FriendlyNET VPN Security Router 34
Your selections should look like this:
• LAN Side Filter Enabled: Enabled
• Default LAN Side Filter: Pass
• Filter Entry: Block
• Protocol: TCP
• IP Address Range: 192.168.123.10 to 192.168.123.20
• Destination Port Range: 119-119
Click Save to add the filter rule (to delete a filter rule, check the “del”
box and click the del button).
This filter will prevent any LAN user whose IP address is in the indi-
cated range from using NNTP.
3.5.2 WAN Filter Settings
Next, access the WAN Filter Settings page by selecting the button
from the left-side menu. A WAN Filter works similarly to the LAN
Filter. If, for example, you need to run a web server from behind
your firewall at your home office, but you only want people in your
main office to be able to connect to it, you would want to make the
default policy of your WAN Filter Block.
Your setting would look something like this:
• WAN Side Filter Enabled: Enabled
• Default WAN Side Filter: Block
• Filter Entry: Pass
• Protocol: TCP
• IP Address Range: 172.16.203.1 to 172.16.203.254
• Destination Port Range: 80-80 (HTTP)
Click Save to add the filter rule. These settings will allow people in
your office (where the IP addresses are in the range indicated) to
connect to your web server (since web servers use TCP port 80),
but will not allow anyone else to connect.
