Hi List, I work for a small company and we are about to provision a wireless internet connection from a local ISP. We also have a backup DSL connection sourced from a large Telco. What I'd like to know is if there's any information out there on setting up our DSL connection so that the router will automatically bring it up and make it the default gateway if our wireless link goes down.
The router box is running Woody, custom 2.4.18 kernel, using Netfilter/iptables for a firewall. It's also running squid, apt-proxy and ipac-ng for network accounting. At the moment it's got two NICs in it, one for our internet connection and one for the LAN. I'm assuming I put another NIC in it, connect the wireless and the DSL, and configure the cards accordingly. Then I need to find a way to monitor the wireless connection so that the redundant connection is used when neccessary. Has somebody already written some software that does this? Or am I likely to have to do it myself? I'm thinking it's not going to be too tough to write a shell script to do it but I'd rather go with a proven solution than do my own coding and testing if possible. TIA for any help on this. Regards, Lucas
