Obser ve the following guidelines when using Network Address Translation.
■
The router can expor t only one local IP address per UDP/TCP por t, so you can have just one machine
available for a given ser vice, such as one FTP ser ver. However, some ser vices, such as Web ser vers
(www-http ser vers), allow you to change the UDP/TCP por t on both the ser ver and client. With two different
UDP/TCP por ts expor ted, you can have Web ser vers 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 primar y Domain Name Ser ver (DNS) with whichever profile is more accessible. If you
choose for neither profile to be “dial-on-demand,” you can associate a secondar y DNS with the other
profile. See
below, for more information on these settings.
