SSL traffic going through the port 8305 failing in Openstack infra

asked 2017-06-14 08:19:34 -0500

I have provisioned two instances through Openstack Mitaka on CentOS, one for Cisco Security virtual Firepower Threat Defense (FTD) and another one is the management platform which is Firepower management center (FMC). Both the FTD and FMC resides in the same network. when I was trying to register the FTD in FMC (for managing it). it was unsuccessful.

Both have to communicate with each other using the client/server method and it uses the TCP port 8305. when the FMC trying to connect to FTD through port 8305, it throws the ssl_error and fails. I checked the basic connectivity from FMC to FTD like ping, ssh to FTD from FMC. it was working fine.

I have created the security group to allow all ICMP, TCP and UDP traffic in both directions, but still, I was facing this issue. any help to resolve this issue?

Thanks and Regards Krish
