So the subnet mask is got from the device handing out dhcp. Not 100% sure but on my android the subnet mash for wireguard is as /24 set on the device and also matching in the wireguard settings in opnsense. Opnsense is very very powerful, I would watch a few videos on YouTube about subneting, wireguard routing & dhcp. Its gonna be quite the learning curve (or could be)

glizzyguzzler@lemmy.blahaj.zone 1 year agoWhere would I set the subnet mask?
I do not understand how to apply most networking concepts effectively - I only run Opnsense to get a router that has actual software updates, not because I now how to use it (no experience with networking otherwise).
In WireGuard I specify the 10.0.66.XX subnet directly without DHCP. In Opnsense, I’m not sure where to look and searching for it didn’t help illuminate anything obvious.

Who knows indeed, I’m beginning to suspect that it was able to connect via the internet (and that stopped working) and I just never noticed so the VPN was a superfluous extra step.
But I did try in the [Peer] definition setting the allowed IPs to: 10.0.66.10/16 instead of 10.0.66.10/32, which should expand the allowed range to 10.0.69.XXX. Alas, that did not work.

Both devices need the same subnet mask, otherwise only one can see the “extra addresses” but in my opnsense I think I and to add some firewall router between LAN & WG0

Setting the WG [Interface] range to 10.0.66.0/16, along with the [Peer] to 10.0.66.10/16, and the Opnsense DHCP range in Interfaces->LAN to /16 made no connection to the internet or local occur.
This feels like banging rocks together hoping for fire - not for me (but maybe reading stuff for a bit will help, maybe)

Check your firewall logs (Status -> System Logs -> Firewall for pfSense, can’t remember for opnsense). I’d suspect you might see blocks from 10.0.66.x to your Playstation.

I don’t see any - but I guess it makes sense, the Opnsense computer isn’t involved by design in local network activity. The Opnsense comp goes to a switch that all other LAN also connect to, and I assume the switch routes so the Opnsense comp connection doesn’t get bottlenecked. I indeed forgot that’s how it worked till now - thanks for the suggestion, helped me internalize a bit more infrastructure at least!
