Hi,
I get SERVFAIL errors with 2048 bytes DKIM keys in static DNS TXT entries. It works fine with 1024 bytes keys so I guess the record size is the issue…
I tried increasing the DNS “Max UDP Packet Size” (made no difference) but anyway shouldn’t the packets be split automatically?
The mikrotik dns server successfully returns large TXT records for non-static entries (from the upstream DNS server), so maybe it’s a limitation of Static DNS only?
Anyone got the same problem with large TXT records in the static dns?
