Tailscale PVT VPN will not work on the plusnet network

[#1]

@timsansom 

Its as though your router (or linux device) doesnt think that the tailscale IP (192.200.0.109) is outside its LAN subnet and therefore isnt routing via the default gateway.

What is the LAN subnet mask showing on both the router and linux box ? it would normally be /24

[#2]

it would normally be /24

or 255.255.255.0 

if you've got a mask somewhere showing 255.0.0.0 then that will prevent routing to the tailscale IP

[#3]

It could be that it shouldn't be > /24.

However. It could be > /24. (192.168.0.0 -> 192.168.255.255)

It can also be < /24.

[#4]

yes its a class C address /24

[#5]

With traceroute providing strange result.

are you using a virtual machine for this, if so NAT or bridged network interface?

have you setup any routes or just using the devices default gateway?

what does netstat -r (routering table) show?

If you have a Hub two, do you see the same issue?
