I run opnsense as a VM and have done for maybe 5 years now, moved across 3 different sets of hardware.

I DO have a hardware router under the ONT for if / when I feck up proxmox.

Snapshots are great when you start to play with the firewall settings or upgrades

I had/have no trouble here

I’ll be intrested in the results of this thread

I’m wondering if you have an incorrect gateway set or default route

also, what ports on both routers are connected? are they both using “WAN” for their uplink?

As said look at DHCP clashes or " Wall -> Ethernet Splitter -> PC Under either"

What do you mean by this? The ones I know of will drop the connection to 10mb or 100mb and will on work on both “halves” at the same time*

you could probably find cheaper with more to do more

I see you mentioned the free Oracle cloud servers, they are not simple to use like many cloud VPS. But if you wanted to go down that route then if you get a full account with a CC on file then you can normally get the ampere instance (still free)

I say go with proxmox on the n100 (I use it), there are alternatives kvm/QEMU managers that I heard good things about as well (namely Incus https://github.com/lxc/incus )
