hyper-v replica from production to DR

Hi

i have production hyper-v cluster with VMs and DR hyper-v cluster setup , between the hardware firewall hyper-v replica enabled and open port (80.443.135.139)-  replication is successfully doing

but once the planned fail over start  its not finishing (it showing failover in progress long time )

network administrator monitor the traffic saying many deny traffic is there.

my environment is very tight by firewall,

i need to know what are the traffic(ports) we have to open in firewall between the cluster.
