Packet mappings

Although packet mappings are defined to a SafeLinx Server, packet mappings are expressly used by mobile access services.

Packet mapping is a resource that is assigned to an MNI. A packet mapping is a way to redirect some types of traffic through a specified subnetwork that is represented by an MNI. You can create packet mappings for four types of packets:
  • TCP
  • UDP
  • ICMP
  • Other

You can use packet mappings to modify some fields within the header of a packet. For example, you can set up a mapping to change the port number on outgoing TCP packets to a port on a mail server that is optimized for SafeLinx Clients.
