Need help with UPnP

[Jim]

I'm running an IIS Web Server on one of my LAN XP computers. Everything
works as long as I forward port 80.

I assumed that if I use UPnP on this computer I would not have to set the
port forwarding to 80 on my BEFSR41 Linksys router. Not true in my case -
can't access the server unless I forward port 80.

The reason I wanted to use UPnP instead for port forwarding is because the
internal IP addresses of my systems frequently change (192.168.1.100 may
change to 192.168.1.101 etc).

Not an export in this area by any means but would appreciate help &
suggestions.

Hi
When running a server the custom is to assign a static IP to the computer
running the server.
Then you can forward the port to the static IP and nothing would change any
more.
The BEFSR41 is a very old model, I do not remember if the UPnP works well on
it.
In addition UPnP is somewhat a security hazard, so taking the Static IP
approach is Safer, and works Better.
