Hello,

I am making CIPE VPN tunel and I want add one Win 2000 computer with public 
IP address into our company's LAN. We have RH linux 7.1 as router where we 
are runing CIPE 1.4.5. On another machine is Windows 2000 SP 4 installed and 
there is CIPE-Win32 version 2.0-pre15. My tunnel works fine, I think - I can 
ping left and right end of tunnel from Linux (ping 192.168.3.1)and Windows 
(ping 192.168.1.2)too. But I can´t ping on another machine inside my network 
(ie. 192.168.1.15) or inner interface in my linux router (ping 192.168.1.1). 
I tested packets with tcpdump and ping and packets from RH linux router goes 
into tunel fine, but ICMP requests from Win 2000 aren't coming back.

Can anybody help me?

Thank you very much.

ME=rh-linux.public.ip:5000
PTPADDR=192.168.3.1
IPADDR=192.168.1.2
PING=5
route add -net 192.168.3.0 netmask 255.255.255.0 dev cipcb0

routeru's interfaces:
