the opnsense is a B-router

Yes, I'm running opnsense in Hyper-V, the LAN NIC is 2 GBs aggregated in windows server
I'm using two dlink DUB-1312 aggregated. in Untangle was working fine for the last 4 years it was showing 2 GBs NIC but in opnesne the lan and wan showing 10 GBs, I'm not sure if this is a driver related issue? or it is not designed to recognize 802.3ad protocol?     

Why I'm getting this message?

   [100716] <Error> -- bridge0^: error reading netmap data via polling: No buffer space available

how to solve it!!!

for those who face the same issue, i have managed to fix it.

at first you required to enable Promiscuous mode and then select all interfaces that you would like to monitor in Listening interfaces, select the bridge interface in the WAN interfaces option (NetFlow).

everything will work fine.

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!

i have fixed the issue, you require to enable router advertisement guard in Hyper-V 

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

How to setup Opnsense as a secondary firewall.
im moving away from Untagle and i want to use the same setup.
