Squid guard block proxy sites

[rezzmk]

Hello, I am trying to block proxy sites, so someone connected to my Lan won't be able to use sites like hide.me to bypass the other filters I've got using shallalist. Could someone point me in the right direction?

Thanks.

If you are using squidguard, and have downloaded shallalist, you should have able to deny blk_BL_anonvpn, which blocks vpns. You could also try using OpenDNS to block proxies and anonymizers as well. Are you looking for step by step instructions?

The OpenDNS route seems to be doing well, all you need to do is set OpenDNS as your DNS, then make a firewall rule to forward all DNS request port 53 to Opendns, then another firewall rule right below to block all traffic to port 53.
