I assume you're referring to IP encapsulation according to RFC 2003 (with IP protocol number 4 in
the outer IP header). m0n0wall does not support this kind of tunnel (nor GRE tunnels, for that
matter) - only IPsec with IKE.

If you intend to use a separate device/router behind your m0n0wall to decapsulate the IP-encap
packets, you need a 1:1 NAT rule and a separate public WAN IP address to terminate the tunnel, as
m0n0wall does not allow for "inbound NAT" rules on arbitrary (i.e. non-TCP/UDP) IP protocols.

m0n0wall does not support any dynamic routing protocols, but I assume this would be run inside the
tunnel (with a RIP daemon running on the device that terminates the IP-encap tunnel on your end), in
which case it should work once you have the 1:1 NAT properly set up.
