That's a bug in the validation routine in the Opnsense interface. I THINK it's already been taken care of, but not yet released. I manually patched mine to allow the API token I use for GoDaddy whilst I am playing with DDclient and Godaddy,

I Agree with above comment. I use AWS R53 and Tunnel Broker(HE.net) which are built in options in the old dyndns client. They don't exist in the ddclient settings. It doesn't have to be an all in one in my opinion. I've seen projects for aws53 updates that could maybe be worked into a new module. For example: https://github.com/crazy-max/ddns-route53
In terms of alternate dynamic dns clients, was the inadyn client ever considered? It appears to be under active development, and has many predefined providers along with the ability to add custom providers.
