hi vram,

ensure that /proc/sys/net/ipv4/ip_forward is set to "1" - use

'$ sudo echo "1" > /proc/sys/net/ipv4/ip_forward'

Then enable masquerading:

'$ sudo /sbin/iptables -t nat -A POSTROUTING -o $eth0 -j MASQUERADE'

where eth0 is your external interface.

That should do the trick.

hth,
christoph
