It's possible. Add the cert and tell the users to connect via https vs. http. Enforcing would be something that would be far easier if you had an ISA machine between the dial up users and your server.

Reason for this is, we want our users on the network to still be able to connect on port 80 and users coming in from outside our firewall via dial-up to connect on port 443.
