FMC issue communicatingwith sensor

[cisco8887]

hi all,

I have pair of 4110 in another site accessed via VPN.

is there any port or specific protocol that should be allowed on VPN so FMC can communicate with the FW?

the FW registers, it goes through discovery and de registers on FMC due to communication issue.

What do you think it can be ?

The communications between sensor and FMC is via tcp/8305. Both ends needs to be able to initiate.

At the 4110 end the commuications are via the management interface assigned to the FTD logical device (not the chassis management port).
