Tailscale has messed up my internet connection (lemmy.ml)

I have no idea why this is happening on my arch linux machine. I was trying to set it up as a client device, and now i have no internet connection on my wired network. This is bare metal not docker. I just wanted to add the device to my tailnet.

Any help is appreciated

Thank you for your time.

EDIT: I have completely uninstalled tailscale yet I still do not have internet access. I am connected to the network fine. If i cinnect through wifi it is the same result.

EDIT 2: the error I am recieving is limited connectivity.

EDIT 3: It has been fixed! scrion@lemmy.world solution fixed it!

Did you undo the reverse path strict filtering your guide suggested?


net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.all.rp_filter = 1

Above is what the guide suggests to force reverse path strict filtering. Try setting as shown below:


net.ipv4.conf.default.rp_filter = 0
net.ipv4.conf.all.rp_filter = 0

According to the guide, “By default, these are set in /usr/lib/sysctl.d/50-default.conf”

No I did not edit this at all. Bkth were set to the value '2'

I changed them both to 0 and 1 and it did not fix my issue 🫤

Hold up. Dont change stuff in /usr/lib/. That directory contains default settings that comes with packages. If you need to overwrite those settings use /etc for that.
