VPN w/ NAT on external IP in same range as VPN IP

L3 Networker

maybe that title was convoluted but i need some feedback for somethiung i have not done before.

setting up a VPN but the other party says they DO NOT allow internal addreses over the VPN to their network; so i cant give them proxy IDs of 192.168.0.0 10.0.0.0 etc... it has to be an internet routable IP.

So,,

I dont have any proxy IDs

Im using an external internet routable IP from the same range im using to setup the VPN.

eg:

IP for VPN: 5.5.5.5

IP for "interesting traqffic (IP i will send packets with): 5.5.5.4

I will NAT the traffic out 5.5.5.4 while the 5.5.5.5 is used for the VPN tunnel.

I tried to use the same IP for both the VPN and the interesting traffic IP but the PA would not let me commit that, thats fine.

Is this going to work?

I ony have one chance to get this right before there is a change freeze over the holidays.

thanks

choff123,

I just performed a quick lab of your requirement and this requirement would work just fine.

There are no special caveats that I needed to put in place to get this working. I only needed to configure a bi-direction NAT for my real private interesting traffic and the NAT'd IP that would go over the tunnel; 5.5.5.4 in your case.

Let me know if you run into any problems performing this in your environment.
