Handling 3 WAN connections with linksys router.

    I'd like to setup a network that has 3 WAN circuits, each of which are backups for the others. E.G. Wan1 and Wan2 could be connected to a dual WAN router (like the rv042) and I could configure that router to use one WAN as a primary and the other as a backup. I could connect the third WAN to another router and connect that second router to one of the lan ports on the first, but I'm not sure how to setup the first router so that it uses that connection as a backup to the 2 WAN ports. Anybody have any ideas?

    I can think of two possible approaches to this:

    1) Put a route on the first router for default addresses and pointing to the inside address of the second router but with a higher metric attached to it. So then router 1 would only use it if both of it's other two routes were down.

    2) Use 2 dual wan routers and have one port of the first one connect to the inside port of the second which would have two real WAN addresses. You'd simply need a different inside subnet for connecting the two routers. (You might run into some NAT issues with this configuration, however).

    Sounds like good advice to me. I actually have nothing to add, I'm just posting a reply so it's easier for me to search for and find this post in the future! Nice 1st post dethomas143! Welcome to LinksysInfo! :thumb:
