ygsmilo,
you should have a IP address ( read URL ) you can type in that will bring up your router in Internet Explorer and you can set up your connection via this access.
my D-Link router is set to never close any sessions I got programmed, if you find that AH shuts down in say a week or a month, you may need to go set this particular connection( session) to stay open permanently.
Skuzzy &/or Lew ( Silat ) is pretty knowledgeable about this stuff may want to check with them in regards to your vulnerability.
sounds like you got it all fixed up though
if you use WinXP, "MY OPINION" is turn it off permanent and run a backup software type firewall like zonealarm. I noticed a big difference in using zonealarm over the built in WinXP firewall ( closed alot of hidden holes )
but to each his own ya know,
good luck!
