Connect to an esp32 from afar

[PapaLanc]

I have a GL-MT300N-V2(Mango) Firmware 4.3.18

I am using zerotier for other systems. So I was trying to stick with it. But open to other ideas. Using T-Mobile home internet so there is no port forwarding available.

I have installed the (outdated) zerotier package from the GUI, but it does not show under applications?

I have also tried a couple different links on how to configure with Putty, but neither have been able to complete the suggested step.
Link 1
Link 2

Any ideas on how to get zerotier up and running?

Thanks,
Papa Lanc

I have also tried a couple different links on how to configure with Putty, but neither have been able to complete the suggested step.

https://openwrt.org/docs/guide-user/services/vpn/zerotier#basic_configuration

The "basic configuration" is mostly all you need. What happens if you do this?

[PapaLanc]

This line returned an error
uci add_list zerotier.my_zt_net.join=<My_network_Id>

-ash: syntax error: "unexpected newline"

I did go through this

AR750S ZeroTier Setup Guide?

Create an account in ZeroTier Central https://my.zerotier.com, then create a Network on it Install ZeroTier on AR750S Edit set enabled option to 1, and set join to your network ID in the configuration file /etc/config/zerotier Start ZeroTier in AR750S via /etc/init.d/zerotier restart Stop and remove MWAN3 package, which will change the route decision. The command you need to execute in AR70S ssh console: mwan3 stop && opkg remove mwan3 --force-depends Configure the firewall, add those lines …

without the remove wan part and my router shows up in zerotier and I can get to it using the zerotier ip

but my esp32 that is connected to the wifi of the yellow box does not show up

I wonder if clients, it shows offline but it is actually working. It show on boot (esp32 boot) but the program running on it really does not generate much traffic

Thanks for looking

The link you sent for openwrt has an error
It needs a tick ' after 'vpn

uci set firewall.@forwarding[-1].dest='vpn
 
# Commit changes
uci commit
 
# Reboot
reboot

So, again, my yellow router shows up at zerotier and I can access it from the zt IP.
Is my esp device connected to the wifi of the box supposed to show up at ZT?

@PapaLanc

Is my esp device connected to the wifi of the box supposed to show up at ZT?

No, it won't show up there. You need to use routing rules to make it reachable via ZT.

Like this? But nothing shows up
xx is my ZT addy
192.168.8.202 is my esp32

I really have no clue what I am doing

[PapaLanc]

I got it working with this
But it is very flaky. I think the little router does not have enough umph to work well
