Title: Strange firewall filtering behavior
Post by: nqnguyen2 on February 14, 2018, 06:51:12 am
I'm noticing some funky behavior. Has anyone experienced something similar? Do I need to reboot the firewall? Do I need to wipe clean and start over with fresh configs?

OPNsense version: OPNsense 18.1.1-amd64
Last reboot: 1.5 days ago

I'm at a total loss and I'm assuming it's my configs that's broken.

I have seen this usually after I have moved around a bunch of rules. Try a Firewall>Diagnostics>state reset
Also, if you are using IDS/IPS try disabling it to see if that is doing the blocking.

After that, if IPS is not in the way and IPs are still blocked, activate log for every FW rule you have: by default, on custom rules the logging is not ON, so it's difficult to see which packet matches a particular rule, and vice-versa.

I cleared the states but had an opportunity to reboot also. I did both and everything appears to be normal again.

Thanks for the assistance everyone.
