Running SELECTserver on a different Port in IIS

(Posted on behalf of a user;)

We want to switch to a new SELECTserver. The following two questions have
arisen.

 1.) On the new Server we configured
the SELECTServer Web services on IP port 81. To open the SELECTserver managed
sites web site we have to enter the URL specifying the IP port (http://server1:81/BSS/Admin/).
Is this IP port specification now also required for activation?

 2.) On which IP port send the ELS
client his usage to the Select Server now? Is this also the port 81 as in the
activation process?

Thanks in Advance!
