I misread the CONFIG_IP_ADVANCED_ROUTER Configure.help section and
thought that IP forwarding had been moved to a sub-configuration menu.

There was such an item in 2.0.38 but after carefully rereading
the 2.2.14 .help file I'm still not sure what's needed.
You can do "less Documentation/Configure.help" from the linux
source directory and search for CONFIG_IP_ADVANCED_ROUTER to judge
for yourself.

This sounds like IP forwarding is working.

Does pppd have the option "proxyarp" and is it turned on for the
ethernet in /proc/sys/net/ipv4/conf/* ?  I don't know how that pppd
option plays with IP chains, but it's commonly used to tell the other
machines on a LAN to send packets bound for the call-in (the Win95)
to the Linux box with the PPP connection.
