Network Address Translation guidelines

Observe the following guidelines when using Network Address Translation.
The router can export only one local IP address per UDP/TCP port, so you can have just one machine
available for a given service, such as one FTP server. However, some services, such as Web servers
(www-http servers), allow you to change the UDPTCP port on both the server and client. With two different
UDP/TCP ports exported, you can have Web servers on two different IP hosts.
If you will be using multiple connection profiles, define the remote IP address of the most accessible
profile, such as that for your ISP, to the default IP gateway in the TCP/IP settings on users' workstations.
That way, IP traffic not intended specifically for any of the remote networks will be routed through this
"preferred" profile.
Associate your primary Domain Name Server (DNS) with whichever profile is more accessible. If you
choose for neither profile to be "dial-on-demand," you can associate a secondary DNS with the other
profile. See "IP setup,"
WAN Configuration
below, for more information on these settings.
