Turris

opkg install kmod-veth
opkg install kmod-ipt-extra
opkg install iptables-mod-extra

• Install a new container (I created an arch linux container)
• Open up the /srv/lxc/containername/config file for editing:

# Be aware this has security implications
lxc.include = /usr/share/lxc/config/nesting.conf

# Configure network to bridge to lan
lxc.net.0.type = veth
lxc.net.0.link = br-lan
lxc.net.0.flags = up
lxc.net.0.name = eth0
lxc.net.0.hwaddr = 22:11:85:de:f9:fb
# Add the following lines to open up access to the host, allowing docker to successfully start
raw.lxc: |-
lxc.mount.auto = cgroup:rw:force
lxc.cgroup.devices.allow = a
security.nesting: "true"
security.privileged: "true"
lxc.cap.drop =

• Save and exit the config file
• Start the lxc container

lxc-start -n <container_name>

• Attach to the console of the lxc container

lxc-attach -n <container_name>

apt install iptables kmod
update-alternatives --set iptables /usr/sbin/iptables-legacy
