Address Translation 6-23Please also note the following: The “best guess” LAN workstation will continue to receive all non-addressedpackets sent by this remote workstation until and unless a new (different)communication pattern is detected by Intelligent PAT. When a new communication pattern is detected, Intelligent PAT makes a new“best guess”, with the following results: Intelligent PAT begins to forward all non-addressed packets sent by theremote workstation to the newly chosen “best guess” LAN workstation. The LAN workstation previously selected to receive all non-addressedpackets from the remote workstation no longer receives them.Use the following command to configure Intelligent PAT:set vc intelligent_pat_option Monitoring PAT The PAT configuration is displayed when viewing the remote site configurationusing the show vc command. The Network Address Translation field shouldindicate “port (PAT)”. The PAT Default Address field will contain 0.0.0.0 if theoption is disabled, or a valid workstation IP address on the local LAN if it isenabled. The static and/or dynamic address definitions are appended to thedisplay only when configured. When the remote site is active, current port mappings and address mappingsare displayed with the following commands, respectively:list nat vc portlist nat vc addrNetwork AddressTranslation (NAT)NAT maps one private LAN IP address (one user) to one public (WAN) IP address.When using NAT, multiple users can access a single application at the same time.Configuring NAT When you create a vc using QuickVC, you are asked if you want to enable PAT.During QuickVC setup, you can: Accept the default choice (YES) to enable nat_option PAT. Choose not to enable PATIf you simply use the add vc command without specifying a NAToption, the default is NAT disabled (meaning that NAT, PAT, and Super NAT arenot enabled).Enabling NATTo enable NAT, enter the following command:set vc nat_option nat
