If that is the problem, then there are good, free, firewalls and Antivirus programs. I use ZoneAlarm (http://www.zonelabs.com) and Avast Antivirus (http://www.avast.com).

No I do not have a router. just one pc connected via cable modem. I only found out i was going through a proxy server when i checked via the connections tab in the navbar on this site. And this returns the result saying that i AM an ntl customer.

Tools,internet options,connections,lan settings..

Interesting Grandmaster, This i have not checked. I only found out i was going through a proxy via the connections tab on this site, (see previous posts)
I will check as soon as possible as im not on my home pc at the moment.
Cheers

did you resolve this?

bollyrotten · 05-01-2006, 12:47

No Mate not yet.

I did look at the internet options , lan settings, but no proxy was listed + it needed a port number which i dont know. I presume port 80?

In my network connections, i do a properties and see my ip address and sub mask, but no proxy there. Thats why i was supprise to know i go though a proxy. But acording to the connection tab in hte navbar on this site i do.
I have no idea why netguard thinks im not a NTL customer. (Ihave not rang customer services yet or had an email back from technical support)
I would be grateful of any advice at the mo.
but i think it will look like going back on sygate firewall & avg antivirus. Just wanted to try the software seeing as it is supposed to be free for ntl users.

cheers

Proxies should be set to port 8080, not 80

Cheers Ian, I was only guessing at port 80 as its internet explorer port.
I will give it a go.

thanks

Should you not be set to DHCP, rather than have an ip address listed?
Dont have a cable modem so not sure....

Except that being behind a router is entirely irrelevant. The router picks up the ip from the cm, then it translates ALL internal addresses on the way out to the real address. Do a quick google search on NAT. The internal addresses (anything 192.168.*.*) are not routable over the internet and therefore CANNOT be seen by NTL.

ahh but the netguard software could in theory looking at the ip of the network interfance on his pc, for all i know it could be looking at the wrong adaptor or something. really depends on what netguard does to determine if you are an ntl customer or not wether it simply looks at your pcs ip address from your network configuration or wether it calls some server on the ntl network and does the ip lookup that way.

And netguard is useful because...?

Err, I am Cisco qualified. I know how TCP/IP works, and how NAT works.

My reasoning was that IF netguard needs some sort of activation code sent by NTL (or the original manufacturer), then it may embed the machine's IP in the request for activation. Thus the code would only work on a machine with the same IP as the machine that requested the code.

A lot of software does this.

So, no, being behind a router is NOT irrelevant.

Yeh, biggie, so am I. Unless you are running an "enterprise" load then the internal NAT'ed ip is NOT passed through to th e far end. Don't believe me? try running CallServer from NAT to NAT without Enterprise at each end. what's that I hear, oh yeah SILENCE. And yes, I have worked with the R&D guys in Tasman to get that sort of service working (4 years ago if memory serves). Jeez. And besides, how many people do you think are running any sort of Cisco (and I don't count Linksys here) boxes at home??

OK, seeing as you have totally misunderstood my point, I will try to explain a little more clearly.

If you are behind a router or firewall with NAT and are running a PC running Windows, type ipconfig, what do you get? The IP address assigned to you by NTL, or the IP assigned to you by the router/firewall? Yep. You get the IP assigned to you by the router/firewall. Windows does not know it's connected to a router. All it knows is that it is connected to a device, and has an IP.

Now, I bought up the Cisco qualification because you appeared to be assuming I do not know how NAT works. I was making the point I do. I also know that the NAT IP is not passed through to the internet connection. I did not do it to start a contest.

Anyway, back to the point of the post. Some software that requires activation uses the IP as part of the ID code for the computer. This, IMO, is a bad idea, but some software does it. When that software requests the IP from Windows, what IP will it get? Yep, the IP assigned by the firewall.

Now, if Netguard does this, it's entirely possible that NTL will not recognise the code as containing an NTL IP. They should recognise it as a member of a private range, but this is NTL we are talking about.

Hopefully, you can now see that the make of router is not relevant to my arguement.

However, the OP has stated he doesn't have a router anyway.

Slightly different query this -but still Netguard. I installed Netguard on a new laptop computer, which is connected to NTL Broadband via a wireless router. The installation was fine, but I noticed it must have deleted some essential files for Windows updates, as I was not able to upload any of the windows updates with Netguard installed. The message was that registery or essential files were missing. Even though I tried to restore these files with the method offered, it still would not permit the updates until NetGuard had been uninstalled.
Has anyone else had this problem?

bollyrotten · 12-01-2006, 09:10

Hi Guys,

Many thanks for all your advice. I did manage to get netguard un and running in the end but using magic! lol It somehow fixed itself!!

Every time i switched on the pc i got the message "youare not an NTL customer etc"
Then the other day, bingo! it just worked!

However im not that impressed with it in the end. It cannot scan my pc for virus's does my C drive fine, but my D drive will it dont like that! I left it running for 8 hours doing a scan, and after that time it was still on 50%! it was still running acording to the task manager (process 100%) my d drive contains about 80GIG of files. AVG would scan in about 1 hour, I know my machine is clean because its recently been formatted and whilst netguard wouldent run i had to re install avg which scans were clean!
Looks like i will have to un install and go back on avg & spysweeper or something.
cheers guys
