Please kindly help me with the scenario below.
We are trying to establish the site to site VPN with a partner who only accepts public IPs as encryption domain. Unfortunately, we have only one public IP address for internet access which means we are doing NAT overload.
My question is how can we configure the same IP assigned to our VPN gateway as encryption domain and map to the original private IPs.
Thank you for the quick response and information. Unfortunately, Our router is not ASA so it is not possible to configure nat (inside, outside). However, we will try to translate your suggestion on the router.
