Adsl Fail over / Load Balancing

[Scorpioman86]

Hi Guys,

I would like to find out if it is possible to get an adsl router that has two wan connections ?
both the connections should be for adsl and not adsl plus 3g, i would like to have a setup whereby if one line fails the other one can take over, or if both of them can work concurrently.

this will be for a new setup at an office with around 80 users and 120 devices.

Any advice will be appreciated.

regards,

P

You can implement this using a routerboard from Mikrotik.

You can also get two separate routers and set up your routing manually. This depends on your set up though, if you have a linux firewall set up you can do this quite easily. I am running two separate routers at our office using this method.

Google Results, first entry, 3rd post in response to thread (in a 3 post thread):

That should push you in the correct direction. However, it may be cheaper just to have a linux box/firewall (ipcop) and 2 routers

Also just remember that if your exchange fails, your lines fail (both of them). So you need to log a special request with Telkom to have the 2nd ADSL line installed at a different exchange

Could build yourself a Router that basically does this for you using the Astaro Home Edition (free if you fall within the terms and conditions that is).

Then have two modems on two network cards and bob's your uncle.

Hi there,
This site has a comparison of some Dual Wan routers available in RSA.
I am not sure that Xincom mentioned in the thread is still in business.
The MikroTik is also a good solution but is not going to be as plug and play as a dual WAN router.

As you can see, there are any number of ways to do this; with the RB route likely being the most flexible ...at the likely cost of also being most likely to drive you insane to set up. That said, you also get load balancing product like the TP-Link R470T+, which you would then pair with single port modem/routers setup in bridge mode to handle the actual adsl connection. Which, while giving you three boxen needing power, also gives your precious network router a level of abstraction from the vagaries of lightning-induced surges coming down the phone lines.
