I have the same issue....sort of.

If I make a connection to my work VPN, I can surf ok.....but if I disconnect my work VPN via VPNC, then I cant even get to WWW.GOOGLE.COM. Powering down and powering the N810 doesnt seem to fix the issue.

But if I type in the IP address, I can go to google.com....or any website. I have tried opendns DNS at 208.67.222.222 and 220.220, but it didnt do anything either.

Any help would be great....
