyan medyo babagal kase shared sila sa lahat ng net-traffic sa iisang ISP.

I use the same scenario on pfSense, and it benefits me a lot on this setup for our office.

joelz · 16 years ago

hmmm… mga bro… load balancing router ba… i tried D-Link dual WAN… d tlga gmgana jn ng sabay. prang failover lng.. when 1 line is down automatic na gagana ung isa. i switch to EDIMAX…un ska ko ngamit ng sabay ang 2 smartbro. d cya nag a-add ng bandwidth. prang hahatiin lng nilang 2 ang traffic. pro mrmdaman mo na improve ung browsing at ung u-tube ko halos d nagbu-buffer. edimax nlng kau.. wlang inaayawan na connection. whether wireless man cya o wired lines.. u can use both of them at the same time…

mspre · 16 years ago

ang alam ko eh halimbawa traffic n ung WAN1 eh saka mg-enable WAN2…hindi cla ngcocombine ng speed…pero once n hindi n kaya ng WAN1 ang traffic eh mgactivate n ang WAN2 to reduce traffic..

tazzky · 16 years ago

Best way to do is to subscribe at one internet provider with two lines then combine. I mean like in SmartBro, get 2 999 plans and hook them up on your load balancing router. Well probably it won’t reach the 2Mbps mark but it’ll certainly be stable @ 1Mbps or more. :D

tubol · 17 years ago

Mga bobo…

You people who are saying it doesn’t load balance… you probably tried to download from a single FTP or website. Which is a single connection. A single connection to your computer through the router can only utilize 1 of the wan ports… but start multiple downloads and your in business.

Try downloading through torrent or using a download accelerator such as IDM or DAP that will use multiple connection.

[quote]Sir need help pwede ba ito e setup 2 dsl line din distributed to 40 pc 20 for dsl line 1 din the others 20 to dsl line 2 pwede ba ganito ung setup kasi i need to add new dsl line. kasi medyo mbgal na para segragation ang gagawin ko many tnx hope matulungan nyo ako ty [/quote]

————————————-
rybaxs answers:

Yes, its possible…
I will show you the set-up

dslA -> switchA -> 20PC
dslB -> switchB -> 20PC

Advantages: speed up the line, dedicated

DisAdvntges: the problem with this is that when A/B dsl disconnect 20PC at A/B will be disconnected.

The speed from A and B are different, that’s why we have 2WAN Router or 2WAN Router with WIFI

————————————–

dslA & dslB -> 2WANRouter -> switchA -> 40PC

dslA/B -> 2WRoutrw Wifi -> wifi PC | swithA -> PC

You can configure the 2WAN Router

There are types of Router that you can group numbers of IP. It’s a best way for 2WANRouter to be configure static IP on each terminal due to IP collusion.

REMEMBER:

dslA = 1.5 MBpS
dslB = 2 MBpS

2WANRouter with dslA&B = ?

you’re a stupid person if the answer is 3.5MBpS

private DSL speed will be divided..
Try the commercial type DSL. Ask the burst speed.

example:

dslA private 1MBps fluctuates .2-.8MBps
.1MBps per PC if you have 10PC

dslB commercial 1MBps fluctuates .5-1.2MBps burst
1MBps per PC if you have 10PC
because they will give you a higher bandwidth.

What is bandwidth? it is like a bridge
if your bridge have 2lanes, think of it how traffic your net connection.
if you have 30lanes bridged. woahh.. i think you can put a cafeteria at the center of the bridge. hehehe.. in layman’s term

wew…

Load balancing ginamit ko na din to with latest firmware, pldt 5mbps and globe 5mbps dapat 10mbps diba tulad ng mga nauna nyong sinasabi, pero nothing happen but it slow down my connection from 5mbps ng pldt naging 1mbps dahil nag kakaroon ng conflict sa dns. at laging namamatay ang connection ng globe . hindi sila pwedeng pagsabayin. one at a time lang talaga para ma maximize mo ang dsl speed mo. i suggest not to buy this product it’s wasting your time to configure and money for nothing.

ang hina nyo talaga!!!! ganito yan gumagamit ako ng Bayantel At SMart Bro ngaun naka assign sa WAN 1 ung Bayantel at WAN2 ung SamrtBro hinde pwede sila mag combine ng speed kc magkaiba anf DNS nila anong tingin nyo sa dalawa TUBO ng TUBIG isa sa POSO at isa sa MAYNILA kaya paginamit nyo ung dapat naka-enable ung WAN1 at BACKUP lang ung WAN2 magkakaconflict talaga mag sabay sila ano ba kayo mga SIRANICHIAN yata kau alam nyo lang yata ay mag DOTA at mag cabal ayusin nyo mga network nyo heheheh

