9-26 MAX 6000/3000 Network Configuration Guide
Configuring IP Routing
Configuring system-level routing policies
Configuring single- or multiple-address NAT
To configure NAT on the MAX:
1Open the Ethernet > NAT > NAT profile. For example:
NAT
50-C01 NAT...
Routing=Yes
Profile=NATprofile
Lan=Single IP addr
FR address=10.10.10.10
Static Mappings...
Def Server=N/A
Reuse last addr=N/A
Reuse addr timeout=N/A
2Enable NAT by setting the Routing parameter to Yes. W ithout this setting, no other setting
is valid.
3Set the Profile parameter to specify the name of the Connection profile in which you want
to use NAT.
4If applying NAT to Frame Relay connections, set FR Address and other parameters as
described in “NAT for Frame Relay” on page 9-26.
5Optionally, configure NAT port routing in the Static Mapping NN subprofiles, as
described in “Configuring NAT port routing (Static Mapping subprofiles)” on page 9-27.
6Optionally, set Def Server to the IP address of a local server to which the MAX routes
incoming packets that are not routed to a specific server and port. (For more information,
see “Routing all incoming sessions to the default server” on page 9-27.)
7Optionally, set Reuse Last Addr to Yes to continue to use a dynamically assigned IP
address. The Reuse Addr Timeout value specifies the time for which to use the address.
Set it to a number of minutes (up to 1440). Limitations apply, as described in the MAX
Reference.
8Exit the profile and, at the exit prompt, select the exit and accept option.
Note: If you have additional routers on your Local Area Network, open Ethernet > Mod
Config > Ether Options, and set the value of Ignore Def Rt to Yes. This setting avoids the
possibility that a default route from the ISP overwrites the NAT route.
NAT for Frame Relay
The single-IP address implementation of NAT extends to Frame Relay. For connections using
Frame Relay encapsulation, a MAX running single-IP address NAT translates the local
addresses into a single, official address specified by the FR Address parameter. You must set
the Routing parameter in the NAT profile to enable NAT, set the Lan parameter to Single IP
Addr, and set FR Address to a valid, official IP address. For example:
50-C00 NAT
50-C01 NAT...
Routing=Yes
Profile=max4
Lan=Single IP addr
FR address=10.10.10.10
Static Mapping...
Def Server=181.81.8.1
