Useing a 1700/VPN/k9 or a 2600 Router with FW feature set.
I am curios to know if there is a way to configure source based PAT,
such that the PAT changes depending on the source of the traffic.
Perhaps with multiple routemaps?
Example:
[ext source IP] [internal IP] [internal_port] [external IP] [external_port]
172.x.x.144 10.x.x.14 2000 192.168.x.14 2001
172.x.x.145 10.x.x.14 2001 192.168.x.14 2002
172.x.x.146 10.x.x.14 2000 192.168.x.14 2003
172.x.x.147 10.x.x.14 2001 192.168.x.14 2022
I am aware that this is ugly, however this is a legacy from a Linux IPtables firewall.
