Pushing DHCP Options when using Proxmox SDN

[Notavi]

I have a couple of simple Zones, each with a VNet and Subnet configured. For each of these, I want to push some additional configuration via DHCP (primarily default routes, but may want to add WINS or other DHCP options later).

To add some additional context to this - I'm planning on using an OPNSense VM to act as the firewall between my virtual subnets and the LAN.

Because Proxmox DHCP is using the .1 address for my subnets, I have the OPNSense available as .2.

I'd like the default route to point to the .2, but changing the gateway in the subnet config seems to also change the DHCP IP. I've already got Proxmox talking to PowerDNS so I want to keep using its DHCP & IPAM solution (I'm also not sure I'll be able to do all of the things I want to do with Unbound DNS, but PowerDNS should be able to do it).

The configuration files for dnsmasq are located in /etc/dnsmasq.d/{zone_id} you can add custom configuration files there (not edit, they will be overwritten on save). Then you can add custom dhcp-options as described in the dnsmasq configuration [1].
