Title: Auto detection of WAN port does not work
Post by: Karla on July 27, 2026, 01:26:25 PM
Since some time, the auto detection of the WAN does not work.

I have a Fritzbox 7530 as modem / router.

Would please provide more information? Where on the Fritzbox do you connect the OPNsense box, LAN or DMZ? Is OPNsense WAN usually getting a Fritzbox LAN address (192.168.178.xx ?). Do you set a static WAN to get it working? Have you changed anything on the Fritzbox? What OPNsense version are you using? OPNsense as a VM or a physical device?

The setup is at follows.

Fritzbox 7530 -> OPNsense (at Lan) -> Fritzbox 4040.

The IP adress of Fritzbox 7530 is 192.168.178.1 with DHCP and DNS server.

Actually I am using OPNsense 26.7.

OPNsense runs on physical hardware - not VM.
