it is unusual but not prohibited to run a WAN in a single subnet.

You might suggest to your comms guy that he consider running the WAN as a
number of routed subnets.

Oh, to hell with being judicious. Get your comms guy back in and tell him to
fix it.
He has your HQ network at 10.0.0.0/8 and the remote at 10.10.3.0/24.
The two networks believe they are independent networks of a different class.

eg. the network address at HQ is 10.0.0.0, the broadcast address is
10.255.255.255. The remote LAN's network address is 10.10.3.0 (which is a
host address at HQ) and the broadcast address is 10.10.3.255 (also a host
address at HQ)

You don't happen to be in Sydney Australia, do you?
