I got combo modem/router from AT&T to replace old equipment damage by power outage. For 6 years I have been running personal Web Server (Apache Tomcat) on my computer with DynDNS support. With new router my server is still seen by internal IP (192.168.1.112) but not accessible from the outside.

I have spent about 12 hours on AT&T chat + AT&T Customer Service phone but it did not help. When it came to the words "running web server" all the representatives read me literary same mantra that they do not support problems with my server. Obviously they were all instructed to tell that to sell this 7550 buggy device.

Am going to return it to AT&T store. Would have switched to a different provider if could
