Hi Folks, I have a network that is setup in the following way: www.dropbox.com/s/dt7q9owe5y997ug/Drawing1%20%282%29.jpg As you can see in the drawing I am trying to access a SMB share over a port forward (DNAT). The issue is that the source address does not get changed on the packet and when 192.168.150.100 goes to reply to 192.168.0.101 it drops the packet as it does not know where to send it. I need to add a SNAT rule to iptables in the Air Router. I am not good with iptables but think it would be something like: iptables -t NAT -A POSTROUTING -o Br0 -J SNAT --to-source 192.168.150.243 This should change the source of the packet to 192.168.150.243. Any advances on that? At the moment it does not seem to be changing the src. I KNOW there are better ways to do it with new hardware etc, but there constraints on solving this problem such that I need to NAT/SNAT.
