Just FYI, in case anyone cares, I was able to access my linux box at home this morning after putting my modem in "Bridged" mode and setting the router to do the authentication. Had to power-cycle both the modem and the router to get it to "take" but it's working now. :-)
So, if anyone has a SpeedStream DSL modem and suddenly finds that their internet has stopped working and your ISP says "everything is fine here," you should check to see if your modem has been taken out of Bridged mode. :-) ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
