 =====Wireguard=====
-I previously successfully setup [[https://wiki.kptree.net/doku.php?id=linux_router:wireguard|KPTree wireguard]] on my router.  This was installed on "bare metal" as was the nftable based router firewall. I later installed Bind9 DNS and Kea DHCP programs in Docker containers.  I always run Docker in a VM to prevent Docker's packet filtering from affecting the bare metal firewall rules.  I did not move Wireguard to a Docker container as I did not have the need at the time.

I later installed Bind9 DNS and Kea DHCP programs in Docker containers.  I always run Docker in a VM to prevent Docker's packet filtering from affecting the bare metal firewall rules.  Until recently I did not move Wireguard to a Docker container as I did not have the need or time.
+Using Docker [[https://github.com/linuxserver/docker-wireguard|wireguard]] from linuxserver.io is much easier than the manual "bare-metal" setup on my router.  The docker setup is below:
+++++docker-compose.yml|
+<code yaml>---
+services:
+  wireguard:
+    image: lscr.io/linuxserver/wireguard:latest
+    container_name: wireguard
+    cap_add:
+      - NET_ADMIN
+      - SYS_MODULE #optional
+    environment:
+      - PUID=1000
+      - PGID=1000
+      - TZ=Australia/Perth
+      - SERVERURL=kptree.net #optional
+      - SERVERPORT=51820 #optional
+      - PEERS=2 #optional
+      - PEERDNS=auto #optional
+      - INTERNAL_SUBNET=10.13.13.0 #optional
+      - ALLOWEDIPS=0.0.0.0/0 #optional
+      - PERSISTENTKEEPALIVE_PEERS=all #optional
+      - LOG_CONFS=true #optional
+    volumes:
+      - ./config:/config
+      #- /lib/modules:/lib/modules #optional
+    ports:
+      - 51820:51820/udp
+    sysctls:
+      - net.ipv4.conf.all.src_valid_mark=1
+    restart: unless-stopped</code>

+The Wireguard container [[https://github.com/linuxserver/docker-wireguard#server-mode|Server Mode]] documentation give some key points on usage:
+  *Variables ''SERVERURL'', ''SERVERPORT'', ''INTERNAL_SUBNET'', ''PEERDNS'', ''INTERFACE, ALLOWEDIPS'' and ''PERSISTENTKEEPALIVE_PEERS'' are optional variables used for server mode. Any changes to these environment variables will trigger regeneration of server and peer confs. Peer/client confs will be recreated with existing private/public keys. Delete the peer folders for the keys to be recreated along with the confs.
+  *To add more peers/clients later on, you increment the ''PEERS'' environment variable or add more elements to the list and recreate the container.
+  *To display the QR codes of active peers again, you can use the following command and list the peer numbers as arguments: ''docker exec -it wireguard /app/show-peer 1 4 5'' or ''docker exec -it wireguard /app/show-peer myPC myPhone myTablet'' (Keep in mind that the QR codes are also stored as PNGs in the config folder).

 =====Headscale=====
+For my use case Headscale was too complicated to setup.  I am also concerned about the effort to maintain.  So I have decided not to use at this time.
