Not sure which ‘flavor’ of Comcast Internet you have, but I had a client that switched from Comcast Business to Comcast Residential for their home office. The Comcast device would learn the MAC address of the connecting device. Any chance the Comcast device you have is still looking for the MAC of the Netscreen ? Can you clone the MAC of the Netscreen within the SonicWall interface so it looks to Comcast like the Netscreen ?

' From: Evan Brastow [mailto:ebras...@automatedemblem.com] Sent: Friday, August 27, 2010 12:06 PM To: NT System Admin Issues Subject: SonicWALL and Comcast Happy Friday peoples and peopettes, Has anyone had experience setting up a SonicWALL firewall (NSA 2400 to be exact) with Comcast Internet service? My consultant came down on Tuesday and we gave it a try. He set it up, we put it live on the network (replacing the Netscreen that's there,) and things worked for about 10-20 minutes, then we were unable to load any web pages. We could ping sites like www.google.com, but not connect via the web. We called Comcast, and they weren't any help. He called me yesterday and told me to change my DNS forwarders from Comcast to Google's 8.8.8.8 and 8.8.4.4 servers, which I did. I'm going to try taking out the Netscreen and putting the SonicWALL back in over the weekend, but I just wanted to know if there were any well known gotchas?
