I have two domains. Example.com and internal.local
Example.com has A records that point to an externally hosted website. It also has MX records that point to my internally hosted email server. I would like to use this domain as my xmpp.domain so that JIDs in openfire match our email addresses.
I set up srv records for example.com on the external DNS to point to our firewall which forwards the ports to my openfire server. Chat and S2S works with this setup but I think I have problems with voice calls and fastpath because they are trying to resolve example.com and are getting sent to our externally hosted website.
Do I need to set anything up on our internal dns to handle this? Or am I completely missing something. Is there anyway I can see where voice calls are being sent? Or maybe someone can provide some insight as to when and where xmpp.domain is used by the server or client.
