Description
Maintainer: @feckert
Environment: arm, wrt3200acm, 19.07.6 (ROOTer)
Description:
I have an internal DNS server on which I would like to be able to update an A address from a remote OpenWRT router.
This DNS server can be updated through a port different from 53, however the bind-nsupdate service has no provision for specifying which port to use.
I would like to have update_nsupdate.sh and dynamic_dns_functions.sh modified to allow using a port different from 53.

Research direction
Start by reading update_nsupdate.sh and dynamic_dns_functions.sh to trace how the bind-nsupdate server address is assembled and passed to the update command. Confirm how the existing configuration supplies the server, then make the port configurable without changing the default behavior. Done means updates can target a DNS server on a port other than 53.
