ipv4.ip_forward not persisting

[Doosty]

I need to set this sysctl value but something is overriding it at reboot. Ive tried several different ways to set this value on bootup but nothing sticks. I would need to manually ssh into my pi and run sudo sysctl -p /etc/sysctl.d/99-tailscale.conf everytime my pi is restarted. Please advise me how to make these sysctl values persistant. Thank you.

net.ipv4.ip_forward = 1
net.ipv6.conf.all.forwarding = 1

@Doosty The AutoHotspot feature is disabling it. When no defined SSIDs are found and the ConsolePi goes into hotspot mode it enables ip forwarding. When it connects to a defined SSID it ensures the hotspot is disabled and disables ip forwarding.

You can disable autohotspot

• change ConsolePi.yaml and disable the hotspot hotspot: false (just prevents it from being configured when you use consolepi-upgrade
• sudo sysctl disable autohotspot

I also just pushed an improvement in v2023-6.5. You can upgrade using consolepi-upgrade. I added logic to the autohotspot script that will look for net.ip.ip_forward = 1 in the sysctl files. It will only disable ip_forwarding if there is not configuration defined that enables it. So it should persist now with or without autohotspot enabled.

Thank you for the reply and update, however

• i did consolepi-upgrade, rebooted, verified 2023-6.5 with consolepi-version, but it did not help with persisting the ipforwarding

I have

• net.ipv4.ip_forward=1 set up in /etc/sysctl.conf & /etc/sysctl.d/99-tailscale.conf
• sudo sysctl -p /etc/sysctl.d/99-tailscale.conf set up in /etc/rc.local & /etc/init.d/tailscale

Setting hotspot: false in /etc/ConsolePi/ConsolePi.yaml seems to work though. I dont need hotspot for now so it is ok. Thank you for the help.

Thanks for the update. I'll re-test. Get it it to work with hotspot enabled.

OK now (🔖 v2023-6.6) it should work with or without autohotspot.
