We have recently acquired 3 companies and all are using 192.168.1.0/24 as their local subnet. Now in a perfect world I could just go on-site and and change the addresses, but as well all know it's not and they have critical services running on AS400 systems that need to remain online during the transition. So here is where NAT comes in. I need to establish 3 IPSec tunnels and basically say that when traffic is going to 172.16.200.x (for example) go through tunnel.200 and change the IP back to 192.168.1.x. And...when traffic comes from 192.168.1.x through tunnel.200 change to 172.16.200.x. I know this can be done (as I have done it on Cisco and SonicWALL), but am just drawing a blank on how to set it up on the PA. Any thoughts?
