A proposal for a change in dynamic DNS interface of GL GUI

It would be nice if dynamic DNS in gl-inet routers could allow users to choose an interfaced used for updating the DNS record from the GL GUI. As I understand, right now the router uses the default route to determine the default gateway which may not be always what is really needed.

As a temporary workaround, to make sure that the DNS record always points to WAN IP address (for example) I use curl as a follows:

/usr/bin/curl --interface eth0 https://freedns.afraid.org/dynamic/update.php?ZZZ

as a cron job.

Just install luci-app-ddns to manually set up your own DDNS server.
