General Discussion / Re: LAN GW is using WAN IP?
February 16, 2026, 11:36:13 AM
Thank you for the insight, Patrick!

I certainly don't have another router being used on my network. I'm wondering why this was added in the first place, and I have no recollection of creating the LAN GW myself. Is there another place this is configured besides this screen, or is the only thing I must do is delete/disable the LAN GW configuration?

General Discussion / LAN GW is using WAN IP?
February 16, 2026, 10:44:17 AM
Hi there,
I have a question about an apparent misconfiguration for my Gateways. According to OPNsense, it states that my LAN GW is incorrect, which I promptly tried to switch to my LAN's IP of 192.168.2.1 to fix the problem. After doing that I was disconnected, and had to reset back to 192.168.1.254 as the LAN GW. What is the problem here? Important note: I'm behind a Double NAT, there's nothing I can do about it. Any suggestions? Thanks

LAN Range: 192.168.2.1/24
WAN Range: 192.168.1.1/24

@coffeecup25 My router, which is no more than a mini PC with an added Ethernet port, needs VLANs because of only one LAN Ethernet port. I haven't had any instabilities so far with the VLANs (fingers crossed), I'm curious what causes that.

Thanks so much for your help, in advance. Firewall rules are quite daunting to me, but I believe (and hope!) that my understanding is getting a bit better.

Here's my Guest VLAN, along with the added Floating Rules.

Here's the Admin VLAN, with a few restrictive rules:

Here's my Home VLAN:

I have to access the WAN net because I'm behind another NAT unfortunately. Should The Admin Aliases to Firewall be placed in the Floating, or are they best left specifically for the Admin VLAN rules?

Hi everyone,
I'm fairly new to tinkering with firewalls, so I'm bound to make lots of mistakes, so I'd thought I'd might dip my toes in by creating a guest VLAN and trying out some Rules, and wanted to get some feedback. I have a screenshot of my Rules attached. Anything to look out for, missing, general advice? Are there any must have Rules for guest networks over others? Did I make any mistakes? :)
