Setting the Local and Remote Gateway Address for Port Prefixes
This section describes how to set the optional local and remote gateway addresses for 
ports that are providing a network-to-network connection. Local and remote gateway 
addresses are used in conjunction with the egress address translation feature (see 
page 16-12).
Figure 17-24 shows which addresses to enter as the local and remote gateway 
addresses for each end of the network-to-network connection.
Figure 17-24. Setting Local and Remote Gateway Addresses
You can configure prefixes on a network-to-network port with the following 
addresses:
• Null local and remote gateway addresses
• Only a local gateway address
• Only a remote gateway address
• Both a local and a remote gateway address
