• 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. See
for a list of common services and their associated protocols and port numbers.
• 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.)
• Make sure your ISP allows you to run a server and is not blocking the port number of the
NSA’s web publishing feature.
