Chapter 20 Troubleshooting

20.14 Web Publishing

A web-published share cannot be accessed by web browser from the Internet.

•Make sure the person trying to access the share is using the correct web address (and port number if the NSA’s web publishing feature is not using port 80). See page 220 for details.

•Make sure the publishing feature is turned on and the share is in the list of published shares.

•Make sure the person trying to access the share is using Internet Explorer 6.0 (and later) or Firefox 1.07 (and later).

•You need to use a public address to access the NSA’s web-published shares from the Internet. If your NSA uses a private IP address, use the public IP address of your Internet gateway (firewall) and configure NAT or port forwarding on your Internet gateway and possibly firewall rules in order to let people access the NSA’s web-published shares from the Internet.

•Make sure the firewall’s public IP address is static or that the firewall uses a Dynamic Domain Name (DDNS).

•Web publishing uses TCP protocol and the port number you specify. Make sure there is not another service using TCP protocol with the same port number.

•If Firefox access to the share does not work, check that you did not set the Web publishing feature to use one of the following ports. (Firefox blocks these ports by default.)
