In Zerotie network is an option that says "Allow Ethernet Bridging".

If that is turn on, can I access my ip camera on my remote Windows computer like this:

local IP:port, via VPN IP

Or do I need to setup other things as well?

Hello guys. Can I play Don't starve together pocket edition with my friends using Zerotier as a LAN? If yes, how to do it? ty

Is it possible to configure multiple relays in the local.conf for tcpFallbackRelay?

Hi -

well, QuTS 6.0.1 won't run the existing ZeroTier downloads. You have to run a docker container.

https://github.com/zerotier/ZeroTierOne/blob/dev/ext/installfiles/linux/zerotier-containerized/Dockerfile

boy - I sure wish there was a little details article or YouTube video on how to exactly do this !

I guess it wasn't profitable enough for ZeroTier to keep doing this for QNAP and Synology NAS systems.

I have a zerotier network that has been stable for some months. Yesterday, I started getting errors because nodes couldn't talk to each other.

Nothing looks wrong on the control panel: all nodes have allocated IP addresses and are checking in regularly. Similarly, the nodes I can reach by other means show nothing wrong when I do `zerotier-cli info`. There is nothing custom in the flow rules.

However, when I do `ip a` or `zerotier-cli -j listnetworks` on any of the nodes, none of them have an allocated IPV4 address on the zerotier interface.

I've tried leaving and rejoining. This seems to work OK, except that no IPv4 address is on the nodes interface. The control panel thinks it has.

Any ideas?

Hi, I'm new to ZeroTier and haven't been able to find an answer to my issue. I have just bought a Cudy P5 router that can run ZT. I want it at my cottage (5G cellular coverage only, no cable or fibre internet) so I can access local devices connected to it via either WiFi or LAN.

Some of them are Raspberry Pi's with ZT clients installed (weather station, etc), so should be accessible. Others are 2x Webcams, Airconditioner, etc. without ZT clients. I thought I would be able to reach them as well, but the guidelines I have seen indicate to me that I need to upgrade my plan to Essential Level for $18/month :(. Is that correct, or is there another way to set up my network using a Basic plan?

I run ZeroTier in a Docker container on a Synology DS124 with DSM 7.3. After DSM updates or reboots, the ZeroTier layer repeatedly failed to return even though the container had a restart policy.

Symptoms

The container remained stopped:

Status: Exited (143)
Restart policy: unless-stopped

Docker retained this error:

error gathering device information while adding custom device
"/dev/net/tun": no such file or directory

The ZeroTier interfaces were missing, and the NAS was no longer reachable through the overlay network.

Root cause

This turned out to be a boot-order problem:

1. DSM stops Container Manager cleanly during an update or shutdown.
2. /dev/net/tun is created dynamically during boot.
3. Container Manager may try to restore the ZeroTier container before the TUN device is ready.
4. The container fails or remains stopped.
5. unless-stopped does not reliably recover a container that DSM explicitly stopped.

The ZeroTier data itself was not lost because it was stored persistently outside the container.

Final fix

I used three layers:

1. Change the restart policy:

​

docker update --restart always zerotier-one

1. Add a DSM boot-triggered task that:
   • waits for /dev/net/tun;
   • creates it if DSM does not;
   • waits for Docker;
   • starts the container;
   • confirms ZeroTier reaches ONLINE;
   • abandons recovery after 90 seconds so it cannot block DSM boot.
2. Add a periodic watchdog task that performs the same checks and exits silently when everything is healthy.

The boot task is configured in:

Control Panel
→ Task Scheduler
→ Create
→ Triggered Task
→ User-defined script
→ Event: Boot-up
→ User: root

The watchdog is a normal scheduled task running every five minutes.

Minimal recovery script

This is the shortened version. The fuller version adds locking, DSM Log Center integration and hard global deadlines.

