After Cisco AnyConnect VPN Client connected access to Internet sites becomes unavailable.
I have Asus laptop with Windows 7 64-bit Home Premium which I want to use for work from home. My company provided me with special website from which I'm able to successfully establish Cisco AnyConnect VPN connection. But each time after this VPN connection has been set, I loose Internet connection, so I cannot open any website on my Firefox, Internet Explorer, my Thunderbird e-mail box also becomes unavailable. And the only way to get normal Internet connection back is to reboot my laptop. I asked for the help support guy who is responsible for VPN connection in my company. He checked my proxy configurations both manual and automatic, and some other things from VPN side, but found nothing wrong. So he thinks there is something inside Windows 7 which blocks network access, but he is not Windows 7 expert. Also, when I bring this laptop into my office I'm not able to get access to any external or internal websites, or e-mail. All I can do is to ping to any available machine, but only if I use machine's IP address. ping to machine name does not work either. But at home getting Internet access to public website or e-mail is not a problem. Please advise.

You've probably got two different issues here. The first one, losing local access when you establish the VPN tunnel is because the VPN connection on your computer is set to use the gateway on the remote network. I don't know what client software you're using, so ask your IT guy how to change it. The second one, not being able to resolve names when connected to your office network, sounds like you're using pre-defined DNS servers instead of letting DHCP assign them. If you don't know how to check this yourself in your network settings you can have your IT guy check this too (it's pretty much the same as it was in XP.)

Thanks Bob, I'll check the second problem with my IT guy tomorrow, but concerning VPN problem, as I mentioned in the original title I use VPN client named "Cisco AnyConnect VPN Client". Contrary to older Cisco VPN clients, AnyConnect graphical interface does not contain any meaningful buttons like "Properties", etc. It just has a couple of informative buttons "Statistics" and "About". So there is nothing obvious for me to change on client side. Sergey

With the AnyConnect client have IT look into "split-tunneling" settings on the back-end.....that is, if fixing the DNS issue doesn't resolve the VPN issue as well.
