I have been an Ubuntu user for 5 years and have learned by fiddling, googling, and forum ghosting, so I have moderate abilities. I am running Ubuntu 10.04 from a CD install.
I have been trying to get a vpn working using OpenVPN and privatetunnel.com. I have managed to get it up and running, after some work but there is still a flood of log traffic that's being recorded for all my connections through VPN.
I could not get the vpn working, and eventually tracked it down to firewall settings. The last few steps I did to get past the firewall was use these commands. (I couldn't figure out how to do this on firestarter so I ended up using the cli)
However, even though my vpn will now successfully work, I am still getting a ton of data in my log files. Here's an except with ip's removed.
sudo iptables -F
sudo iptables -A INPUT -i tun+ -j ACCEPT
sudo iptables -A OUTPUT -o tun+ -j ACCEPT
sudo iptables -A FORWARD -i tun+ -o eth0 -j ACCEPT
sudo iptables -A FOWARD -i eth0 -o tun+ -j ACCEPT
Based on this, I think the TUN connection is not being recognised.

Mar 29 13:39:24 derrick-laptop kernel: [122937.318113] Unknown InputIN=tun0 OUT= MAC=
I noticed in the syslog was registering the creation of the TUN interface.
Any suggestions on what I am missing to get the logs to stop screaming at me when I am using VPN?
