IP setup | Netopia 4542, 4541 instruction

Multiple Network Address Translation 9-7

You can conﬁgure a simple 1-to-many PAT (often referred to simply as NAT) mapping using Easy Setup. More complex setups require conﬁguration using the Network Address Translation item on the IP Setup screen.

An example MultiNAT conﬁguration at the end of this chapter describes some applications for these features. See the MultiNAT Conﬁguration Example on page 9-26.

In order to conﬁgure the router to make servers on your LAN visible to the Internet, you use advanced features in the System Conﬁguration screens, described in IP setup.
