the device via Internet).
Note: Use “Remote IP Filter” function to prohibit all local stations from accessing
certain web sites on the Internet (requires the web site’s IP address).
TCP/UDP Port Filter: Filter using the port number. You can set filter for a single port or a
range of ports.

Note: You can only set each filter type to either forward or filter. For example, you can’t set
one IP address to forward and set another IP address to filter. You must set them both to
either forward or filter. However, you can set to forward an “Adapter Address” and set to
filter an “IP address”.
