Hi Fellas, I'm having some troubles since a year ago trying to connect vpn tunnels site to site with cisco 1841 routers with security features and watchguard firebox x750e firewall.
I have point to point leased lines or frame relay links between my Main site and the branch offices and I really need to maintain the operativity when this services are down. I thought having some kind of VPN tunnels as backup links but I've tried so hard connecting the 1841 and my watchguard with no success. I hope you can give me some ideas, commands or anything helpful to acomplish this very important task to my business.
I am attaching the network topology
