What ports does the local FOG server use when imaging?

I’m imaging using FOG 1.2.0 on CentOS 7 and our environment needs to be pretty locked down. It is working with SELinux enabled and I’m using IPtables as well. I opened the firewall using IPtables to accept any UDP and TCP on the entire subnet we’re using. Before I had done this, the imaging process was quite slow, now it happens in 8 minutes or so which is fantastic. The problem is, I’m trying to only allow it on certain ports only. I watched with netstat as it was imaging and saw port 2049 on the FOG server, but I wanted to be sure as to which port(s) the FOG server uses when deploying an image. Thanks all and I appreciate any and all feedback!

It’s old… but it’s there.

I would think you can’t really “make” fog use one port for the actual imaging process (via NFS) because it’s going to use open ports to separate traffic streams, esp. for multicasting.
