npub1slstdcssgln3r6t6wedquf77zraxyarveyacae6ny4v4jwz679dsvdyr9t (npub1sls…yr9t) not much experience with pfSense, but is your ISP/modem blocking the router? Years ago when I installed Cisco RV320s, we would have to clear the cache on the modem by unplugging for 5 minutes, or sometimes even call the ISP to help.
Ubiquiti Unifi gateways didn't have that issue.
