wireguard_port_mappings: []

wireguard_peers:
  - name: peer1
    allowed_ips:
  - name: peer2
    allowed_ips:

wireguard_log_confs: True

Route inbound traffic to wireguard

Customize iptables rules

Works only with https://github.com/dddpaul/docker-wireguard until (and if) linuxserver/docker-wireguard#202 will be merged.

For example, these rules will route inbound traffic to "internal" web servers:

wireguard_post_up: >-
  iptables -t nat -A PREROUTING -p tcp --dport 8080 -j DNAT --to-destination 10.13.13.2:8080;
  iptables -t nat -A PREROUTING -p tcp --dport 8443 -j DNAT --to-destination 10.13.13.3:8443;
  iptables -t nat -A POSTROUTING -p tcp -d 10.13.13.0/24 -j MASQUERADE;
  iptables -A FORWARD -i %%i -j ACCEPT; iptables -A FORWARD -o %%i -j ACCEPT; iptables -t nat -A POSTROUTING -o eth+ -j MASQUERADE
wireguard_post_down: >-
  iptables -t nat -D PREROUTING -p tcp --dport 8080 -j DNAT --to-destination 10.13.13.2:8080;
  iptables -t nat -D PREROUTING -p tcp --dport 8443 -j DNAT --to-destination 10.13.13.3:8443;
  iptables -t nat -D POSTROUTING -p tcp -d 10.13.13.0/24 -j MASQUERADE;
  iptables -D FORWARD -i %%i -j ACCEPT; iptables -D FORWARD -o %%i -j ACCEPT; iptables -t nat -D POSTROUTING -o eth+ -j MASQUERADE
