After disconnecting from VPN, DNS queries fail

Reported by: rosarinjroy Owned by:
Priority: minor Component: network/NAT
Version: VirtualBox 3.0.2 Keywords: VPN
Cc: Guest type: Linux
Host type: Windows


My host OS is Windows XP and the guest OS is Ubuntu 9.04. When I connect to a VPN gateway from my host OS, the guest OS's /etc/resolve.conf is updated with the DNS server info for the VPN connection. When I disconnect my VPN connection, I no longer able to connect to any of the web sites from my guest OS. When I do an nslookup, it is unable to resolve the names. The /etc/resolve.conf is still having the old name server entries for my VPN connection. Even after running dhclient multiple times, /etc/resolv.conf is not refreshed with the right server entries. But from my host OS, I am still able to resolve names and connect to Internet.
