Hello once again

XP Pro with SP2 desktop pc = host pc
We have Thomson Speedtouch 570 Router/modem, connected to this pc (host), also have another desktop pc and 2 laptops all connecting to this router/modem wirelessly (host is wired connection). All pc's are able to log on to internet and file and printer share............so no problems there.
The problem we cant solve is how to configure the router/modem's embedded firewall , as all the pc's on our network each have their own firewall we want to turn the embedded one off.
I have followed Thomsons instructions on how to do this...........but...........you guessed it.........their instructions aren't working for me

I have opened command prompt and typed in telnet 10.0.0.138 as instructed but i get the following message when i do
Connecting To 10.0.0.138...Could not open connection to the host, on port 23: Co
nnect failed
after this i should be able to type
firewalling off (but have not got this far due to previous message).
I have checked that i am getting the correct ip number.........following is read out from ipconfig/all:-

I have also tried to change the NAPT ports so that messenger and bearshare are able to connect, by typing http//10.0.0.138 into explorer and accessing the thomson interphase page.
I miss being able to download music directly to this pc (can still do that via other pc's on network) and also miss messenger on this pc but again the rest of home network is able to connect to messenger.
If anyone has any ideas as to how i can turn the embedded firewall i'd love to hear from them.
Thanks for reading my problem
