Tailscale VPN

Setup tailscale to access network externally

Proxmox access

1. Install tailscale client on access devices
2. Install tailscale on target device

curl -fsSL https://tailscale.com/install.sh | sh

3. Access target device by enabling tailscale VPN and access via assigned IPv4 or IPv6

LXC access

Instructions taken from https://dustri.org/b/running-tailscale-inside-of-a-proxmox-container.html

1. Add some lxc config in proxmox specifying correct ID - 100 in this example

echo 'lxc.cgroup.devices.allow: c 10:200 rwm' >> /etc/pve/lxc/100.conf
echo 'lxc.mount.entry: /dev/net/tun dev/net/tun none bind,create=file' >> /etc/pve/lxc/100.conf

2. Enter lxc container

pct enter 100

3. Install and configure tailscale

curl -fsSL https://tailscale.com/install.sh | sh
echo 'net.ipv4.ip_forward = 1' | tee -a /etc/sysctl.conf
echo 'net.ipv6.conf.all.forwarding = 1' | tee -a /etc/sysctl.conf
sysctl -p /etc/sysctl.conf
reboot
