PAT traffic across a VPN so it appears to come from one source IP address?
Posted on 2011-04-20
Our company has a client company that wants us to set up a VPN directly between our offices so we can enter orders directly into their system.
I need to set up a Lan2Lan IPSec Tunnel/VPN and then "PAT" the traffic towards their office ("PAT" is their term) so it appears to them to come from only one IP internal ip address.
I haven't got a clue on how to do this.
I have a choice of 2 routers to do this through -
We currently use an IPCop vsn 1.14 linux-based router.
I have on hand a Cisco RVS4000 router that can do VPN
our internal segment is 192.168.6.x (and of course, they say there is already
a VPN that uses that subnet, so I have to figure out how to work around that also...
As you can guess, I don't really know enough yet to ask this intelligently..
Thanks for the help and the education!
