This may be confusing to some, but you shouldn't be surprised by this. The three servers are only different by name and 'business model', but the urls all go to the same virtual spot. This modified IPTV Stalker has the three different servers names and urls, however when it is called by an outside program, the code will use what ever credentials are in Portal 1. So, yes you do have to completely configure Portal 1 with the same MAC and serial number etc. You do not change the "Server Name" or the URL.
