I have 3 real servers setup that are physical servers. I am trying to add some new Microsoft Hyper-V VM's to the real server list.
I have everything added, with ports bound to the virtual server (ADX) and healthchecks running.
I see the healthcheck request on the server logs. The ADX is showing the real server is active and the ports are active as well. What is odd, I see constant entries in the log as follows. Also notice the Packets Rx. I am guessing this has something to do with the Hyper-V Host, but not sure what to look for.

I think the issue is with the routing setup on the real server for the client IPs. It looks like the tcp syn is reaching to the server but server is either not replying to the syn (It is replying for healthchecks though) or the default gateway of server is configured in a way the syn-ack from server is not reaching to ADX.
The server port is going down due the reassign count feature which monitors for missing syn-acks replies for client syns sent to the server and if number of missing syn-acks reaches a threshold the port is marked as failed so that ADX can do healthchecks again and make it up.
Thanks & Regards,
