Yeah, get your new OPNsense device fully set up through the guide, and it will act as a router and firewall. Once it’s ready to go, plug it in with ethernet to the Verizon router (with the ethernet connected to your OPNsense going into the WAN port) and make sure it’s picking up internet from the Verizon router. Once you’re sure it is, then go into your Verizon router’s settings and turn on bridge mode. The internet should auto-reconfigure for your new router to grab the IP from the modem by passing through the Verizon router.
If for whatever reason this doesn’t work, you can regain access to the Verizon router by doing a factory reset (as you won’t be able to view it’s settings as it no longer has an IP on the network in bridge mode). So don’t be afraid of it, worst that can happen is a factory reset. Just back up your settings beforehand (either manually writing them down or exporting a config file) so you can restore them easily.



Yes, consumer routers are much lower powered because they’re built to be a router so they can simplify it to the basics needed just for routing. The trade-off is that most off-the-shelf consumer routers don’t support V-LANs.
The person you were responding to notes they have a Mikrotic device, which is one of the most popular series of devices for people to put OpenWRT on.(EDIT: Memory was foggy it’s actually devices with MediaTech CPUs is what I am thinking of) The major downside here when it comes to exposing devices to the internet is you lose the strong firewall. Part of why the OPNsense firewall is stronger than what a consumer firewall even with OpenWRT on it is because it isn’t just built to be a router, and being much beefier allows it to handle much more complex firewall rules and things like packet inspection or intrusion detection. OpenWRTdevice has a basic firewall which will do the job, for sure, but I am definitely on the side of using something a little bit more powerful for more firewall features and options. You’d probably still be relatively safe with OpenWRT/, but the low power of the devices may make them less robust depending on how many users you plan on having, in which OPNsense’s beefy nature makes it more robust for more data passing through.EDIT: Those Mikrotik devices OP is referring to are different than what I was thinking of, but they also have a good price point and are dedicated routing appliances thus lower power draw (many of them support Power over Ethernet). Their OS isn’t as open as any of the others though, however it offers a full featured enterprise grade router OS. A good choice for someone who isn’t as savvy off the bat, although you lose the powerful firewall.

They also have a demo of their RouterOS which seems like it’s very full-featured: https://demo.mt.lv/