#!/bin/sh

CONTAINER="zerotier-one"

# Give DSM time to create TUN.
WAITED=0
while [ ! -c /dev/net/tun ] && [ "$WAITED" -lt 30 ]; do
    sleep 5
    WAITED=$((WAITED + 5))
done

# Repair TUN if DSM did not create it.
if [ ! -c /dev/net/tun ]; then
    modprobe tun 2>/dev/null || true
    mkdir -p /dev/net
    chmod 755 /dev/net
    rm -f /dev/net/tun
    mknod /dev/net/tun c 10 200 || exit 1
fi

chown root:root /dev/net/tun
chmod 666 /dev/net/tun

# Wait for Docker.
WAITED=0
while ! docker info >/dev/null 2>&1 && [ "$WAITED" -lt 60 ]; do
    sleep 5
    WAITED=$((WAITED + 5))
done

docker info >/dev/null 2>&1 || exit 1

# Start the container if required.
if ! docker ps --format '{{.Names}}' | grep -qx "$CONTAINER"; then
    docker start "$CONTAINER" || exit 1
fi

# Confirm ZeroTier responds.
WAITED=0
while ! docker exec "$CONTAINER" zerotier-cli info >/dev/null 2>&1 \
      && [ "$WAITED" -lt 30 ]; do
    sleep 5
    WAITED=$((WAITED + 5))
done

docker exec "$CONTAINER" zerotier-cli info
docker exec "$CONTAINER" zerotier-cli listnetworks

Validation

After reboot, the boot task logged that /dev/net/tun was initially absent, waited, started the container and completed recovery after approximately 39 seconds.

And all work back.

Hello Reddit, I am trying to host a server for Hollow Knight multiplayer with a friend, following a Steam guide. It tells me to open the control panel to give my friend the managed IP. But I can't find it on the website, nothing happens when I try to open the application on my laptop and the taskbar trey doesn't give me the option to open it either. Where can I find this thing?

Link to the guide I'm following:
https://steamcommunity.com/sharedfiles/filedetails/?id=2601449230

I have been using ZeroTier since 2022, and the last time I use it was 2025

I want to use it again recently but for some reason it doesn't work anymore

It says No Network Access but I don't know if it's always been like that or not

How do I solve this?

I amt want to access some devices at my cottage. I have a TP-Link 5G router there that doesn't work with ZT. Behind it I have a number of devices, including some Raspberry Pi's. I have added ZT to them and can access them fine. But I also want to use (at least one of) them to access other devices that won't accept ZT (WiFi-capable air conditioner/heater, Webcams, etc). But it looks to me like I need to configure ZeroTier Central to Add Routes - and that this requires a paid plan. Is that correct? Or is there an alternative?

I found code in Zerotier that sends traffic at different QoS priorities(screenshot below). :

Can I set this QoS anywhere in config(Zerotier Central, local.conf, or args), or is editing the source code the only way?

--------------------

Details (optional, skip if you want) :

I'm sending gimbal camera control(port 2000) and video over the same Zerotier link at the same time, and I want the gimbal control traffic to have higher priority than the video.

I just started with Zerotier and signed up with trial to see if it could increase speed compared to SonicWall Global VPN. I can connect fine between client and a hosted Windows PC behind a SonicWall. Can ping Zerotier IP on host. I setup the Route in Zerotier to route to LAN IPs on host side but can't ping or access any devices. Can anyone help me on what I am missing? Are there rules needed in the SonicWall to allow this?

Thanks!

I am having a hard time with joining a ZT network from IOS devices. In the app, you turn the toggle. It remains like that for a moment and the toggle then flashes off. You don't see a device in de ZT central dashboard. The device seems to just not join. Is this a known bug? IOS 26.5.2

I'm new to zerotier and trying to figure this out. I have a phone and vpn router both connected and recognized by zerotier central (free account). I can access the router remotely but not home assistant which is connected through the router by LAN. I have tried letting in the phone's ZT IP address through the firewall but no success. I also enabled the bridging option to allow lan access in zerotier central. What am I missing?

I know there is a direct ZT integration with home assistant but I currently have HA blocked from internet accessband I'd like to keep it that way.

