My first post here and I have been trawling for any information on my problem and have not found any. (Does not mean they are not there - just I cannot see them perhaps for looking).
In simple form, I can set rules on the pfBox and kill 99% of traffic without any dramas. Ping IP, resolving domain names sending and receiving emails all stop. BUT! I cannot block Minecraft and some other games - ARMA II on Steam for example. Minecraft works on Java so is there something different I ought to be doing? Even removing the "Default allow any to LAN" rule does not stop it from talking to servers.
I created "floating rules" aimed at the specific IP of the machine my son uses (when he ought to be studying - yeah, there is the reason) and my own so I can check something is being blocked. Also WAN side but I honestly would have thought selecting the IP (or even alias for his two machines), then selecting 'any' as the protocol and 'any' for the destination ought to have stopped it.
LAN topography is AG300 [192.168.2.1] => pfSense BOX [192.168.1.1] => NetGear 8 port switch then to all machines. [Win, Linux, Mac, PS3]. Logs show that the rules are applied and testing proves that they are. All machines loose access but all machines running MCraft still run it and it still talks to the servers.
Short of stopping the pfBox or removing the cable or taking the machine off him [not an option as he uses it for school work - but other means are still available] I am stuck.
Any assistance would be much appreciated. All else with pfSense seems to be flying nicely.
I shall keep working on it and post when / if I find a solution!
