Netgear DG834G port forwarding & testing

Netgear DG834G

There's a port I need to forward for a game (PES4), and while I can
forward it fine it seems I can only forward it to one LAN IP (from a
single firewall rule). Is there a way of specifying a wildcard so it
gets forwarded to any IP on the LAN? The desktop PC was getting a
different IP (I have a range from 192.168.0.2 to .5 available) each
time, and while I got round this be reserving an IP for the desktop, I
was just wondering if what I ask is possible.

Also, is there a good way of testing a port once open?

Not strictly relevant in this case.

No. You may be able configure forwarding to *all* IP addresses on the LAN
(ie broadcast), but only for UDP. This may only work in one direction,
and/or cause unwanted effects.

The easiest way is to try whatever it is that you required the port to be
forwarded in the first place. The only other general solutions are to use a
packet sniffer or a generic network tool like netcat. For forwarded TCP
ports, telnet can often be used. In all cases, you need to test with a
machine on the WAN side of the router.
