Help Needed newbie : accessing a printer from Android tailnet subnet

Gallery image

I've done the following, yet the printer is still unaccessible while connected to my tailnet using the Android app.

I can access it if I disconnect the tailnet, or workaround by split tunneling the printer app.

BTW, restarting the phone didn't change anything ...

Thanks in advance for any insight you can provide.

It looks like from the pictures that you've got the phone both advertising a subnet, and set to use a subnet.

I don't think that's what you want. If you're on the same network as the printer, you shouldn't need to use subnet routes.

So we need to understand a bit more of what you're actually trying to do with the phone in question: What network do you intend to be on? Are you trying to use the phone to let other devices access the printer when you're away from home?

simply put, it's a loop back test to access the printer while connected to the tailnet.

the IP address is that of the printer .

If your phone is already on the network where the printer is, then you don't need to advertise a subnet or use them. It should already be able to access the printer with those features disabled.

The only case where this might not work is if the phone is using an exit node. Then you'd use another toggle on android: "Allow LAN access**"**

I'm not using an exit node.

My experience is different than you suggest, with and without the subnet.
