i have setup opnsense in hyper V acting as Transparent Filtering Bridge "B-Router".
everything is working fine, when enabling netflow i loss network connection, everything goes down, there is no traffic downstream of the opnsense.

i have to disable the option and restart the opnsense again. how i can solve this issue, i need to export netflow to external app!

General Discussion / Transparent Filtering Bridge

Currently I'm using Untangle NGFW and deployed in Hyper-V
the LAN interface is set to source and the WAN is set to destination and in the firewall the LAN is set to bridge. for the last 4 years the setup served me well

in OpnSense i have used the same settings in Hyper V and followed the instruction mentioned in here (https://docs.opnsense.org/manual/how-tos/transparent_bridge.html) but i can't ping the upstream router there is no internet, i have all options in the virtual switch of hyper V (Source, destination and non).

the mac address for the LAN and WAN are correct between the Hyper-V and Opnsense
