PPP - I can ping but that is all 1

[wires]

This is driving me nuts!

I have a linux machine (based on RH) running pppd 2.3.10. I can connect with a windoze machine, get logged in and ping away. That seems good. However I cannon access any services on the linux box. No HTTP, no ssh, no time, no samba.

tcpdump -i ppp0 shows the incoming requests but that is all.

Any ideas?

Do you have the services running on ppp0?

Looks like a firewall problem to me.
