I have two ethernet interfaces. Internally I have a 192.168.1.0/24 network, and NAT from the LAN works as expected. I put a modem on the system and configured mgetty+pppd for dialin. I am using proxy arp to make it appear that the dialed in user is local to that LAN segment. Locally this works properly. The weird thing is that I cannot successfully ping hosts on the Internet from the machine I am dialed in on! tcp/udp seems to work properly though. I can ping hosts on the Internet from machines on the LAN segment. I'm not sure where to begin troubleshooting this problem. Any ideas?
