It's probably that ip forwarding is not enabled. To check, cat /proc/sys/net/ipv4/ip_forward If it returns 0, then there's the problem. sudo echo 1 > /proc/sys/net/ipv4/ip_forward and add the line net.ipv4.ip_forward=1 to /etc/sysctl.conf to preserve over reboots. hth, Steve -- Steve Holdoway BSc(Hons) MNZCS <[email protected]> http://www.greengecko.co.nz MSN: [email protected] Skype: sholdowa
