Re: [44net] Dynamic IP Gateway problem.

You should describe the network setup in a graphically. I also see several issues unless your setup is fundamentally different: - if this is an iptables firewall for a host reachable directly via public IP, the host will be completely exposed (by excepting all protocol 4 packages). - the route 44.0.0.0/8 via tunl0 should always point to the UCSD router, e.g. "ip route add 44/8 dev tunl0 via 169.228.66.251 onlink table 44 I have published a HowTo http://marc.storck.lu/blog/2013/08/howto-setup-an-amprnet-gateway-on-linux/ which describes how to setup the IPIP tunnel server. Configuration element for NATted IPIP tunnel servers is yet missing, but I'm working on it. 73 de Marc Quoting sp2lob(a)tlen.pl:
