If you want to make the same change on the remote server that you made
locally, can't you use nsupdate again but point it at the remote server?
Or is there something more complicated going on?
Use ddns-keygen to create a TSIG authentication key and add the key to the
allow-update ACL on the remote server.
(You can also add your own TSIG keys to allow remote control with `rndc
-s`, but it sounds to me like rndc is a red herring.)
There's also my `nsdiff` program https://dotat.at/prog/nsdiff/
which can make a zone on a remote server look like a local zone
file using nsupdate.
