| This isn't quite working. tcpdumping the gateways external port, I | can see the ICMP Echo Request makes it out and an ICMP Echo Reply | comes back, but it never make it into the LAN.
The packets on the external interface have the IP address of that interface. So oubound NATing is working. I'm not sure where in the firewall the return packets are being lost.
