Manually adding or specifying a filter rule for a range of ports
Procedure
-
If needed, under the Filter Rules enter the IP address
of the VIP in the
Host
field. -
For the type of filter rule, select
Port Range
, which sends the specified traffic to the selected instance. -
Use the same IP address for each port range filter rule.
- If multiple IP addresses are needed and are grouped into a subnet,
then a subnet mask can be applied to the base IP address. For example,
an entry of
66.211.169.0/24
matches the first 24 bits of the IP address (the first three octets) and allows wildcard matching on any value in the fourth octet, which is specified as0
. Any port range that is specified for this virtual IP matches across all 254 IP addresses of the VIP.
- If multiple IP addresses are needed and are grouped into a subnet,
then a subnet mask can be applied to the base IP address. For example,
an entry of
- If VIP traffic is coming from a specific netmask, enter the mask value here.
-
Enter the start port value in the
Start Port
field and the end port value in theEnd Port
field. - From the Instance drop-down, select the DNCA instance to which to apply the rule.
- Click Create Filter.
-
The filter rule is added to the specified instance and
is immediately applied to incoming traffic.
Note: Only one port range filter rule should be added to each instance. Any additional port range rules for the instance are ignored.Note: After you save changes in the Interface tab, a manual restart of the DNCA is required. See DNCA web Console - Console Tab.
