When adding a Managed Route "" under the Advanced section it adds as ""

I have followed the instructions as contained here: https://zerotier.atlassian.net/wiki/spaces/SD/pages/193134593/Bridge+your+ZeroTier+and+local+network+with+a+RaspberryPi

I have used as opposed to as per the example to align with my existing network.

Unfortunately when attempting to complete the UI step to delete all existing managed routes and add my own managed route when entering “” as the Destination under “Add Route”, although it adds the route successfully it appears as " (LAN).

Is this a known limitation or issue?

It’s working correctly because that’s just how the math works out when calculating network sizes. With a /23, the third octet will always be even. It’s not possible to specify a network that goes from to without going to a /22, and that would be and would range form to


ipcalc is a nice tool to have around

apt install ipcalc

# ipcalc

There is a similar one online that I use quite often called “IP Subnet Calculator”.
