I'm trying to come up with a solution and need to see if anyone has any pointers or advice they would be willing to share. Basically what we have is our main Internet connection is a metro ethernet circuit to our ISP. Our ISP has also provided us with a T1 to serve as a redundant connection in case the metro ethernet circuit goes down. Currently, I am using 2 routers (one for the metro ethernet and one for the T1) but I cannot figure out what would be the best path get failover functioning. I have 2 ethernet interfaces on both of the routers so I was thinking that I could not use both IP blocks that the ISP provided me and setup HSRP using one of the blocks and put static routes in place for the other blokc which our web servers are currently natted to. I don't really think that will work unless I setup some sort of translation on the router which seems that it would interfere with the NAT we are doing on the PIX. I also theorized that I could setup a seperate 'private' network that is behind the routers and in front of the PIX firewalls ans utilize HSRP there but then I don't quite know how to setup the routing plus there would be issues with folks coming in via VPN. Hopefully someone has some ideas that or links that can help me out here. Thanks.
I have this problem too.
