I am trying to access a Foscam IP camera on a 2Wire network. I have forwarded the port in the network but no matter what port I select it comes up as blocked. I've been using this port check tool: http://www.dyndns.com/support/tools/openport.html. I shut down my Norton firewall which leaves only my ISP (AT&T) as the culprit. I spent an hour on the phone with an AT&T rep and it was a waste of time. She had no idea what I was talking about and was obviously putting me on hold to ask someone else. Any ideas? How do I get AT&T to unblock a port?
