Satellite web server questions

We currently have satellite deployed and was working. Due to changes in security policy the server had to be moved from where it sat on the network. I am basically just trying to see if I can get my sat server to work on 2 separate networks via one URL(if this can be done).

Previously we had one interface and it served both networks. We will call network1=10.0.0.0/24 for inside and network2=192.168.0.0/24 for outside traffic. We also previously had and SSL certificate for the sat servers url for sat.abc.com, then also subject alternative names for the cert to include the ip address of the sat server.

Due to the move I have added a new 2nd interface to serve the 2nd network. I also added the static route for that traffic. So from one of my outside servers I can ping the new sat servers 2nd interface that was dedicated for outside traffic.

DNS is used to ensure the name used in /etc/sysconfig/rhn/up2date to point to the sat server. Here is the line:
serverURL=https://sat.abc.com/XMLRPC

Since the sat server has now been split how can I get both sets of hosts to start pulling updates again? Can I just add another DNS entry for the 2nd interface to point to say sat2? Then reference that as the new server name in dns? So I will update the config to say "serverURL=https://sat2.abc.com/XMLRPC". Can I just add additional subject alternative names to the SSL cert for the new interface ip address and name that it will correspond to in dns like sat2.abc.com?

Will I need to update the webserver if its listening for all inbound traffic over port 443?

$ netstat -aunt | grep 443
tcp 0 0 0.0.0.0:443 0.0.0.0:* LISTEN

Sorry its so long. I tried to be thorough.
