The relevant module is "connlimit" and it prevents more than some number being open under given circumstances. You would have to make sure it integrates with whatever you already have in place. You can use iptables to manually set up connection limits. I would start with checking what functions your router has. That's no guarantee but it can help stop it from affecting more important traffic. Some routers have QoS functions built in that allow you to prioritize traffic based on source/destination ports.
Most other apps will only have a few connections open at once. 100+ connections open to high port numbers is somewhat telling. You could probably set up some logging to track people who have high use and/or large numbers of open connections. You could also set quotas on transfer so that people cannot use more than you set (suitable for normal work usage). You can setup limits on open connections, which torrents tend to use voraciously. You can take some steps to mitigate the effects though. Even if you only leave open only certain known ports competent users can find ways around this. Peer-to-peer traffic can be between any ports.

I've heard that some ISPs spend a lot on fancy routers that can filter packets dependent on content but even that isn't foolproof because most torrent clients support encryption to prevent packet snooping. There is no simple sure fire way to do this.

PPPS I'm also aware of just telling our users NOT to download torrents, but I just want to prohibit it entirely. explain it a bit more detailed if that's the case. PPS I'm not an Iptables/Firewall expert so can you pls. Is this the answer, so how do I do it? Thanks.
PS I've heard that it's better just to allow regular ports (80, 22, 465, etc.) then block all the rest, this way, you can prevent unnecessary ports.

help me how to block torrent downloading by using a Firewall? Or is there another "simple" way? Am I on the right path? Now, I installed transparent Squid Proxy with 2 NIC cards, it works, but workstations can still download torrents! I know Squid doesn't block ports, right? So the answer must lie in Iptables Firewall? I basically use Squid just to deny access to Facebook, Friendster, or other "unproductive sites".Ĭan you pls. No other iptables rules are configured, just the above ones.īefore in a 1 NIC setup, I blocked Workstations MAC addresses in the Router + Squid Proxy Server (Not Transparent), it worked, but some Online Java Apps didn't work and users can't send/receive email so I abandoned the method. Sudo iptables -t nat -A PREROUTING -i eth1 -p tcp -dport 80 -j REDIRECT -to-port 3128ĥ. Sudo iptables -table nat -append POSTROUTING -jump MASQUERADE -source 192.168.0.0/24 Sudo sh -c 'echo 1 > /proc/sys/net/ipv4/ip_forward' sudo gedit /etc/rc.local (to start Firewall rules on bootup) Is it really that difficult?Īcl goodsites dstdomain. Hi, I've been all around the net and can't find a "simple" answer how to block our LAN users from downloading torrents.
