I appreciate all the information and the attempts to help, but so far nothing has resolved the issue. My friend and I are still receiving the same messages about joining games. We both have configured our routers and firewalls to allow the ports. Also, we both have completely turned off our firewalls with our same configurations and still experience the same issue. However, I was able to join a random players game, so I don't believe it is a B.Net issue. Any other sort of ideas as to why we're unable to join the same game?
I suggest bypassing the router by plugging the modem in directly to your computer. That will tell us if the source of the problem is your router or not.
Usually I don't like to have the user disable the firewalls, it could cause there problems, and decreases security. Also, sometimes while disabled, firewalls will still block the traffic. This is why I recommend enabling and configuring any and all firewalls installed.
If you owned the game, you are allowed to have at most 1 copy (by the EULA). Many Gaming Centers just use Alcohol120% or whatever it's called, which is just an ISO-image client. You're having port issues. You'll need to configure your router and/or any firewalls you may have. You can learn how to do so here:

Please note that disabling your firewall will not cut it.

Of course Diablo1 still has Battle.net, ;P.
