Hello there.
I have had a Brume 2 lying around quite some time that served no purpose.
(Gosh, may openWRT grant us an out-of-the-box IPoE compatibility)
It's a small but mighty box. so i thought i could repurpose it to be something like a linux home server.
thankfully, i was able to install openwrt on it. my homelab heavily depends on tailscale for connectivity. so i went ahead, did some research and pulled off.
it doesn't give me error or anything. But subnet routing & exit node doesn't work at all.
i used these guides primarily:
- openwrt documentation for tailscale
- i followed 'Initial Setup' as well as 'How to setup a Subnet Router/Exit Node'
- Subnet routers · Tailscale Docs
- i made sure to do these to get the subnet routing to work
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
It just doesn't work. No error on both the brume 2 and Tailscale web interface or anything. Could you guys help me with at least troubleshoot what's going on?
