Port 80 sharing?? or reconfiguring

[Tony]

I have a little problem to solve

I'm using MS IIS on a windows XP PC to serve a little program which
monitors water quality in my home aquarium, its set to use port 80 on
LAN address of 192.168.2.44/aquanotes, The internet access is by a IP
substitution service ( no-ip ), I'm using a router and its been setup
to forward port 80 ext to port 80 internal.
This works well, the problem is that I have a netcam which has its own
built in server, by default also using port 80, so I've had to change
this to another port, ie port 1024..( router setup to allow port 1024
LAN for netcam is 192.168.2.55:1024 )

Again locally and at my friends house this works well but at work its
a different matter , I cannot access the netcam presumably the IT
department is blocking ports other than port 80.

Is there a way to configure my setup so as to allow both to use use
port 80..

Any help will be welcome

I am not familiar with IIS, but Apache (which is typically Unix, but
available for Windows) can proxy other web servers on same port on your
LAN. It is configured like NameVirtualHosts, but instead of system path,
can access another server. See Apache docs for mod_proxy and ProxyPass.

To access the other server (webcam) you would need another name, but you
could either configure your no-ip.com to have *.yourname.no-ip.com
wildcard and use a name like webcam.yourname.no-ip.com, or get another
no-ip.com name and put the names in a group, so they will both update to
your current IP at same time. I am using 3 no-ip.com names to play around
with virtual web serving and smtp.
