Question on Firewall Schedules in pfSense 2.3.2
-
Good question, my understanding is the 'source' in this situation would be the host on the LAN, as per the rule?
The block works if applied manually and also most of the time however as I mentioned, if I modify a schedule, reload the firewall rules and reset states the scheduled block stops working and requires a reboot of the firewall..
-
Source ports are almost always random. Destination ports are almost always static.
For instance to pass connections only to HTTP servers you would pass source LAN net port any dest any port 80 on the LAN interface.
-
So you are suggesting to change the port alias to destination? Like the utorrent rule I have setup in the picture?
-
I am suggesting you make sure your rules match the traffic you are trying to match.

I tried swapping my rules around as you seemed to suggest :-\ and nothing is blocked/filtered after changing to 'destination' in the LAN tab..
Again, my configuration does work fine except when the schedules are changed.. A reboot is required to get the new schedule to work correctly.
-
Yeah I doubt that it works with source ports..
Quick google shows these as the ports.
Steam Client
UDP 27000 to 27015 inclusive (Game client traffic)
UDP 27015 to 27030 inclusive (Typically Matchmaking and HLTV)
UDP 27031 and 27036 (incoming, for In-Home Streaming)
TCP 27036 and 27037 (incoming, for In-Home Streaming)
UDP 4380.As Derelict mentions it is almost ALWAYS any for source port, dest would be the port your looking at in firewall rules. Unless your talking say active ftp session for data where the source port is 20. Or maybe in a dns zone transfer where your talking 53 to 53, etc. The cases where you would set a specific source port are few and specific. Steam would NOT be one of them.
So not sure what you think is working.. But that rule would not work.. What do you have in your steam alias??
If your saying your schedules do not work until you reboot, my guess would be you have active states open for the traffic your trying to block and your reboot flushes them. Which you can do without a reboot.

It does work, lastnight it worked as expected..

Those rules are almost certainly wrong. Based on the information available on the steam site they are wrong.
Steam might try to use those as source ports which would cause them to pass and might try different source ports when they are blocked and fail to match the proper rules.
Look at Diagnostics > States and enable logging on those rules to see what's really happening.
You can create a pass rule from the source machines AFTER that block steam rule and enable logging on it to see what's getting passed.

The rules or aliases are wrong?
If they are wrong, why are they working until I alter the schedule?
-
Impossible to answer without seeing the actual states and firewall logs.
Your alias looks fine, though I would make a TCP alias and rule and a UDP alias and rule.

So I need to create seperate TCP and UDP rules even though the firewall rule has an option for TCP/UDP for a particular rule?
-
There is no reason to pass UDP-only ports as TCP as well.

So, it doesn't matter for what I am trying to work out then… only for security, which I understand.
Have you read the complete thread?

Yes. You exhibit a fundamental misunderstanding of how firewall rules work, the ports you are trying to control, and generally dismiss anyone who tries to correct you.

Wow, anyone else have anything constructive to add?

Obviously I do not understand, hence the questions.
I have not dismissed anyone?

Are you sure the Steam ports being blocked should be source ports? Source ports are usually random to specific destination ports.
Back to your original question, as far as my understanding goes, the 'source' is the client on the LAN. Changing the ports or in this case the alias to 'destination' does not work at all.
Also, I do understand that usually source ports are random when forwarding ports (NAT) however is this the case in situations like this?
I do appreciate you responding however, you have not offered any solutions, only suggesting things are 'wrong'.
Again, first post - "As long as the schedules are not altered, everything works as expected.."
My issue was with altering the schedules and states, not with the rules themselves. I posted the rules to make sure I wasn't making a simple mistake.
I am no expert and I do read and try to work it out myself before asking for assistance.
Being a moderator on this forum, I would have expected a little less criticism and more assistance from you.. :o

Things are not as you think they are. Source and destination ports are not what you think they are.
Every time someone tries to get that point across to you you say "but it sometimes works." Reasons have been given why that might be the case.
Yet here you are saying it doesn't work as you expect. That's because things do not work how you think they do.
None of this has anything to do with pfSense. It is basic IP networking.
Here's what you do. Forget about steam. Pick one IP address and one service. A good one might be DNS queries to DEST ADDR: 8.8.8.8 (HINT: SOURCE PORT: any DEST PORT: TCP/UDP 53) Figure out how to properly pass or block that traffic from a specific local host. Once you have that down the rest will be easy.

Ok, I have created a simple BLOCK rule on the LAN tab in the firewall rules. I have assigned an ALIAS to the IP address and assigned the ALIAS to my iPad. When placing the ALIAS in DESTINATION all traffic is passed. When placing the ALIAS in SOURCE, all traffic is BLOCKED.
I have attached the working firewall rule and a snip of the logs.
-
Right. In that case you ARE filtering on the source to destination any.
