Can't Route LAN Traffic Behind Tinc Network

I have a 4 Node Tinc VPN setup with 2 nodes on my LAN and the other 2
outside the LAN in the cloud. Everything has been working great for about 5
years now, until today when I decided to move one of the nodes to another
box. I basically, copied over the /etc/tinc folder to the new server and
also moved the /etc/network/interfaces file, so that the new server was an
exact mirror (more or less).
But I think I may have forgotten something because while all my nodes can
ping each other using the VPN IPs (i.e., 10.9.0.x), I can't seem to ping my
LAN (i.e., 172.23.6.x) from any of the external nodes.
At this point I'm unsure of which information to provide in order to elicit
some assistance, however, below is the routing table of one INTERNAL and
EXTERNAL node. I basically want to be able to reach the 172.23.6.0 network
from any of the EXTERNAL nodes - any assistance would be highly appreciated.
Thanks.
