I have a ASA 5510 firewall on the outside of my network. I can view a web camera internally after logging into the camera with no problems. On the firewall I created a NAT entry to connect a extenal IP to view the web camera from a public IP. For testing purposes I allowed all IP to connect to the internal address. I can get to the login screen of the web camera, but it does not log in. Instead I get an DVROCXex error. I do not get this same error when accessing from the internal network.
Wireshark shows tcp ports in the 2000 to 3000 in addition to the 80 for the http.
Any thoughts as to what is stopping the connection to the web camera?
