Hi
 
I have MASQUERADE in a box as a gateway using IPTABLES and I am using that box also for VPN... so for it to work I cant masquerade thaffic that goes to the other side of the VPN...
 
This works for me:
 
IPTABLES -t nat -A POSTROUTING -o $EXTIF -d \! 192.168.20.0/26 -j MASQUERADE
 
but now I have another network at the other side of the VPN (192.168.40.0/26), so how can I invert two networks in the -d???
 
Thanks,
