I am going to build a router with OPNSense (in Proxmox, on an HP thin client). I am stuck with setting up the networking (I have the Inel 4-port card). I don’t really know how to get started. Right now my device has one LAN cable going into it, and my consumer router is doing everything. I can set up a bridge for the other ports, but what IP address will I use for the LAN? I can’t use 192.268.0.1 because that will collide with my consumer router. Do I just take my consumer router offline while I am setting this up?I’d rather not because for sure I will get stuck and will want to look something up online. I guess I could use my phone but not the best when I am trying to see someone setting up something like this.

Silly question, I know, but I just can’t think of a clean way to get this going with minimal disruption. In a nutshell, what’s a good strategy for setting up and testing the OPNSense while it’s not actually doing any routing and then seemlessly drop it in and start working on it?

    Plug your phone into the pc and choose to trust the PC. This should share your mobile internet with your PC

    I use it all the time, when I distrohop on my laptop with a wifi card that needs to download b43 from the internet before WiFi works 🤪

    Definitely unplug existing router, else you may end up with a doubleNAT… I have a physical opnsense (without wifi antenna) plugged between my IPS router which in modem mode and another proprietary router which acts as bridge and wifi access point.
