SOURCE NAT CONFIGURATION
Source NAT (SNAT) is mainly used for changing the source address of packets. A
good example would be that of a network behind a firewall, which interacts with
the external world. For the hosts behind the firewall to interact with the external
world, the local network's IP addresses have to be substituted with that of the
firewall.
With this target, the firewall will automatically SNAT and De-SNAT the packets,
hence making it possible to make connections from the LAN to the Internet.
Refer the following section to configure SNAT on your system:
• “SNAT Configuration Steps”
• “SNAT Configuration Flow”
• “SNAT Configuration Commands”
• “Sample Configurations of SNAT on OmniAccess 5740 USG”
