Do ntl block ports? Having bittorrent and emul problems
 

I was trying to help a friend out with his p2p problem on ntlworld broadband - I did all the usual, opened windows firewall ports, set up the port forwarding in the router, rebooted both for good measure, sat back and did the port tests. And they failed!
6881, 6882, 6699, 55555 ... you name it, I tried it and each time configured the cable modem router (connection via ethernet) and the windows firewall. I've done this same thing so many times for other people, and it's never failed. What am I missing with the NTL config here?

I don't have NTL myself, so don't go asking me anything to specific about the router, but it's a four port job with lots of lights...

And I also tried the "application ports" setting too - same thing. No other firewall is installed

I have a Belkin DSL/Cable Router and if my memory is correct you can put a PC outside the Routers firewall (but then this PC would be open to attacks) I assume other Routers can do this as well (ip 192.168.2.1 is for my belkin)

ntl block some ports but certainly not those. Try running the p2p program without the firewall running, then try it with a direct cable modem connection, see if it goes anywhere.

These are the ports that ntl block.

Hope that helps

I've successfully run Bittorrent on NTL cable, whatever your problem is, it's not port-blocking. :)

:welcome: to Cable Forum by the way, shame on you lot for not saying so sooner. :D

Oops, sorry :)

Indeed, welcome to the site :)

Thank you! I feel all welcomed!
Yes, it's a Belkin Cable Router, and got us totally stumped. Out of interest, is it the port forwarding or the application port forwarding page to be looked at? We tried both.

i had the same problem when i first installed my belkin wirelles router..
after some searching on google i found that by opening port 6881 on the router i was able to use the bit torrent application Azureus.
can open the port by typing 192.168.2.1 into the address bar in internet explorer.. then going for the Initial Setup option (or similar, depending on the router model) then Special Application Port and entering 6881 into the Trigger and Public port boxes.
you can also put the pc outside the routers firewall from here... on the DMZ page... but as stated by david above...this will leave the pc open to attacks..but may be worth trying temporarily to see if resolves your problem
