IPMaps suppor ts one-to-one Network Address Translation (NAT) for IP addresses assigned to ser vers, 
hosts, or specific computers on the LAN side of the Motorola Netopia® Gateway. 

A single static or dynamic (DHCP) WAN IP address must be assigned to suppor t other devices on the LAN. 
These devices utilize Motorola Netopia®’s default NAT/PAT capabilities.

Before configuring an example of an IPMaps-enabled network, review these frequently asked questions. 

The IPMaps feature allows 

multiple static WAN IP 

addresses to be assigned to the Motorola Netopia® Gateway. 

Static WAN IP addresses are used to suppor t specific ser vices, like a web ser ver, mail ser ver, or DNS 
ser ver. This is accomplished by mapping a separate static WAN IP address to a specific internal LAN IP 
address. All traffic arriving at the Gateway intended for the static IP address is transferred to the internal 
device. All outbound traffic from the internal device appears to originate from the static IP address. 

Locally hosted ser vers are suppor ted by a public IP address while LAN users behind the NAT-enabled IP 
address are protected.

IPMaps is compatible with the use of NAT, with either a statically assigned IP address or DHCP/PPP ser ved 
IP address for the NAT table.

IPMaps allows a Motorola Netopia® Gate-

way to suppor t ser vers behind the Gateway, for example, web, mail, FTP, or DNS ser vers. VPN ser vers are 
not suppor ted at this time.

Yes. IPMaps can be assigned to 

the WAN inter face 

provided they are on the same subnet. Service providers will need to ensure proper 

routing to all IP addresses assigned to your WAN inter face.

IPMap will suppor t statically assigned WAN IP addresses from the 

same subnet.

WAN IP addresses from different subnets are 

not supported.
