+#
+# Adds TCP/UDP port forwarding rules to the pf firewall (MacOS/BSD).
+#
+# Adds rules for both TCP and UDP in addition to those from /etc/pf.conf.
+# Requires an existing rdr-anchor entry in /etc/pf.conf.
+# Only adds rules temporarily, without changing any files.
+#
+# Usage: ./forward-ports.sh [[nic:]port=[ip:]port [...]]
+#
+# If no network interface is given, forwards from all interfaces.
+# If no IP is given, forwards to 127.0.0.1.
+# If no port forwarding rule is given, resets to the rules from /etc/pf.conf.
+#
+# e.g. forwarding ports 80 and 443 on network interface en0 to ports 8080 and
+# 8443 on localhost respectively:
+# ./forward-ports.sh en0:80=8080 en0:443=8443
