I've got two virtualmin servers, each at seperate locations. I've got 5 domains hosted on server1 and 2 domains hosted on server2. Both servers are the master for the domains hosted on them, and I've set the opposite server to act as a slave for those domains.
I added a domain to server2, and all the dns works and the zone file transfers seamlessly (deletes upon virtual server deletion changes upon update etc), and from what I can tell propagates correctly to server1 however, when i add a domain to server1, only a blank zone file is sent over to server2. And having left this for several hours, and even done a forced rndc update I can't seem to get the zone files to send from server1 to server2. Any ideas where to even start troubleshooting?
