Has anyone here ever setup a GRE tunnel between a snapgear firewall and Cisco Router? The Snapgear manual implies that it can be done, but doesn't give any examples.
What is confusing me is that a Cisco expects an ip address / subnet for the tunnel endpoint as well tunnel source and destination ip addresses. Where as the Snapgear is asking for a remote ip and a local ip (from the LAN address range according to the manual).
