Usage:
./scripts/add-port-forward.sh --external-port PORT --target IP --target-port PORT [options]
Options:
--external-port PORT Port expose sur l'adresse WAN pfSense.
--target IP IP de la machine interne.
--target-port PORT Port de destination sur la machine interne.
--protocol PROTO tcp, udp ou tcp/udp. Defaut: tcp
--interface IFACE Interface pfSense. Defaut: wan
--description TEXT Description de la regle.
--associated-rule MODE new, pass ou none. Defaut: new
--no-apply Cree la regle sans appliquer les changements.
-h, --help Affiche cette aide.
Exemple:
./scripts/add-port-forward.sh --external-port 8443 --target 192.168.1.50 --target-port 443 --protocol tcp
Sans argument, le script demande les valeurs manquantes en interactif.
