And once more --- would like my NAT set to open for Xbox 360

[#1]

Hallo
have tried all ways to get an open NAT -- I'm obviously techno stupid...
Have a MAC so this doesn't work      -----                  "if you dont know how to open ports look on youtube or go on http://portforward.com/ "  - I'd pay the bloody cash just to get a result
got a Thomson T585v8
upnp - on
ext sec off
ports  88 udp  - 3074 tcp - 3073 udp
has anyone a nice step by step guide lots of pictures way to do this --- if I don't get this sorted soon kids are gonna "get medieval on my ass"  ------ their language not mine 
first day off - hardly stress free,,,,, where's the gin
cheers

We've a guide which fixes this:
http://community.plus.net/library/gaming/increasing-gaming-compatability-with-the-thomson-tg585v8-xb...
If you've run the cmds before, we've tweaked the guide since then.  Read it carefully

Unfortunately I've a MAC so this doesn't apply...
You will need to connect to the router via telnet.
If you have Windows 7 or Windows Vista then you will need to install the telnet application first.

However - found this on net --- and with a little mix of both guides
If you have a MAC + XBOX 360
Goto Applications > Utilities > Terminal
do this
iMac:~ *****$ Telnet 192.168.1.254 23
