Hi Tony,
I flashed the Router up to the latest 1.4.5 firmware as soon as I got it, and
enabled UPnP too, no I'm not running any Personal Firewall software on the PC -
including the built-in windows Internet Connection Firewall.
If I swap back to the Linksys set-up everything works fine again.
I promise I've looked very carefully at the user guide, honest.
Yes I can see the options to configure Firewall rules for Outbound & Inbound.
For inbound rules (what we are interested in here) you can only set a single IP
address on the LAN interface for where you want to forward a specific range
ports on the WAN interface ( a Service). You can set a range of addresses on the
WAN side - this is so you can specify which remote sites you will allow to make
an inbound connection. This is not relevant here as any remote address could be
the originator.
Normally this option as it states is to allow you to designate a PC on the LAN
to be your WEB server and receive the inbound port 80 traffic, etc.
The example they use for Video Conference has a single PC (192.168.0.11)
configured to receive the CUSeeMe traffic, from a limited range of remote user
IP addresses 134.177.88.1 to 134.177.88.254. Even if this worked it would not be
what I want as I don't want only a single PC to be able to use Messenger Voice &
Video.
Unfortunately the guide has very little info on the workings of UPnP, but I can
assure you the whole point is for it to open these ports through the firewall
dynamically on your behalf, no manual configuration of the Firewall should be
necessary. If it doesn't do this then its UPnP implementation is broken. I have
read elsewhere that it suffered this one way operation, but I naively thought
this was fixed in this latest version of software.
