I have a strange porblem that I believe is related to the PIX firewall we are using.
Certain websites are being blocked and they seem random. uplinkearth.com, techguy.org and ohers. I can access these sites by byepassing the PIX and going straight to the modem.
We do have websense running and for testing purposes, we turned off the websense server. This did not help, so we can rule out the websense software. We have no other filtering progrmas installed.
Oddly enough, this all started after a internet service outage in our area. Internet was down for half a day. I talked with comcast in length because it seemed logical that this was a residual problem from the outage. However, since I can access all sites without the PIX, I had to give up that persuit.
I'm not very familair with the cisco pix, so looking at the current config does not lead to any clues for me. I just know that, nothing changed except the internet outage.
I have recycled all equipment, modem, pix, servers. Just to make sure.
