Hi all. I have been tasked to setup a site to site VPN using IPSEC Tunnel. I have all of the peramiters such as remote gateway authentication and such. My issue is that i am supposed to mask my local host ip to a specific ip that the remote gateway will only accept traffic from. This is the peramiter that I do not know how to configure. Any help would be greatly appreciated.
I little more insight. This is for Surescripts electronic perscriptions filling. I have no control over the remote site. They just give me peramiters and say good luck. Before trying to set this up, i was assured by them that ISA would work. Hmmm...
I have all the peramiters correct except the ip address map. The ip address they have given me to mask is not even close to my external or internal ip and i believe it is a routable ip. It goes something like this:
Router on their side (unknown) --> Tunnel <-- ISA External <-- ISA internal (needs to be masked) <-- Internal network.
"Once Phase 1 is connected, then you must ensure you have created a NAT Policy. The IIS Server IP of 192.168.xxx.xxx must be NAT'd (masked) to appear as 172.38.xxx.xxx. We are only accepting traffic from this internal address from your external address of 96.xxx.xxx.194."
