Openfire server to server

Good day 4 all

I am having difficulty operating the communication between two Openfire servers.

My scenario there is an IPSec VPN and both places use the same Active Directory and DNS zone. etab.local <—> 12poa.local

chat.etab.local <----> VPN <----> chat.12poa.local

192.168.0.0/24 IPSEC 192.168.3.0/24

Internally the two servers can resolve names normally.

But active in both settings and nothing happens.

I created the SRV type entries in both DNS zones

Is there any limitation to share the same domain on both sides? remembering that on each side separate AD users by different groups.

grateful

Any tips?
