4.3.4 Port Block

The Port Block function provides a user to set lots of proprietary port numbers. Packets will
be dropped if destination ports (both TCP and UCP) of packets with these assigned port
numbers are on WAN and LAN. The advantage of this feature is to filter some unnecessary
packets or attacking packets on Internet environment or LAN network. Vigor3300 Series
supports ten port numbers to be blocked.

4.3.5 DDNS Setup

The Dynamic DNS function allows the router to update its online WAN IP address, which
assigned by ISP or other DHCP server to the specified Dynamic DNS server. Once the router
is online, you will be able to use the registered domain name to access the router or internal
virtual servers from the Internet. DDNS is more popular on dynamic IP users, who typically
receive dynamic, frequently-changing IP addresses from their service provider.
