Routing pfsense dns server dynamic DNS updates through VPN tunnel

[Jrp 0]

I am using pfsense as a DNS forwarder to send queries across a site to site VPN for resolving.

This works fine for clients.

I have implemented dynamic DNS updates from the client dhcp requests.

These updates go out the WAN port using the public ip as the source.

I need these updates to be sent over the site to site VPN to our internal DNS server.

How can I route this traffic over the VPN?

What sort of VPN is it?

Are you using Unbound or DNSMasq?

If it's IPSec and you're using Unbound you probably need to do this:
