 ProSafe Wireless-N 8-Port Gigabit VPN Firewall FVS318N
Note:  
Some residential broadband ISP accounts do not allow you to run 
any server processes (such as a web or FTP server) from your 
location. Your ISP might periodically check for servers and might 
suspend your account if it discovers any active servers at your 
location. If you are unsure, see the acceptable use policy of your 
ISP.
Order of Precedence for Rules
As you define a new rule, it is added to a table in a Rules screen as the last item in the list, as 
shown in the following figure, which shows the LAN WAN Rules screen for IPv4 as an 
example:
Figure 62. 
For any traffic attempting to pass through the firewall, the packet information is subjected to 
the rules in the order shown in the Outbound Services and Inbound Services tables, 
beginning at the top and proceeding to the bottom. In some cases, the order of precedence 
of two or more rules might be important in determining the disposition of a packet. For 
example, you should place the most strict rules at the top (those with the most specific 
services or addresses). The Up and Down table buttons in the Action column allow you to 
relocate a defined rule to a new position in the table.
