Just an FYI... I didn't post this to be mean. I'm genuinely concerned. The article didn't mention any model numbers... but SOHO routers, I would assume, includes Omada.

I would have posted the link but it wasn't allowed... Feedback on this @Fae and @Hank21

@netlabguy You can use OPNsense (I prefer OPNsense Over PF) as a gateway and leave the Omada in place. Build the Opnsense box with a LAN... Static of your network/32 with no DHCP. It needs a WAN port...

@test01 Have you checked in stand alone mode?

@X3KliixX 2 things... what you are wanting isnt possible. Like you said, use a switch before the WAN port. PFsense and a Omada router are two different animals. Its like comparing apples to a grizzly...

@loopin3 You may consider running a on prem DNS server like Pihole or ADgaurd Home server...
