9-28 MAX 6000/3000 Network Configuration Guide
Configuring IP Routing
Configuring system-level routing policies
5 To ensure that all incoming sessions are routed to the default server, open each Ethernet >
NAT > NAT > Static Mappings > Static Mapping NN subprofile (where NN is a number
from 1 to 10) and make sure that the Valid parameter in each subprofile is set to No.
6 Set the Def Server parameter to the IP address of the server, on the local network, that is to
receive all incoming packets from the remote network.
7 Exit the profile and, at the exit prompt, select the exit and accept option.
The changes take effect the next time a connection specified in the NAT profile is established.
To activate the changes immediately, close the connection specified by the Profile parameter
and then reopen it.
Routing incoming sessions to up to ten servers on the private LAN
To configure the MAX to perform NAT and to define up to ten servers, and optionally a default
server, to handle sessions initiated by callers from outside the private LAN:
1 Open the Ethernet > NAT > NAT profile.
2 Set the Routing parameter to Yes.
3 Set the Profile parameter to the name of an existing Connection profile.
The MAX performs NAT whenever a connection is made with this Connection profile.
The connection can be initiated either by the MAX or by the remote network.
4 Set the Lan parameter to Single IP Addr.
5 Open the Ethernet > NAT > NAT > Static Mappings profile.
6 Open a Static Mapping NN subprofile, where nn is a number from 1 to 10.
You use the parameters in each Static Mapping NN subprofile to specify routing for
incoming packets sent to a particular TCP or UDP port.
7 Set the Valid parameter to Yes.
This setting enables the port routing specified by the remaining parameters in the
subprofile. Setting this parameter to No disables routing for the specified port.
8 Set the Dst Port # parameter to the number of a TCP or UDP port that users outside the
private network can access.
Each Dst Port # setting corresponds to a service provided by a server on the local private
network. You can use the actual port number as specified by the Loc Port # parameter as
long as that address is unique for the local private network. For information about
obtaining port numbers, see “Configuring WAN interfaces” on page 9-31.
The MAX routes incoming packets for this port to the local server and port you are about
to specify.
9 Set the Protocol parameter to TCP or UDP.
This parameter determines whether the Dst Port # and Loc Port # parameters specify TCP
ports or UDP ports.
10 Set the Loc Port # to a port corresponding to a service provided by the local servers.
11 Set the Loc Adrs parameter to the address of the local server providing the service
specified by Loc Port #.
12 Exit and save the profile.
Repeat step 6 through step 12 for any additional ports whose packets you want to route to
a specific server and port on the local network.
