The next step is to specify if you want the policy rule to apply to
Inbound
or
Outbound
packets. Inbound here means from the WAN to your LAN, while
Outbound means from your LAN to the WAN. The
Direction
drop-down
menu allows you to choose which direction the DFL-600 will filter packets
that meet the criteria of the policy rule.
Please Note:
at the time of the writing of this manual, the
Inbound
direction
specification for
Policy Rules
only applies to the
Application (ALGs)
and
Virtual Servers
that have been set up on the
NAT
page.
If, for example, you want to prevent the TELNET protocol from being used
to access PCs on your LAN from the Internet (WAN), your would specify
Inbound
. If you want to prevent PCs on your LAN from using TELNET to
access PCs on the Internet (WAN), you would specify
Outbound
. Entering
two policy rules for inbound and outbound packets will totally eliminate a
given protocol from being used to across the DFL-600.
You can specify a range of TCP or UDP ports using the
Port Range
field.
Selecting
Any
will prevent any port from being used.
In addition, you can specify a range of IP addresses
−
as either a source or a
destination
−
that the policy rule will be applied to.
Once you have configured the policy rule and clicked on the
Apply
button,
the rule will be entered into the
Service Rules
table. If you need to change
the policy rule, click on the icon in the
View
field of the
Service Rules
table.
This will allow you to view and modify the rule’s configuration. To delete a
policy rule, click on the icon in the
Del
field.
Global Policy Status
Once you have configured the Policy Rules, you need to determine how the
DFL-600 will apply these rules to the packets that cross between your LAN
and the Internet (WAN). The Global Policy Status page enables you to
specify this.
“Default” on this page means “if no packets that meet the criteria established
in the policy rules, then ...” either “allow all” or “deny all”. On the Global