Ali · 17 years ago

Hi, if you want to load balancing, use pfsense. its a free router with firewall capabilites. all you need one extra computer if you have. install the software and enable the load balancing on it. but keep in mind load balancing doesnt mean that you will be able to combine the speed of two seperate wan lines.
thanks

mga dude gamit din ako ng dlink-lb604 sa computer shop nung una asar na asar na ko kc hindi ko sla pedeng pagsabayin…hindi cla ngcombine ng speed..pldt mydsl (3.2mbps) At globe(2mbps) ngkaproblema pa ko ng pinagsabay ko cla, nung dsl p lang ok connection minsan lng disconnected sa pldt (pldc) heheheh. ang nakastatic ung pldt at naka dhcp ang globe naging ok sya pero hindi ng combine. load balancing lng nga(traffic lng ang ginagawa nila). disable ko n lng ung load balancing para magamit ko ung globe as backup and static lahat ng computer and dns nila ung gateway din. kong sakaling mgdown ang pldt!! try ko disconnect ung pldt nag-up ung globe mas ok n ko dun.. kesa mgalit mga players ko.

douglas donoghue · 18 years ago

I have this router installed in Tacloban, Leyte but have not been able to get it running in any reasonable fashion. It does not perform at rated speeds on a single provider nor balance anything. It is hooked to Globe and Bayantel

rybaxs · 18 years ago

“So, I have an existing PLDT myDSL at 1.2Mbps and another Smart Bro account at 386Kbps.”

That’s totally wrong..
You’ll just end up with 1.2Mbps

ninetails · 18 years ago

flash it with the latest firmware m0r0ns.

moot · 19 years ago

I think it just load balances but can’t do the additive bandwidth. It sounds difficult given the constraints of the TCP/IP protocol.

bluenux · 19 years ago

mr or mrs aki, i told you that D-Link DI-LB604 is fake.

Aki · 19 years ago

So, I have an existing PLDT myDSL at 1.2Mbps and another Smart Bro account at 386Kbps. If I use the DLink DI-LB604 router, I could have 1.586Mbps connection speed on my network. If one is down, the other is still hooked up. Cool! I want one

how do you configure two connection in 1?…

can u tell me pls T_T

bluenux · 19 years ago

D-Link DI-LB604 is fake, no automatic backup if one connection fails, you have to manually remove the other wan connection enable to regain the other connection.

Jess · 19 years ago

Has anyone used it? Also, are there any other company that provides similar routers?

Dave Starr · 20 years ago

I’m happy to see this device released and being publicized. Mish’s comment that there might be a better way with a dedicated server/network controller are fine, but it’s a network engineering project that the average blogger/small-time Internet business owner is not likely to have the skill set or time to implement. The D-Link solution is “plug and play”, so great for its intended market.

The issue is that for years and years we’ve all been operating “single string” … our business lives or dies based on one ISP. All ISPs will fail someday. The time has come, if we want to change a hobby activity into a sound business is develop ways to work around failures and D-Link’s offering is a great step forward.

Due to the way HTTP and the ‘Net in general works there is another advantage in load sharing. Most of the time spent waiting for a page to load is not caused by the raw speed of the connection or even the server serving the page. It’s caused by latency in all the other points along the network that packets have to transit. So 2 separate 265 kbps DSL connections could work out to be faster overall than 1 single 512 kbps “pipe” for example … because when one network drops to zero throughput due to some congestion, the other side may still be delivering packets. Alternating between all-half-all-half-all may add up to more total bits per hour than all-zero-all-zero-all.

Anyway, something to consider.

mish · 20 years ago

I’m often leery of “appliances” like this… often turning out non-secure, feature-locked, and horribly broken down the line.

IMO you’re still better off with an old Pentium I class machine (or even lower) with 3 NICs… WAN1, WAN2, LAN, (or the optional 4th NIC for WLAN) doing all the goodies: loadbalancing, failover (CARP), auth, packet filtering (or “SPI” in the ad’s corpspeak), NAT, etc. Total Cost: laughable.

All this with OpenBSD and pf. Or if you’re a Linux guy, I’m pretty sure it’s also possible but I’m not familiar with the penguin-ish approach
