All working!

I had to make one small change. I suspect the version on OPNSense in the guide is an older version. I didn't have an option to auto detect and uptream gateway on the WAN interface configuration.
I had to add the IP of my broadband WAN router in (not sure if this the correct way) as an entry in System > Gateways > Configuration. I was then able to select that entry in the OPNSense's WAN interface section "IPv4 gateway rules".

Thanks for guides both. :)

Thanks meyergru, I'll review that post too.

Thanks both, good points!

Have a managed switch and have a fairly mature homelab. Previous I used the same VLAN as my "home" network traffic to get out the internet. I've already tried add routes the BT router but it doesn't allow me to add routes for network address not assigned to it's own LAN port.

I'm not particularly fussed about the double NAT issues as I am not hosting any internal services that will require port forwarding. Is NAT (as suggested in option 2 of meyergru's post) something that needs to be explicitly configured on OPNSense, I thought it was enabled by default?

I'll review the link in your post too cookiemonster. Thank you both!

Hi Forum,

I've just built my first OPNSense appliance and needs some pointers on a very basic setup. I'm chained (due to rural infrastructure) to a BT Broadband HomeHub (192.168.1.0/24 - LAN), and I'd like my Proxmox vms (192.168.2.x/24) to be able to get out to the internet using a a different VLAN. Am I correct that I would need to configure the following on the OPNSense appliance:

- WAN Port: Set IP address to 192.168.1.x/24, allow private networks
- LAN Port: Set IP address to 192.168.2.x/24
- Add a gateway address for the LAN IP of the broadband router?

Would  need to do anything else?

Thanks all for you help and suggestions in advance!
