Well i have to hand it to them, the sp2 firewall is mighty powerful. As you know, vanburen, I (used to before my last comp died yesterday ) ran that DC++ hub for me and the other 250 users , and when i upgraded to sp2 ( huge mistake) i couldnt for the LIFE of me figure out why noone could get to my hub! If i went thru my router ip i got in fine. But if i tried thru the no-ip addy, or thru my ip address, it was damn near impossible. I finaly found out it was the sp2 firewall but MAN! What a pain in the ass that was.
