I can ping from the OPT1 interface in pfSense' Diagnostics/Ping page but I cannot ping that address from the WAN or LAN interface in pfSense. Is there anything obvious from the above description that would explain why I cannot see the 10.200.1 net from the 172.16 net? Here is a screenshot of the VSC config on the MSM760.

Add the allow rules for all traffic on each of the three interfaces (WAN/LAN/OPT1). This step is to ensure we have a full transparent bridge without any filtering taking place. You can setup the correct rules when you have confirmed the bridge to work properly. Go to Firewall ‣ Rules and add a rule per interface to allow all traffic of any type.

Enabled DHCP server on the OPT1 interface and set the IP range. Nothing else touched here. I just configured the general options and hit save. NAT - In the outbound section: Made sure everything was in automatic. Firewall - Added a Pass rule for OPT1 on IPv4 for any IP protocol. Source is OPT1 net and destination is Any. After all of these steps.
