Don't bother putting your webserver on a non-standard port.  You can create
a tunnel with SSH from any port on the remote machine to any port on any
host on your network.  My MythTV box doesn't have a direct connection to the
Internet; it sits behind another Linux box that serves as a router (among
other things).  When I'm out and about, I can access MythWeb with something
like this:

ssh -CL 80: alfter.us

-C enables compression, while -L 80: redirects local port
80 to port 80 on (the MythTV box) on the remote network. 
After that, just aim Mozilla at http://localhost/mythweb/ and you're in.

(Note: OpenSSH on Linux will only redirect privileged ports (such as port
80) for root.  My desktop systems mostly run Windows; OpenSSH on Cygwin
doesn't have this restriction.)
