Hi there! I've been doing some research on using VPN (kernel 2.6.x) with iptables and I'm having trouble with both of them: Having two PCs, one Windows XP and another with linux, IPsec seems to work fine on both and all comunications between them are encrypted. The problem is when I execute this command with iptables in linux box: iptables -t nat -I PREROUTING 1 -d x.x.x.x -j REDIRECT --to-port 80 (and all the policies are to ALLOW) The redirection fails... If I deactivate VPN, the redirection works ok. What problem could be between VPN and iptables redirections? Any suggestions would be very appreciated. Sandra
