I have a PIX 501 and Comcast Cable and have been running fine for several years. Recently the Comcast Wall Garden software has been popping up (It states if your a new or existing customer contact Comcast or download there software) and Comcast tells me to reboot the Modem and the Firewall. This fixes the issue for a brief period and then that WG software returns. I also have a PowerBook and IBM Thinkpad attached through an AP 1100 and they also will get the WG. I have direct attached my laptop and desktop to the modem and there appears to be no WG issues. I upgraded the PIX to 6.3 and PDM 3.0(4) and the issue still persists. I am completely flabberghasted and out of options. Anyone have an issue like this?
