port 443 - Base License

Hi

I have the following problem
I have a NAT Rule to my Exchange on port 443 and 80

The NAT Rule to Port 80 is working without any problem but 443 is not respondig.

I think the problem is that the user portal is on port 443 but I can not change it because this option is greyed out because of the license.

Its just the base license!


Any idea to fix this?
