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.
