Norton Internet Security blocks VPN access

I have to disable the firewall in Norton Internet Security 2007 in order to access my company VPN. What do I need to configure in Norton to allow VPN access without having to turn off the firewall?

If you double-click the firewall icon in your system tray, you should be able to configure the firewall settings (under "Client Firewall" click Configure)... in there, go to the Networking tab and ADD the name or IP address of your corporate VPN gateway to the Trusted zone...

Should be straight-forward to make the change, let us know how you go... this is based on 2006 but expect it's exactly the same

Thanks Herbus your tip prompted me to take another look at the settings. It's different to how you describe. I went to Personal Firewall > Trust control. I couldn't add my VPN as I don't know the IP address but with the firewall off I went to Active & added the VPN connection as trusted - but with the firewall turned on I still cannot connect. I wonder if it is something to do with the general rules > advanced settings & allowing one of the protocols?

OK, soz I didn't realise they've changed the interface in 2007...

Anyway, hopefully still easy enough to sort...

If you don't know the IP of your VPN, won't it allow you to type in a name? ie: myvpn.company.com
If not, then so long as you know the name that you connect to (you could check this in the properties of your vpn setup), then you could ping it to find out the IP address (even if the ping doesn't reply it should still resolve to an IP address)...

If you get through that then try throwing the IP into the trust control bit...

What I suspect is that when you have the firewall on and when you have it off it might be running in a different 'profile' mode or something, so maybe changes you made when it's off don't apply to when it's on...

FYI, this has been a common problem with norton's firewall for at least the last couple of versions... have never had to mess with protocol configs, just tell the firewall that address is trusted.

Let me know if you're still having trouble after this and I'll see if I can dig up some 2007-specific info or I'll install it myself and see...

Cheers,
Herb

Herb, I tried that but when I ping the host "vpn2.carriustech.com" I get the message "Ping request could not find the host..." even when I am connected to the VPN & firewall is off. IP config gives me a gateway address in the 192 range for the PPP adapter for Carrius but I assume that is not the IP address of the host.

That's weird,.. sounds like you're having trouble resolving the name of the vpn ontop of anything norton is blocking... anyway, now that the cat's out of the bag, I've tested name resolution and it works fine... it points to 199.227.239.197 so try adding that to norton and see if it helps.

If STILL failing, it'd be nice to know whether your ping attempt spits back an IP when the firewall is disabled - would indicate it's blocking DNS lookups for the vpn name, which would be surprising, but let us know...

Adding that IP address solved it & the ping works too now?!?. I can now connect to the VPN with the firewall on. Thanks a lot for your assistance.

Still quite bizarre - blocking the VPN connection is one thing but norton stopping you from finding out it's IP address sounds weird... a new quirk in 2007 maybe?

Anyway, a happy ending, glad to help, happy it's sorted & thanks for the points
