Default Action Packets that do match any of the Filters Classes are handled according to the
Default Action.
Select Forward All or Block All as the filter's default action. The filter's default
action must be the opposite of the action for at least one of the addresses in the
filter.
For example, if you create a filter containing an IP address, an IP protocol, and an
TCP/UDP port, and you select Block as the action for all of them, you must choose
Forward All as the filter's default action.
Destination Address This is where you identify the destination IP address you want to filter.
If you plan to block traffic to all IP addresses except those you specify as allowed,
put the address of your own PC in the list of allowed addresses to avoid losing
connectivity to the access point.
Source Address This is where you identify the source IP address you want to filter.
If you plan to block traffic to all IP addresses except those you specify as allowed,
put the address of your own PC in the list of allowed addresses to avoid losing
connectivity to the access point.
Mask Type the mask for the destination IP address. Enter the mask with periods
separating the three groups of four characters, for example,112.334.556.778.
• If you enter 255.255.255.255 as the mask, the access point accepts any IP
address.
• If you enter 0.0.0.0, the access point looks for an exact match with the IP
address you entered in the IP Address field.
The mask you enter in this field behaves the same way that a mask behaves when
you enter it in the CLI.
IP Protocol This is where you can filter an IP protocol. Select one of the common protocols
from the pull-down menu or click Custom and enter the number of an existing
ACL in the Custom field.
Enter an ACL number from 0… 255.
TCP Port This is where you can filter a TCP protocol. Select one of the common port
protocols from the pull-down menu or select the Custom radio button and enter
the number of an existing protocol in one of the Custom fields.
Enter a protocol number from 0…65535.
UDP Port This is where you can filter a UDP protocol. Select one of the common port
protocols or check the Custom radio button and enter the number of an existing
protocol in one of the Custom fields.
Enter a protocol number from 0… 65535.
Filters Classes The protocols appear on this portion of the page.
To remove the protocol from the Filters Classes list, select it and click Delete Class.