Hi everyone, I just started to use Zerotier. I want to ask something. When I buy Essential plan which is give 5 networks and 10 device Included. Is that mean I can totally use 50 different device in all networks?

Does anyone know what could be the issue? We have Windows Intune/Entra-ID enrolled workstations with the latest ZeroTier. Every hour when the token expires for SSO, we have to manually click on "Open SSO Login". It seems that the token is not automatically renewed.

The app registration has been checked and includes all the API that is needed. Additionally in hindsight i find it even weird that we have to manually sign in with SSO at all since the device is already working under the SSO user.

Any clue what could be the cause? The logging in Entra ID only shows that its a interactive sign-in.

Although the official documentation (https://docs.zerotier.com/roots/) mentions that on iOS you can add a private planet via https://joinzt.com/addplanet?v=1&planet=$base64_planet_file, the current version 1.16.0 does not have this feature. Has the settings feature also been removed? I’m an early user and many of my devices rely on Private Root Servers. Is there any workaround?

So I had some networks for BOZ on Mobile. Today I got an email telling me to log back in ory account was gonna get deleted. I did as I was told. But my networks were missing. I freaked out. Added it back in the mobile app on a new device and it recognised the network. But for me it isn't showing up. Neither in Legacy or the New Version of Zero Tier. I am pretty worried.

Ps. My networks were pretty basic. No coding. Made it in the browser years ago. Just helps people join. Also I don't have a pc anymore.

Dear Redditers,

I enabled the ETHERNET BRIDGING option in the ZeroTier for this computer (win 7 client, authorized, home computer, Local LAN connected)

thinking i can login to my CCTV/DVR from outside home thru my android cellphone which is no successful at the moment. can anyone shade some lights as to what i'm missing ?

I directly used the local IP Address entry or from web browser, also unsuccessful.

Note: The DVR/CCTV works/connect just fine when in home network.

And the ISP is using NAT on us home user (Obviously, thats why ZeroTier comes into play)

Anyone having problems with ZT? ZT Central shows that none of my nodes has been seen in the last hour but some of them are working, some aren't.

Hi -

I am hoping that this is something stupid that I am doing. I am trying to simply log into my ZeroTier account - by going to www.zerotier.com, and clicking on Login on the upper right hand corner, like I have done for years. When I click on Login - nothing happens - no window opens. I tried multiple web browsers (Chrome, Firefox, Edge) - and so I thought "ok - something weird happened to my PC - let me try another computer" - I am on my M4 Mac mini right now, and using Safari (and Chrome and Firefox) - and SAME ISSUE - I click on the Login screen, and I cannot log in. I just called my client, to ask if he could try it on his computer - and he too - cannot log in !!!!

Is this a new issue, or did ZeroTier change something. I must be doing something very stupid.

The official container https://hub.docker.com/r/zerotier/zerotier is still on 1.14.2 and has not been update for over 1 year!

I'm using ZeroTier to play LAN games with a friend in the same city. We're both connected to the same ZeroTier network, but when we play Left 4 Dead, we're getting around 150-300ms ping. It's playable but not great for a game that should be snappy locally.

​

Here are the details:

​

· Network setup: Both on the same ZeroTier network (I created it through ZeroTier Central)

· Game: Left 4 Dead (LAN mode)

· Location: Both in the same city (we're literally a few kilometers apart)

· Ping: 150-300ms consistently

​

My questions:

​

1. Is it normal for ZeroTier to add this much latency even when both devices are in the same region?

2. Can I control which region or server my ZeroTier network uses? I didn't see any option for this when creating the network.

3. What can I do to lower the ping? Would a private Moon server help?

4. Could this be because of my VPN? (I don't use one, but I know ZeroTier is essentially a VPN itself)

​

Note: I'm using Linux and my friend uses windows, firewall is off on the hosting device (me)

​

Even if my friend hosts the game, i me myself getting 200ms evn if i have good internet connection
