If anybody out there could help me set up the following scenario that would really be appreciated, here it is:
Main site: PIX>>Internet router>>ISP 1 and ISP 2
Remotes: PIX>>Internet router>>ISP 1 and ISP 2
Configs: IPSEC between PIX'S
The idea is to get GRE tunnels and to get redundancy if one of the ISP lines ever come down; also there is an inside router that we could use to build the tunnels or I was wondering if it makes more sense to build the tunnel interfaces on the outside routers how would it work.
