Filtering by Port

Filtering by port is useful in many different troubleshooting and security monitoring

scenarios. The Port Filter rule lets you filter by either source or destination port, or traffic

moving between specific source and destination ports.

Filtering by Protocol Data fields

Observer’s Protocol Data Field filter rule lets you search for specific values in selected

protocol header fields. For example, you can filter for ICMP “destination unreachable”

packets, as well as wireless control, data, and management packets, to name but two. You

can also define your own custom protocol filter, either by port or search pattern.

Choose IP-TCP, IP-UDP, or IPX.

Select a port or range of ports to filter for.

Select what direction you want to filter for. If the “other port”

option is left unchecked, Observer filters for packets to or

from any port to the given port.

By checking the “other port” box, you can specify a second

port, allowing you to filter for traffic between specific source

and destination ports in both directions.

Select one of the pre-defined protocol filters from the

protocol selection tree, or select “User Defined” to

create a custom protocol filter using a Port or Pattern

rule.

Lets you add, edit, or delete user defined protocols.
