Long term I can probably move 192.168.120.x into 172.19.50.x.
Short term, I'll see if the shared network will work. There is actually a
single 192.168.120.x across all sites and I'm on a project to break them up
into a subnet per site (172.19.50.x, 172.19.40.x, etc.). I'll work on a shared
network for everything and then "unshare" when I can complete the migration.
Thank you.

your issue is that your request is coming from the 192.168.120.0/24 range which
does not match the 172.19.50.0/24 range your have cofigured for your hosts.
You have two options depending on your network topology:
1. configure the relay to send from the 172.19.50.0/24 range.
2. put bot 192.168.120.0/24 and 172.19.50.0/24 subnets into a shared network.

We have to do exactly what Christian prescribed. The source network is not
controlled by this DHCP system, so the shared network includes only the network
statement, no provision to assign addresses. If you are able to carve up that
192.168 range, that should work fine for you.
