DESCRIPTION
Enter a descriptive name of up to 31 printable ASCII characters (except Extended
ASCII characters) for the firewall rule. Spaces are allowed.
Select this to turn this rule on. Clear this to turn this rule off.
Do you want your rule to apply to packets with a particular (single) IP, a range of IP
addresses (for example 192.168.1.10 to 192.169.1.50), a subnet or any IP
address? Select an option from the drop-down list box that includes: Single
Address, Range Address, Subnet Address and Any Address.
Enter the single IP address or the starting IP address in a range here.
Enter the ending IP address in a range here.
Enter the subnet mask here, if applicable.
Click Add to add a new address to the Source or Destination Address(es) box.
You can add multiple addresses, ranges of addresses, and/or subnets.
To edit an existing source or destination address, select it from the box and click
Modify.
Highlight an existing source or destination address from the Source or
Destination Address(es) box above and click Delete to remove it.
Highlight a service from the Available Services box on the left, then click the
select icon to add it to the Selected Service(s) box on the right. To remove a
service, highlight it in the Selected Service(s) box on the right, then click the
deselect icon.
Next to the name of a service, two fields appear in brackets. The first field indicates
the IP protocol type (TCP, UDP, or ICMP). The second field indicates the IP port
number that defines the service. (Note that there may be more than one IP
protocol type). For example, look at the DNS entry, (UDP/TCP:53) means UDP
port 53 and TCP port 53. Click the Custom Service link to go to the Service
screen where you can configure custom service ports. See the device User's
Guide for a list of commonly used services and port numbers.
You can use the [CTRL] key and select multiple services at one time.
Select everyday or the day(s) of the week to apply the rule.
Select All Day or enter the start and end times in the hour-minute format to apply
the rule.
This field determines if a log for packets that match the rule is created (Yes) or not
(No). Go to Device Operation > Device Configuration > Device Log > Log and
select the Access Control log category to have the device record these logs.
Select the check box to have the device generate an alert when the rule is
matched.
