change ip address for Virtual server

Hello,

I have couple questions about the SSL in Virtualmin, and I know hot it works regarding the additional ip address etc...

So, in my case I am now running one web site which uses SSL (https://) and a lot of other web sites that only uses the http:// no SSL ...

Now I ordered an additional ip address and I have assigned it to the servers NIC card, configured ip, mask and gw....

My question now is as follows:

I know when we are creating a new virtual server than in the "IP address and forwarding" tab I choose the Virtual with IP and NOT shared IP, than I just type the Virtual ip and everything works just fine...

BUT when I already have an Virtual server up and running which uses shared IP address as default, how can I add this new Virtual ip address in this case ? because when I click on "Edit Virtual Server" and than on the tab "Configurable settings" I see only the option "External IP address" and i can type a new external ip address, but this is not a Virtual ip address, because I tested this I typed a new address here and than I tried to add SSL on to this Virtual server and I received an WARNING that ip address is already used by another Virtual server for its SSL.... so how and where can I ADD a NEW Virtual ip address for Virtual Server ??

Thank You

Amel
