j500ss, the ports are randomly picked by Aces High to establish a stable connection with the server, in this case HTC. Whether or not that connection will remain stable is questionable since at peak hours some packets will inevitably get lost somewhere along the route to HTC's servers.
However, opening the ports means you will probably have less interruptions from untimely disconnections since AH has a wide variety of ports to choose from to establish a stable connection without being halted by your router's firewall. Anyways, I'll get straight to the point. If you don't know your router's password you will have to contact the company that made it. Get in touch with their technical support guys. You want to find out, "how to reset the user-name and password to gain access to the router's configuration panel." The tech support people will be able to help you reset the user-name and password so you can get access to the configuration panel.
There is another choice, though. If you don't want to call tech-support, simply look for your router's model name / number and google it. For example, the Linksys WRT150N. Enter it into google similar to this: Linksys WRT150N default password
Once the search finishes the first thing I see is this:
SG :: Linksys WRT150N Wireless Router
SpeedGuide.net Broadband Hardware Database - Linksys WRT150N Wireless Router. ... Default admin username: <blank>. Default admin password: admin ...
So I click it, press Ctrl + F. Now I search for: admin
And voila! There is the information on the default user name and password of the Linksys WRT150N. So, if you setup your router as most do, your router is probably still in default mode using the factory default user-name and password. So try searching for it and perhaps you get past the authentication screen. If using the default user-name and password doesn't work you will have no other choice but to contact tech support to have your router's user name and password reset.
Have fun!
