I'm too lazy to type all that stuff in myself. There is a nice
tool at http://linux-firewall-tools.com/linux/firewall/index.html that
will generate just about what you want for the non-CIPE interfaces
(be sure to mention the UDP port for the CIPE packets on the
external interface in what you want to allow).
If you don't mind the tunnel being completely open you can paste
in something like:
ipchains -A input -i cipcb0 -j ACCEPT
ipchains -A output -i cipcb0 -j ACCEPT
ipchains -A forward -i cipcb0 -j ACCEPT
somewhere near the top.
