I'm hoping this is a firewall issue but I figured I would check just in case I'm looking in the wrong direction.

I setup a pair non-CA replicas today and as far as I could tell everything seemed to be okay but I noticed that when searching via the web ui on the new replicas it would take 2 minutes to return information.  

I the logs I noticed this time out error which is what I assumed was the culprit:
[Wed Jun 07 14:48:31.155444 2017] [:error] [pid 14384] ipa: ERROR: ra.find(): Unable to communicate with CMS ([Errno 110] Connection timed out)

I can see in tcpdump connections over ldap and 8080 which should be open between the two and I wanted to verify if there should be any other ports open that aren't covered in the install instructions or maybe something I missed (7389 perhaps because its 4.x to 3.x communication).

Also I was hoping to cut down traffic across the network since the new servers are in the EU and the old ones are in the US.  Are there any tips/instructions on doing something like this if its even possible?

# firewall-cmd --zone=public --list-all
public (active)
  target: default
  icmp-block-inversion: no
  interfaces: ens224
  sources:
  services: dns http https kerberos kpasswd ldap ldaps ntp snmp ssh

Thanks!
