Napt; Masquerading - NetModule NB3710 User Manual

5.5.4. NAPT

This page can be used to configure Network Address and Port Translation (NAPT) for
packets traversing the system. NAPT hereby modifies IP addresses or/and TCP/UDP
ports in matching IP packets. By tracking those connections, it will also automatically
adjust the returning packets of an IP session.
The administration page lets you specify the interfaces on which masquerading will be
performed. NAT will hereby use the address of the selected interface and choose a
random source port for outgoing connections and thus enables communication between
hosts from a private local area network towards hosts on the public network.
