IPMaps

IPMaps supports one-to-one Network Address Translation (NAT) for IP addresses assigned to servers,
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 support other devices on the LAN.
These devices utilize Motorola Netopia®'s default NAT/PAT capabilities.

FAQs for the IPMaps Feature

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

What are IPMaps and how are they used?

The IPMaps feature allows multiple static WAN IP
addresses to be assigned to the Motorola Netopia® Gateway.
Static WAN IP addresses are used to support specific services, like a web server, mail server, or DNS
server. 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 servers are supported 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 served
IP address for the NAT table.

What types of servers are supported by IPMaps?

IPMaps allows a Motorola Netopia® Gate-
way to support servers behind the Gateway, for example, web, mail, FTP, or DNS servers. VPN servers are
not supported at this time.

Can I use IPMaps with my PPPoE or PPPoA connection?

Yes. IPMaps can be assigned to
the WAN interface provided they are on the same subnet. Service providers will need to ensure proper
routing to all IP addresses assigned to your WAN interface.
Will IPMaps allow IP addresses from different subnets to be assigned to my Gate-

way?

IPMap will support statically assigned WAN IP addresses from the same subnet.
WAN IP addresses from different subnets are not supported.
