IMHO the simplest solution is to provide a "bridge" connection to your eth device (wifi won't work) on your host. This way your containers will get an IP from your LAN router and be available from every other device on your internal LAN. If you then port forward to one of the container IPs from your router then it's live on the 'net. If using *buntu then make sure the bridge-utils package is installed and if using a normal host desktop with NetworkManager then try these two config files (change enp4s0f1 to your eth device, and address1)... ~ cat /etc/NetworkManager/system-connections/lxdbr0 [connection] id=lxdbr0 uuid=2140d6a8-fb95-4d93-9488-58b64e216b81 type=bridge interface-name=lxdbr0 permissions= [bridge] stp=false [ipv4] address1=192.168.X.XX/24,192.168.X.1 dns=1.1.1.1; dns-search=local.lan; method=manual [ipv6] addr-gen-mode=stable-privacy dns-search= method=ignore ~ cat /etc/NetworkManager/system-connections/enp4s0f1 [connection] id=bridge-slave-enp4s0f1 uuid=f9691217-52c2-499e-b310-d5ccd7e1373f type=ethernet interface-name=enp4s0f1 master=lxdbr0 permissions= slave-type=bridge [ethernet] auto-negotiate=true mac-address=80:FA:5B:00:2C:48 mac-address-blacklist= [ipv4] dns-search= method=link-local [ipv6] addr-gen-mode=stable-privacy dns-search= method=auto OR... if using systemd-networkd then try these... ~ cat /etc/systemd/network/MyBridge.netdev [NetDev] Name=lxdbr0 Kind=bridge ~ cat /etc/systemd/network/MyBridge.network [Match] Name=lxdbr0 [Network] #DHCP=ipv4 Address=192.168.X.XX/24 Gateway=192.168.X.XX DNS=1.1.1.1 ~ cat /etc/systemd/network/MyEth.network [Match] Name=e* [Network] Bridge=lxdbr0
