We have an XG310. We are currently migrating our Exchange server from 2013 to 2019. I am trying to figure out how to change our firewall rule for OWA to point to the new server.
I go under "Rules and policies", IPv4 and we have a rule created for OWA. After that I have no clue.
Our previous network admin left a sheet to change settings in our internal DNS to change "mail" and "webmail" to point to the new server, could that be how it is configured?
