22.1 Production Series / Can't start AdGuard plug-in after opnsense upgrade
« on: February 07, 2022, 07:37:17 pm »
Is it just me or others can't start AdGuard after opnsense 22.1 upgrade too?
AdGuardHome (os-adguardhome-maxit) from https://www.routerperformance.net/opnsense-repo/ worked fine immediately after upgrade to Opnsense 22.1. But after a couple of hours, adguard crashed and I can't start it anymore.

How to read/analyze a firewall plain text log?
I am struggling to understand my firewall plain text log.
I didn't find any satisfying documentation as well.
Please help me understand the following example line:

Code: [Select]

General Discussion / Source & destination network options of firewall rules
« on: August 25, 2020, 08:34:47 pm »
There are some network options available as a source or a destination while creating firewall rules:
Networks
  • any
  • This Firewall
  • LANx address
  • LANx net
  • Loopback net
Thous terms may sound obvious for some people, but I am struggling to grasp their true meaning.
For example LANx address and LANx net networks sounds the same for me.
Can anyone point me to some documentation clearly explaining these options?

General Discussion / Ways to isolate LAN interfaces...
« on: August 23, 2020, 09:30:24 pm »
I am a complete newbie at Opnsense. It is my first post here.
I have a WAN and management LAN interface.

I need to create several additional LAN (opt1, opt2, optN) interfaces isolated from all others except for a WAN. In other words, I need several LAN interfaces that have internet access but can't access each other.
So far I came across the following solution: https://www.reddit.com/r/OPNsenseFirewall/comments/bm4b6w/outgoing_firewallrules/emweuyc?utm_source=share&utm_medium=web2x&context=3

Is it there any other good solutions for such a "challenge"?
