Hi
I am wondering how i can get iptables to do a PAT based on source IP address?
Traffic from 10.5.1.0/24 towards UDP port 69 should be mapped to port
20000 instead of port 69
Traffic from 10.5.2.0/24 towards UDP port 69 should be mapped to port
20001 instead of port 69
Is this possible with iptables?
Thomas

Hi,
With iptables (almost) everything is possible. You should look around
the target SNAT

I am sorry, I gave you the wrong target. DNAT matches better your goal.
