IP address questions

TehTech · 12-02-2008, 12:13

Hi! I am having problems with my modem & the ports, whereas I cannot participate in online gaming or use any torrent client as the modem has NAT mode enabled, and no matter what port I try to use, i get the same problem.

Just spoken to TS, and they said I need to fork out on Ãƒâ€šÃ‚Â£10 for a fixed IP address, and this will surely solve the problem.......

The thing is, in the modem config pages, there is nothing at all in the way of Port Forwarding options, the status says NAT mode enabled, but no option to turn it off, can ANYONE help me plase?

AFAIK, Virgin don't offer fixed IPs on their residential services. Also, a fixed IP will make no difference at all if you aren't running a server. If you are, it just makes your server easier to find.

Also. AFAIK, Virgin's modems don't do NAT.

Sorry Stuart, I forgot to mention its the 10Mb business broadband package!

Damn modem, why couldnt they enhance the built-in webserver to include port forwarding & NAT options as routers do

Fair enough. The comment about the fixed IP being unlikely to make a difference still applies though.

Which modem is it?

Its the NTL: branded 2050, its just like the new VM 255's but with an added USB port.

Tech Support seemed to think that a static IP address would be the ticket, as a while ago he helped out a cyber cafe by charging them the 1-off Ãƒâ€šÃ‚Â£10 payment for a fixed IP address, and aparently it worked, but Im not convinced myself...

Unless NTL route their fixed IPs differently (and I am pretty sure they don't), a fixed IP will make no difference.

Also, the resdential NTL 250 (which is the 255 with USB port) doesn't do NAT, or have a firewall. Not too sure if the business one does.

Hold on a few mins & i will get some screenies of the config pages!

If anywhere it'd be in the firewall section.

Unfortunately not, the only options are here:

EDIT:

I have tinkered around with all options in the settings, but it dont help, would I need to speak to TS again to see if the next agent has a clue?

Are you using USB or Ethernet connection ?
Presumably you're using the 192.168.0.x/24 internally ?

Does "Protection against incoming connection requests on routed subnet" option make any difference ? (I'm guessing not - but worth asking.)

I am using the Ethernet connection mate & yes your right, it does use the 192.168.0.x ip address.

Nope, no difference at all, when I first discovered this issue, I did try unticking everything, after all, I have a firewall on my laptop that has never let me down, but i really do not know, dont the business side have a 6hr SLA or something? after all, thats part of the reason this package is so expensive!

I'd resort to calling them !!!

This page is very old ... but does show NTL Business modem (I appreciate not the same model as yours.) having a forwarding option ...
http://www.chetnet.co.uk/articles/in...v2&id=108&c=19

I'm run out of usefulness I'm afraid.

Good luck

No worries and thanks for taking the time to try and help!

Looks like I shall have to call them up again (hopefully I will find someone that knows what they are doing & talking about there!)

Thanks again
