Tailscale subnet error

[Aidancov1]

I have an Asus router and a RPi with TailScale and AdguardHome. I have DNS set to my Adguard instance to block ads. I installed Tailscale on RPi and setup as shown in tutorials all works apart from when I try to add my router as a subnet using sudo tailscale up --advertise-routes=192.168.0.0/24 it comes back with the below message-

Warning: UDP GRO forwarding is suboptimally configured on eth0, UDP forwarding throughput capability will increase with a configuration change.
See https://tailscale.com/s/ethtool-config-udp-gro
Error: changing settings via 'tailscale up' requires mentioning all
non-default flags. To proceed, either re-run your command with --reset or
use the command below to explicitly mention the current value of
all non-default settings:

tailscale up --advertise-routes=192.168.0.0/24 --advertise-exit-node

Hope someone can help thanks

192.0.0.0/24 is not a valid LAN subnet - or at least you shouldn't be using it as such. Did you really mean 192.168.1.0/24 or 192.168.50.0/24?

 

[Aidancov1]

My router is 192.168.0.1 so what should I use for the subnet?

Yes sorry Ive corrected that but when I run this script 'tailscale up --advertise-exit-node --advertise-routes=192.168.0.0/24'

I still get the below error

Warning: UDP GRO forwarding is suboptimally configured on eth0, UDP forwarding throughput capability will increase with a configuration change.

I presume you're doing this on your RPi ?

The GRO message is just a warning so you can ignore that. As for the error message, just enter the command it told you to.

 

[Aidancov1]

Okay thanks. Just not sure why I still have a box saying waiting for approval when it says subnet already approved.

 

[ColinTaylor]

It's showing you that 192.168.0.0/24 is approved and there's nothing awaiting approval.

Ah okay thanks so I've done it right. Great.
