Is it possible to have 2 servers using port 443 and if so how is the TZ190 configured?

I have 2 broadband lines with both with different static ip's, these are connected to the WAN and OPT ports on the TZ190 using 2 Linksys modem/routers, these linksys routers are configured with no firewall and are just straight through.

I have a https web address that points to one of the static ip addresses and using the wizard in the TZ190 I have opened port 443 to point to an SSL-VPN device

I have another web address that I have pointed to the second IP address and need to open port 443 on the OPT port to point to a server.

I am unsure if I can open a second port on the TZ190 to do what I have described above, or if what i am trying to do is the correct way to do it.

In simpler terms, I have an SSL-VPN device that requires an SSL connection and an Exchange 2007 server that requires an SSL connection, I have 2 ADSL lines both with Static IP addresses, all this goes through a Sonicwall TZ190, i need to know if it is possible to configure the TZ190 to be able to accept two different ssl connections one on the WAN and one on the OPT ports that point to 2 different servers, and if not how else could I acheive this

Any help is greatly appreciated, thanks
