Here are the useful terms related to packet rules.
- border
- Border is a public address that forms a border between a trusted and an untrusted network. It describes the IP address as an actual interface on the iSeries™ server. The system needs to know the "type" of address you are defining. For example, your personal computer's IP address is trusted, but your server's public IP address is border.
- firewall
- A logical barrier around systems in a network. A firewall consists of hardware, software, and a security policy that controls the access and flow of information between secure (trusted) systems and nonsecure (untrusted) systems.
- maxcon
Maxcon is a parameter, which is part of masquerade network
address translation (NAT) filter rule. It is the number of conversations that
can be active at one time. You are required to define this number when you
set up NAT masquerade rules. The default value is 128. Maxcon only pertains
to masquerade NAT rules.
- NAT conversation
- A NAT conversation is a relationship between any of the following IP addresses
and port numbers:
- Private source IP address and source port number (without NAT)
- Public (NAT) source IP address and public (NAT) source port number
- Destination IP address and port number (an external network)
- PPP filter identifier
- A PPP filter identifier allows you to apply filter rules to an interface that has been defined in a point-to-point profile. The PPP filter identifier also links the filter rules to groups of users in a point-to-point profile. Because the point-to-point profile is associated with a specific IP address, the filter identifier implicitly defines the interface to which the rules apply. To learn more, see this scenario, Manage remote user access to resources using Group Policies and IP filtering in the Remote Access Services: PPP connections topic.
- timeout
- Timeout controls the amount of time a conversation is allowed to last. If you have timeout set too short, the conversation is stopped too quickly. The default value is 16.
