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 as 0.
Any port range that is specified for this virtual IP matches across
all 254 IP addresses of the VIP.
-
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 the End 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.
