Just tested a newly purchased Dlink DIR-601 router for our son to take back
to school...
Left it setup with the local 192.168..0.1 address
and plugged it into our local 192.168.1.x network to get a WAN side DHCP
address.
Worked fine - hardwire and WiFi -

I also think I stumbled onto what I thought was an ICS or 192.168.0.1 issue
that I posted in another thread,
but now think it really is the uPnP router feature/setup.
I have that feature disabled on my local routers,
so never really saw it pop up on Windows Network Connections (XP).

So - I read about what uPnP does,
and wondering if and when it really should be enabled ?

The short answer is that uPNP allows a application to request a port
forward or other router configuration changes without manual
configuration.

Some routers have bugs that allow malicious software to have more power
than they should, but as a rule this type of exploit needs malicious
software already running on the PC anyway, so it's like being a little
bit pregnant, there's little practical difference between being
compromised and being more compromised.

That "rule" is incomplete -- there are also _external_ exploits.

That being said, I'd turn it off and configure port forwarding manually
in most configurations.

Good advice.
