Introduction / Summary:
I have IM on remote PC and wants to access UIM probes from outside the firewall but want to open minimum port(s) in firewall.
Currently it requires wide range of ports(48004-48050) to be opened in the firewall.
From outside the firewall, set up secondary hub having tunnel connection to the primary hub and then run IM on the secondary hub machine.
In this case, the connection uses 48003 or 443 port between the hubs so the firewall only needs to open this minimum port(s).
