Primary DNS zone transfer over different port issue #956

Open LilyTheOtter opened 5 days ago

LilyTheOtter commented 5 days ago

Based on the following reddit post: https://www.reddit.com/r/technitium/comments/1do6mxu/primary_dns_zone_transfer_over_different_port/

Summary: For corporate reasons we need 3 servers in 3 locations, 1 location will have Primary DNS zone and can't go over port 53 so 8053 has been chosen. Zone transfers with port 53 work fine but when changing to port 8053 self initiated zone transfers from notify etc. stop working but clicking resync in the GUI works fine.

Test setup:

1 Primary server running on Debian 12.5 with IP 10.13.10.65 1 Secondary server also running Debian 12.5 with IP 10.13.10.66

Primary zone settings corp.test: Port of DNS server: 53 Zone Transfer: Only specified name servers with 10.13.10.66 specified Notify: Only specified name servers with 10.13.10.66 specified

Primary zone settings corp2.test: Port of DNS server: 8053 Zone Transfer: Only specified name servers with 10.13.10.66 specified Notify: Only specified name servers with 10.13.10.66 specified

First test: So in the first test when the Primary server port was still 53 I added the Primary zone test.corp on the Primary server 10.13.10.65, in the zone settings I allow zone transfers from 10.13.10.66 and also notify 10.13.10.66. I go on the Secondary server 10.13.10.66 and add the secondary zone test.corp pointing to 10.13.10.65. This works perfectly and when I create a record on the primary DNS it gets updated on the secondary. Perfect.

Second test: In the second test I changed the port of the DNS listener to 8053 and added the Primary zone test2.corp on the Primary server 10.13.10.65, in the zone settings I allow zone transfers from 10.13.10.66 and also notify 10.13.10.66. I go on the Secondary server 10.13.10.66 and add the secondary zone test2.corp pointing to 10.13.10.65:8053. It adds the secondary zone just fine, but when I add a record on the Primary zone it doesn't update on the secondary server and eventually gives a "sync failed" status instead of "enabled". Clicking the resync button gives a successful zone transfer but goes back to the same problem. Logs are as follows:
