Tailscale networking not working.

Hello, I can't seem to get networking to work at all. Despite having an exit-node setup.

I've tried a ton of different things

do you have ip forwarding enabled in your exit node? cat /proc/sys/net/ipv4/ip_forward
HX MutantRabbit767
HX MutantRabbit767OP•5w ago
it says 1 I didn't see ip forwarding documented on the exit node tailwind documentation
Yuri
Yuri•5w ago
1 means that it is enabled, so the issue is something else
Yuri
Yuri•5w ago
can you show the content of the "Edit route settings" screen?

that also looks fine... are you able to use the device as an exit node from another client? like your phone for example or another pc
HX MutantRabbit767
HX MutantRabbit767OP•5w ago
let me try with my phone
Yuri
Yuri•5w ago
a good test is to disable wifi on the phone, route all traffic through tailscale, and check that the external ip is seen as the same as your exit node, for example using https://www.whatismyip.com/
WhatIsMyIP.com®
What Is My IP?
Check the IP address assigned to your device. Show my IP city, state, and country. What Is An IP Address? IPv4, IPv6, public IP explained.

strangely enough it works with my android phone
Yuri
Yuri•5w ago
then it might be an actual issue with WebVM... would you mind trying again by refreshing the tab and logging in again?

HX MutantRabbit767OP•5w ago
well sort of

ive done that a bunch of times and with diff browsers
Yuri
Yuri•5w ago
wait, do you mean that you tried to use the phone as an exit node?
HX MutantRabbit767
HX MutantRabbit767OP•5w ago
using the phone as an exit node worked for the curl script example
Yuri
Yuri•5w ago
I see. I was suggesting to use the phone as the user of the previous exit node, to make sure it was working correctly, without WebVM in the picture
HX MutantRabbit767
HX MutantRabbit767OP•5w ago
oh sorry, i understand
Yuri
Yuri•5w ago
about the could not resolve issue, try the command a few times. I noticed that DNS is very sensitive to losing a few packets and that happens sometimes

my tailwind setup must be cursed as hell
Yuri
Yuri•5w ago
yeah so there is some issue with the exit node itself, but I am not sure how to help with that beyond what I initially suggested.

this?
HX MutantRabbit767
HX MutantRabbit767OP•5w ago

this is really cool tbh
Yuri
Yuri•5w ago
I suggest trying to debug the issue without WebVM in the picture, so that you can ask help from Tailscale too. I think that we established that the WebVM side works, and that there is something wrong with the exit node setup on your pc

HX MutantRabbit767OP•5w ago
okay dude WTF

this is actually so sick ill figure out the exit node situation later for now im gonna mess with this this is cool man
Yuri
Yuri•5w ago
appreciated 🙂

HX MutantRabbit767OP•5w ago
see like i can see the use case for this being like oh i need to quickly compile and test a script for linux and your main OS is windows instead of using WSL you can just type webvm.io connect tailscale in 2 seconds then clone into whatever right
Yuri
Yuri•5w ago
yeah that is a use case we have in mind. A similar situation is if you have a locked chromebook (like many schools give to students)
HX MutantRabbit767
HX MutantRabbit767OP•5w ago
thats even smarter actually

okay i just got it working through my laptop
echo 'net.ipv4.ip_forward = 1' | sudo tee -a /etc/sysctl.d/99-tailscale.conf
echo 'net.ipv6.conf.all.forwarding = 1' | sudo tee -a /etc/sysctl.d/99-tailscale.conf
sudo sysctl -p /etc/sysctl.d/99-tailscale.conf
echo 'net.ipv4.ip_forward = 1' | sudo tee -a /etc/sysctl.d/99-tailscale.conf
echo 'net.ipv6.conf.all.forwarding = 1' | sudo tee -a /etc/sysctl.d/99-tailscale.conf
sudo sysctl -p /etc/sysctl.d/99-tailscale.conf

the reason ip_forward was enabled was because of my previous wireguard configuration im pretty sure
Yuri
Yuri•5w ago
ah so the ipv6 forwarding was missing?
HX MutantRabbit767
HX MutantRabbit767OP•5w ago
ipv6 didnt really change anything, difference was the existance of a 99-tailscale.conf file im pretty sure let me actually try removing ipv6 forwarding to try testing
Yuri
Yuri•5w ago
thanks, might be useful for helping future troubleshooting

HX MutantRabbit767OP•5w ago
okay yeah, ipv6 forwarding was not the issue thanks for setting me down the right troubleshooting path 🔥
