Ever since I changed from a PCI ADSL modem to an ADSL router (or maybe it's just a coincidence), whenever I try to do a Norton update, I get an error message from Norton saying "cannot connect to your ISP". Daft, I know, since I am already connected. I have tried disconnecting the router, and re-plugging in the modem, and trying again, and I have also tried switching off Zone Alarm (even though Norton worked perfectly for a year with it switched on), but I still get the same error message from Norton. Any ideas ? Could it be anything to do with having two firewalls ? Or the switch from the modem to the router ? It's a bit worrying not being able to keep up to date.

I don't know why this would happen or if it's anything to do with having 2 firewalls, but why have you got 2 firewalls? It's not generally considered to be a good thing to have 2, as it can cause conflicts.

Thanks for the reply. I have 2 firewalls because my friend who built and supplied my PC initially put ZoneAlarm on it. He then upgraded me from a modem to an ADSL router, because I was sick of not being able to dial up every time (Broadband just is not "always on", is it , despite what everybody says !!!), and the router - so he told me - effectively also comprised a firewall. True ??? If true, I just haven't got around to removing ZoneAlarm. If I safely can, then my next question is : do I need to uninstall it, or can I simply turn it off ?

I'm sorry, I don't know if that's true or not. I don't even have BB, I'm stuck with dial-up at present. It might be an idea to post that particular question on a separate thread either here or on the Security forum, which might be better. You could put the subject as "Is a router also a firewall?" or something like that.

I don't understand why you have a router?
Have you set up a network at home?
Broadband is "always on", however, for ADSL (i.e. Freeserve)when you switch on your PC you need to connect to the web by clicking on the "dial up" (this is just to let your ISP know you are on your PC - I think) button on your desktop. You can bypass this by dragging a copy of the icon that you use to connect, into the directory C:\Documents and Settings\All Users\Start Menu\Programs\Startup and then every time you switch on, your PC will automatically connect to your Broadband provider.
You're no good for me I don't need nobody, don't need no one that's no good for me!

I would guess your router has what's known as a hardware firewall. That means that it issues a different IP address to your PC after it makes the connection to your ISP. Thus to the outside world your PC becomes invisible and all the traffic is handled by the router. You may need to give access to Norton via your Router setup page.
