I am setting up a second OPNsense install (other hardware) edited the config file from the original setup (renamed the interfaces to match the hardware)
the system starts, I can ping the gateway from my management VLAN, which means the interface is assigned correctly. Unfortunately the web interface is not accessible.
I am quite new to OPNsense, any suggestions where to look ? I would like to avoid to setup the whole configuration from scratch.
Ping is a low bar. Do you get IP via DHCP in the expected range?
Did you have a specific rule to allow GUI access or did you rely on the anti-lockout rule?
I've done several of these hardware changes (eg. passthrough to bridge under proxmox, virtualized to bare metal).
I typically boot the target device enough to see what the network device naming scheme is, then do a search/replace on the old config (e.g. vtnet -> igc) then import during install. It's been pretty seamless (apart from missing plug-ins, in particular when it's AGH configured as DNS).
