Yes it is. PITA to work within your own network.

I run a DNS server for this purpose.

I wanted a taskbar button for Navidrome at work. This is so I could quickly find my music in between the several open Firefox windows.

As the IT admin, I could’ve installed this. But I knew I REALLY shouldn’t. It needed administrator rights, and I had no idea how secure it was.

So instead I used Brave for Navidrome PWA. Brave was installed as local user, so it couldn’t bring down my entire organization if it got my password.

Now I’ll be able to switch back.

You can do DDNS for free, using a client app on your server, rather than router.

I use cloudflare-ddns
