18.1 Legacy Series / Strange firewall filtering behavior

« 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

• Rules are as simple and basic as I can make it
• Brother's IP is in the pfTables and still in the tables right now
• Brother was able to access services from WAN to my LAN for several days
• Didn't make any changes to firewall
• Today, the same IP he's been using for the past few days doesn't get filtered by the "allow" rule but instead gets filtered by the Default Deny rule. Thus, he was blocked for some strange reason despite no changes made.

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