Hi,
I have a installed pptpd, mppe to my RedHat 9.0.

real ip`s

212.2.212.1 --------------- 195.111.111.1

vpn ip`s

192.168.77.11 ------------ 192.168.77.1

I open protocol gre, and tcp port 1721 at my firewall to establish a connection between client and linux firewall. Client is a windows xp.

After dialing my isp my winxp connects to internet and gets 212.2.212.1. I establish the vpn connection to linux firewall. Everything is ok until this point.

My problem is I can not ping the server from client or vice versa.

What shall i do?

thanks,
Ozgur AKAN
