I have setup a base Ubuntu 12.04 server, then followed the instructions here: https://raymii.org/s/tutorials/IPSEC_L2TP_vpn_with_Ubuntu_12.04.html to setup a VPN. The VPN works perfect.
I've also setup a basic Samba Share, which works over VPN.
However, I would like to use iptables to make sure that all ports are blocked to the public Internet except the VPN and SSH, and then the SAMBA server is only available to clients of the VPN. Any help would be appreciated
