I am running a VPN server but need to block illegal torrent downloads. The VPN plugin is provided by safesrv.net I have had updated Iptables prepared but I am interested in feedback from anyone who has experience with this.

Our updated iptables are below:

iptables -I INPUT -p udp --dport 1024:1193 -j DROP
iptables -I INPUT -p udp --dport 1195:1644 -j DROP
iptables -I INPUT -p udp --dport 1647:65534 -j ACCEPT

## Allowing all neede ports for OpenVPN L2TP PPTP and RADIUS
iptables -I OUTPUT -p udp --dport 1812 -j ACCEPT
iptables -I OUTPUT -p udp --dport 1813 -j ACCEPT
iptables -I OUTPUT -p udp --dport 1701 -j ACCEPT
iptables -I OUTPUT -p udp --dport 4500 -j ACCEPT
iptables -I OUTPUT -p udp --dport 500 -j ACCEPT
iptables -I OUTPUT -p udp --dport 443 -j ACCEPT
iptables -I OUTPUT -p tcp --dport 1723 -j ACCEPT

## Drop torrents
iptables -A OUTPUT -p tcp --dport 6881:6889 -j DROP
iptables -A OUTPUT -p udp --dport 1024:65534 -j DROP

## Set more radius (alt) ports

iptables -I OUTPUT -p udp --dport 1645 -j ACCEPT
iptables -I OUTPUT -p udp --dport 1646 -j ACCEPT

## Try torrent name filters
iptables -A FORWARD -m string --algo bm --string "BitTorrent" -j DROP

## Trying forward
iptables -A FORWARD -p tcp --dport 6881:6889 -j DROP
iptables -A FORWARD -p udp --dport 1024:65534 -j DROP
