    I have 2 different broadband connections and 2 WRT54Gs. I'd like to somehow connect/configure the WRT54Gs so that if one of the broadband link fails traffic will automatically be routed through the other router. Any way to do this?

    i think that vlans would do this. you are going to need a firmware like dd-wrt or alchemy for this. i am not sure if the offical linksys firmware has this.

    I think OSLR http://www.olsr.org/index.cgi?action=adhoc might be a better fit. (not that I know much about it). OpenWRT and DD-WRT could both accomodate the oslrd ipkg packagehttp://tracker.openwrt.org/packages/list.php?name=olsrd. One of Sveasoft's future releases will also have OSLR added within the base firmware. If you are looking for something more out of the box, Freifunk-Firmware is an OpenWRT flavor with a full implementation of oslrd added into the base firmware. As jagboy said, you could try VLANs but I can't see how it would be easily done. Fault detection or failover is something others have asked for, but I have not seen a solid solution. It is possible to configure multiple WAN type ports and using iptables, but the challenge is having a dynamic default gatway (meaning detecting and changing it on the fly). You also have the limitation of hardware support for VLAN only for routers up to G V2.2 or GS V1.1(AFAIK).

    Thanks for the tips. It sounds like I just just use the rv042 instead. It seems to have pretty good support for failover.
