RFC 2136 Client fails to update more than 1 record
I added a single RFC 2186 Client (name1.mydomain.com) and verified it worked. DNS was updated and 'cached IP' was green.
I then added an additional entry (name2.mydomain.com), all other parameters the same. It did not work - client page showed N/A.
System log shows 'Not updating name1.mydomain.com A record because the IP address has not changed'
System log shows 'Not updating name2.mydomain.com A record because the IP address has not changed'
Edited entry and presses 'Force and Save update' - same problem.
Manually ran rc.dyndns.update - same problem and log message.
There was only a single /conf/dyndns_wan_rfc2136_'name1.mydomain.com'_ns.mydomain.com.cache
I had to delete that file (note: there was no name2 file). Then it worked.
