 ==== dyndns-host-open ====
-This implements support to open ports for DynDNS IPv4 hosts.
+This plugin provides EXT->Local firewall 'host-open' rules using hostnames (via periodic DNS lookups) rather than static IPv4 addresses.
+Should the hostname resolve to multiple IPv4 addresses, a rule for each address will be opened.
-If you allow common services, in particular SIP or SSH, from public dynamic IPv4 addresses, it is highly recommended to enable this plugin and don't allow these services from the public by default.
