My server is currently connected via ADSL telkom line. I have a Vodafone modem that connect to 3G via USB as well. What I would like to achieve, is to automatically connect via the 3g modem when the ADSL fails.
Any one got any ideas on how to achieve this. (it obviously needs to disconnect after ADSL is back up again as well).

Thanks!

There are a few options out there. Billion have a product that will do that for you (I just can't recall if the failover/back was completely seemless). Draytek also make a similar router. There is also a more corporate orientated solution by Strattice called Wipod.
 
The Billion 7300GX, 7402GXL and 7402GX provide auto-failover and auto-fallback. This works really well when the ADSL line goes down and when it comes back up. The transition is completely seamless.
 
Thanks Guys...and at around R1500 a pop its a good solution...will definately order one...:cool:

Good to know. When the 7300GX first came out the failover/back was not automatic, but I guess they fixed that in a subsequent firmware release.
 
Looks like it:
The BiPAC 7300GX is equipped with a built-in 4-port full-duplex 10/100 Switch so you can connect wired-Ethernet devices together. Directly connect up to four PCs or attach more hubs and switches to create a larger network as needed. Use the integrated Router function to share a blistering ADSL2+ or 3G-based Internet connection (requires a 3G data card, available separately), with automatic fail-over*4 to ensure an always-on Internet connection in
the event that one of your Internet services fails.

So where is the fine print that goes with the *
 
No, these are not power failures. I use the "Fastest" Telkom ADSL with the speed reduced to 1Mbit/s in order to improve stability. Yet, during the course of the day, I would lose the connection for a few seconds, roughly twenty to fifty times (some days are worse than others). During those periods both the DSL and Internet lights on my router are off. After a short period of time, say 10 to 15s, the DSL light comes back on and a few seconds later the Internet light.

During normal surfing this is not a big issue, a webpage may perhaps not open at the first attempt.

However, if you use the Internet for trading currencies or futures contracts, this does become a problem.

I am currently looking at other options in order to avoid this problem. Calling Telkom and asking them to “Flush the line/recreate the service” has helped to some degree.
