Block Steam Downloads

KOM

Post a screenshot of your rule. Maybe there was a problem with the rule.

Where is your rule placed in relation to the others? Rules are processed top-down, so if you put that rule after the Allow All rule then it won't trigger.

I would activate the rule, clear the states (Diagnostics - States - Reset States), and then run a packet capture (Diagnostics - Packet Capture) while doing a Steam download test to see what traffic is actually passing through.

I have it at the top of the list, and sure I will do that here in about 3 hours when I get back.

Hey looks like that did the trick just fine now. Thanks for the help!

Firewall > Rules > LAN

Add new rule

Action: Block
Interface: LAN
TCP/IP Version: IPv4 (In my case)
Protocol: TCP/UDP
Source: Any
Destination: Any
Destination Port Range: 27014 to 27050

Now the issue I faced was this blocked steam completely not just the downloads. Also this does not prevent VPNs from being used to bypass the rule.

Check the firewall log and see whats being blocked, then modify your rule to accommodate it.

Also this does not prevent VPNs from being used to bypass the rule.

Well, that's pretty much the entire point of VPNs, isn't it?

Thanks!

That seemed to work generally though I have just been watching and checking the States Table to see how despite the rules and limiters the son's PC consumes 99% of the bandwidth. Modification of the Rule to match a targeted Steam IP ~ 103.2.118.3 ~ failed to have an impact. Resetting the States and hoping to see a slump, nothing. [Mind limiter is set to 2Mb IN]

Rule images attached…..names explanatory. That is a targeted one.

Perhaps I am NOT seeing the forest because of the trees and missing something silly?

pfSense:
2.2-RELEASE (i386)
built on Thu Jan 22 14:04:25 CST 2015
FreeBSD 10.1-RELEASE-p4

I realise that this is just ONE IP and have the PORTS selected similarly.

AND does Stream use 443 at all? I will assume from reading other threads that pf cannot stop encrypted traffic.

Time to hit the Submit button!!

Thanks in advance...

Dude, you've got the rule set to "Pass"… this may be your problem.
