Tailscale - Advertise Routes - enabled IP forwarding

Apps and Virtualization
1

I setup the Tailscale-App to use my other apps like immich, paperless, adguard
hosted as a Service privately on TrueNAS (Guide: HOWTO: Host a Service privately on TrueNAS with a valid SSL Certificate)

Now I added advertise routes in the settings of the Tailscale-App.
In the help for this it says:

Help: *Advertise Routes*

Advertise routes
Same as `--advertise-routes` flag.
Needs enabled IP forwarding on the host via System > Advanced Settings > Sysctls.
Please make sure you read and understand the warnings displayed when adding Sysctls

Is there somebody who can help me enabling IP forwarding on the host via System > Advanced Settings > Sysctls. What do I have to fill in under: Add Sysctl for Variable* and Value*?

Did you find a solution to this? I’m also stumped with this.

That’s really helpful, thanks for pointing me in the right direction.

Having now done some more looking into this, is the ipv6 variable

net.ipv6.conf.all.forwarding
