VLAN Issue
-
Technically you should not have to configure any rules, as pf should deny implicitly. Could you post your current rules, the contents of /tmp/rules.debug, and the output of```
pfctl -sr -
My rules for my guest VLAN currently look like this:
Make sure that you flush your states (I prefer to do it in command line just to be safe with pfctl -F state) and verify that your pfctl -sr output is what you expect it to be.
-
Thank you timthetortoise :)
Its working :)
I will setup a lot of vlans and I have to do so much rules per interface.
Why something changed in the new snapshots of pfsense 2.1 ? Before everything between the interfaces was automatically blocked without any rule.
-
I'm having the opposite issue, LOL! I have my setup set to allow OPT1 to any and I can't connect to IP addresses on the LAN interface. em0_vlan69 is LAN em0_vlan15 is OPT1
-

Hasn't changed ever, a new interface has no rules which means no traffic allowed initiated from that interface, same as always. Initiated into that network is controlled by the source interface's rules.

No CMB, there's something seriously wrong in the latest builds. The same rules that USED to work fine don't work anymore on VLAN's to allow traffic between interfaces. I can't communicate with the LAN (which is a VLAN) from other interfaces (including the OpenVPN interface). Something's definitely seriously broken - this always used to work.
-
Can you post your /tmp/rules.debug and screenshots of the gui(or config.xml) to see what is happening htere?
-
I got it to work by adding a new rule I don't think I needed before. I added a rule on the LAN interface to allow ANY to LAN SUBNET. I don't think I had a rule like that before but I do now realize I may have had allow any to any. I don't recall, but should a rule like that be needed on the LAN side? Thank you for your help Ermal. It definitely seems something's changed slightly.
-
It technically shouldn't be necessary. Established connections should be allowed through. I noticed the same thing with my OpenVPN tunnel and chalked it up to a misconfiguration on my part. I'll have to try setting a rule for it today.

I wasn't just noticing it on the OpenVPN but also on another VLAN. Something seems to have changed in the default rules and it now needs explicitly stated. What would be most helpful Ermal and I will get it posted right away.
-
I'm not noticing that, to be honest - my rules allow LAN1 to LAN2 on the LAN1 side, but not the LAN2 side, and it works correctly (can pass traffic from LAN1 to LAN2, not vice-versa). I have no rules regarding LAN1 in LAN2, except to disallow ingress traffic on LAN2 to LAN1 (again, already established connections should not be affected). These could be completely different issues, but it's very odd nonetheless.

Yes, also limiters are broken I forgot to note that I found that - with in/out limiters set up on my VLAN's (yes, in is masked by source IP and out by destination IP) no traffic passes whatsoever. Something is definitely seriously broken in recent builds, could it be something that is just one thing that relates to the parsing of firewall rules? Sadly, I have no way to tell when it broke since I hadn't upgraded in 60 days and when I did, I wiped the box and started over.

If you refuse to provide feedback i will just mark you as a troll an lock this subject.
Decide on your own if you want to continue and give feedback or just troll around.

What on earth are you talking about? I said above - given what's going on, what would be most useful? I'm happy to send you anything you need to help troubleshoot!
-
I seem to have got my limiters working again, it seems that was an unrelated thing (I forgot limiters have NEEDED defined schedules for quite a long time now, forgot why they do).
What files would be useful to help determine why I'm needed extra rules to communicate between VLAN's? I'd be happy to send anything you need or provide access to the system if I'm not able to get it.

Have you already provided the requested information:
@ermal:Can you post your /tmp/rules.debug and screenshots of the gui(or config.xml) to see what is happening htere?
If so, where?
-
No I haven't because the forum doesn't let you post files with those extensions. I'd be happy to email those files to Ermal (or other devs) though!
Edit, I just tried posting screenshots of my rules but the forum just timed out and didn't let me post those either. Today, I'm having issues connecting to one of my WAN interfaces but that may simply be my Internet connection at work blocking it - I have a HORRIBLE Internet connection here.
-

It won't stop you posting the contents of the requested file(s) within a reply (within a quote block or code block to distinguish the contents from commentary).

Good point I didn't want to flood the forum but if that's the best way to get those to you guys here they are. Also, not being able to access one of my WAN interfaces was just, as I suspected, my work blocking the IP address. So the only issue on-topic to this thread seems to be the communication between VLAN's, except, instead of being unable to block traffic I had to specifically allow it on the other interface. Here are the files Ermal requested:
