Port Forward over ssl site-to-site

Question

I am trying to port forward over an ssl site-to-site tunnel. I have two sites that have an ssl tunnel working, can ping across the tunnel and access items on both sides. What I am trying to do is have an stmp connection come in to the public IP of site A and then hit a mail server on site B. I suspect the issue is with the return response not coming from Site A and just going out Site B. How can I accomplish this goal?

Hi MichaelPousen : Hope site A is acting as in SSL VPN server and site B is acting as in client. Can you please confirm "Public IP of site A" (host IP) added in the local LAN network details over site A end and this latest file imported on site B client end. (so site B know this public IP routed through the tunnel). If this part or setting already done then you may check tcpdump on site A and site B to confirm more on request and response.

Basically i would recommend to move to a modern solution like RED or IPsec Site to Site. Then use a simple NAT.
