OpenVPN internal network unable to reach remote offices
I have a main office running OpenVPN on Untangle v9.4 (I know, but they don't want to spend the money to upgrade and reconnect all of the offices) The remote offices are all on different subnets, and I have no problem reaching the main office by IP address or hostname from the remote office computers. From the main office, I am unable to ping or communicate with any of the remote offices. There are no issues with the main office connecting to the internet, but I am unable to communicate with the connected networks. The OpenVPN connectivity at each office is using a Ubiquiti Edgerouter-X with the config file imported and I use my laptop to support the various offices via a software client OpenVPN connection. When I connect to the OpenVPN server at the main office using my laptop, I am able to ping, use RDP, whatever, I can even use NSLOOKUP from the DC in the main office as the server and get the IP Addresses for the systems in the remote offices. Trying to run a tracert from the cli on the DC server in the main office gives me a first hop that is the LAN address of the Untangle box, but times out on every other hop. This looks like a route issue to me, but I haven't been able to add a static route in any form that allows me to communicate with the remote networks. Help!

Check firewall rules. Routing should be ok as routes will be installed when the VPNs come up.

The firewall app was not installed. The untangle box is in bridge mode. I am able to ping the remote networks connected using OpenVPN from Untangle, but not from anything on the local network. I have also noted that the IP for the DHCP server on the openvpn interface when I am connected from laptop does not match the static route interface for the OpenVPN network that I see in static routes, but adding the IP address to static routes does not change anything. I added the firewall app and set up rules to allow me to get to one of the remote networks, but I am still not able to ping any device on the remote network. I am also unable to ping the local address of the OpenVPN network 172.16.0.2 or the one I see as a DHCP server for my connection 172.16.0.6 from the local network, though I can ping the 172.16.0.x host at the remote connection from my laptop outside the local network.
