Dynamic DNS on freedns.afraid.org

[mav]

I thought I'd mention this, having run into it this morning when setting up a new system & this is a much easier & safer approach (I think) than that described in other forum threads like

https://forum.opnsense.org/index.php?topic=36994.0

as it doesn't require you store any credentials, and you can revoke the update token at any time on the FreeDNS control panel.

On the freedns.afraid.org interface:

• Navigate to the new update interface https://freedns.afraid.org/dynamic/v2/
• Make sure "Randomized update token" is the selected option.
• Copy the URL listed there: it'll be something like http://sync.afraid.org/u/blahblahlongcharacterstring

Then, in the dynamic DNS panel on opnsense:

• Make sure backend is 'native'
• Create a new item and set the following
• Service: custom
• Protocol: Custom GET
• Server: Paste in the URL you copied from the freedns.afraid.org panel above
• Hostname: this is required by the form, though I don't believe it's used, I set it to the domain I'm trying to update.
• Make sure to set "Interface to monitor" correctly
• Save and then apply settings.

Give it a minute or two to update, and you should notice the additional values in the Services: Dynamic DNS Settings page appear.
