I am using the latest Ubuntu distribution... and I have a rather spotty VPN connection. I am using the default Network Manager application that came with Ubuntu.
I am having trouble maintaining a connection to my VPN, and that being a separate issue, I'm looking for something to make me a little bit more secure. I would like an automated way to shut down either specific ports when the PPTP VPN drops connection, or to kill an application at that time... Even better yet would be to reconnect to the VPN while halting traffic.
Anyone know of an application that does this for Linux / how I can configure IPTables to block the ports?
