I noticed a problem with the Cisco VPN client and CoLinux ethertap.
My Colinux has two virtual devices:
1) A slirpd (this is used for Internet/Default GW)
2) A tun/tap devices (used for speeding up X11)
After I installed the Cisco VPN Client for Windows XP (32bit) I have some troubles. This goes away after deinstalling the VPN Client.
My ethertap device has the IP 192.168.55.40 inside CoLinux and 192.168.55.1 on the windows side. The strange thing is i can ping the 192.168.55.40 IP from windows, but the Colinux side can't ping anymore the 192.168.55.1 Windows IP. That is strange. I can also ssh in Colinux using the 192.168.55.40 IP.
Any ideas? Is this a ethertap problem?
Bye and happy hacking.
