I have four host computers running lighttpd webservers. they are sitting behind a hspa modem, which each occupying a http port between [81 - 84]. 80 is taken by the modem itself.

The port forwarding is setup correctly, however, only a portion of any webpage I request from any of the hosts comes through (they all fails after %20 of the page).

If I put the host on port 81 into the dmz, it serves pages fine. The others do not respond to the dmz treatment.

Is it possible the web content on the hosts somehow require ports aside from their respective http port? Or is it possible that even though the server.port in the lighttpd_ssl.conf file is set, the individual hosts are still expecting to serve on port 80?

I am not familiar with lighttpd, nor did i set them up. they are running on video encoders i purchased. I can grab any files from them required for further information on the problem.
