TAILMON TAILMON v1.0.20 -July 27, 2024- WireGuard-based Tailscale Installer, Configurator and Monitor (Now available in AMTM!)

[peanstein]

I was hoping I get get a better understanding of the difference having tailscale installed on my RT-AX86S running 3004.388.6_2 and on my Truenas Scale 24.10.2. Is the exit node required for both or is that only needed on one of the 2 installations?

In my router tailscal settings, I advertised my subnet and seems to be running fine, and shows as connected to the tailscal devices page.
In my Truenas system, I advertised my subnet as well as selected it to be an exit node. It also shows as connected in tailscal devices page.

I have tailscale on two laptops, as well as two android phones. Everything connects fine via VPN when outside my intranet (cell network). I can access my Truenas system as well as router login page.

Do I have everything configured correctly or should I configure things differently?

Thanks!

@Viktor Jaep, do you think it would be possible to add a user selectable option that auto-checks for and then auto-updates both Tailmon and separately, the same for Tailscale?

I was inspired by relatively recent developments in MerlinAU along those lines….

I’m hoping someone considerably more experienced like Colin Taylor will drop by, but I’ll give it a go. The answer is, it depends. If you want to keep it super simple, set up one subnet router and exit node on one device, the most powerful one on your tailnet.

A next step would be to add the other device as a subnet router but not to have the subnet active e.g. I have an RPi4 running TS setup so that I can enable it as ‘advertising’ if there’s an issue with my Router’s TS implementation.

The next step would be to have both running TS, each with its respective subnet routers advertising, one being the primary subnet router and the other acting as a failover. There is an order of subnet router use, see TS docs but it’s generally chronological order of setup date.

I’m less experienced on exit nodes and a lot of the capabilities surrounding country-specific exit nodes e.g. are beyond the personal plan. Having two exit nodes is definitely possible on the personal plan (and even a good idea for coffee shop use e.g. ), for those wanting to send specific traffic out a specified exit node.

So as I said in the beginning, it really depends (on what your needs are). It may be that you don’t know what is actually possible and if you do a wee bit of hunting around you end up using capabilities you were not even aware existed . HTH.

I like those suggestions a lot, @jksmurf! I'll add these to my to-do list.
