OPNsense not showing on ARP in Bridge Mode

[JAVEWS]

Hi all,

Noob here. Just installed OPNsense yesterday and have gone back through the bridge mode instructions 3 times and I cannot reach OPNsense on my network. . Modem’s IP is 192.168.1.1 and my network and the OPNsense appliance  (Protectli) is on a static IP address of 1.92.168.1.10.  Modem is in bridge mode and OPNsense and the "allow all rules" seem to be working as I can get out to the internet and traffice can come back to me. I simply cannot access OPNsense.

Network: (All have static IPs)
Netgear Nighthawk Router
TP-Link 24 Port Managed Switch
Synology DS423+


I can access internet but cannot connect to modem’s gui. Ping is returning request timeout. Please help 

Alibi: The whole reason I've built my home network is to help me learn the skills necessary to eventually crossover to the tech industry...I would really appreciate any help in learning/troubleshooting/fixing this issue.

I assume you've set the required tunables according to those instructions ?

If so, the next most overlooked issue is to still have IP address assignments directly to the interfaces (Bridge Members) instead of the Bridge device itself. So check if the 192.168.1.10 address is assigned to the Bridge device, not the raw interfaces (leave them unnumbered, ie no/empty IPv4 or IPv6 config).

My 2 cents, don't start your network/security journey with a transparent Bridge, but just use traditional plain-old-routing and work your way up. Bridges have some quirks and caveats that will distract you from the essentials, but YMMV.
