DEFINE
Creates or deletes a packet filter, or configures a rule in that filter that is used to manage network traffic.
These packet filters are applied to packets arriving from or going to remote dialup sites.
Each rule consists of a name, a position, an action (allow or deny) and a protocol segment. To configure
protocol options, refer to the appropriate command on the following pages. Due to space considerations, the
command syntax from the Add braces to the Allow/Deny braces in the above diagram is represented by an
ellipse (...) in the remaining Set/Define Filter commands.
In-depth protocol-related examples are given with the subcommands listed on the following pages.
