Address Translation 6-23
Please also note the following:
The “best guess” LAN workstation will continue to receive all non-addressed
packets 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 the
remote workstation to the newly chosen “best guess” LAN workstation.
The LAN workstation previously selected to receive all non-addressed
packets from the remote workstation no longer receives them.
Use the following command to configure Intelligent PAT:
set vc <vc name> intelligent_pat_option <Enable/Disable>
Monitoring PAT The PAT configuration is displayed when viewing the remote site configuration
using the show vc command. The Network Address Translation field should
indicate “port (PAT)”. The PAT Default Address field will contain 0.0.0.0 if the
option is disabled, or a valid workstation IP address on the local LAN if it is
enabled. The static and/or dynamic address definitions are appended to the
display only when configured.
When the remote site is active, current port mappings and address mappings
are displayed with the following commands, respectively:
list nat vc <vc name> port
list nat vc <vc name> addr
Network Address
Translation (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 PAT
If you simply use the add vc <vc name> command without specifying a NAT
option, the default is NAT disabled (meaning that NAT, PAT, and Super NAT are
not enabled).
Enabling NAT
To enable NAT, enter the following command:
set vc <vc name> nat_option nat
