Tailscale: no Internet out of the Box... solved

Hey,

Slate6 as client of Flint2
as soon i activate the Endpoint provided from the Flint to Slate
i loose the internet-connection.

On the Slate its 4.8.4 and on Flint 4.9.0

i deactivatet all wireguardVPN related switches and adguard
and have no rules changed in luci or via ssh.

The Subnets are proposed as suggested and the tailscale-ip is working
for the slate-GUI while i cannot reach the Flint or Internet when Endpoint is selected/active on the Slate

any hint is appreciated // thx
