STEP SEVEN
NAT parameters will now be determined for routing outside of the local LAN. Network Address Translation maps the local IP addresses, registered in the local address range menu below, to the one global IP address assigned by the access provider. Local IP addresses not indicated in this menu will be discarded.
Menu CONFIG =>SECURITY =>NAT =>LOCAL ADDRESS =>ADD RANGE
Parameter | Example | Your Application |
First IP Address | 192.168.0.10 |
|
Last IP Address | 192.168.0.30 |

FIGURE 4.8 NAT LOCAL ADDRESS RANGE MENU PARAMETERS
The factory preset values for all other NAT parameters are appropriate for this example.
STEP EIGHT
Now that the parameters have been defined, enter into each menu described above, in the order presented (read chapter 3, Using Menus, if you have not done so already). Set the parameters in each menu according to the values you wrote in the figures above. Save the configuration to flash memory at each step when requested — configurations saved in run memory are erased when the router is turned off. If you saved part of the configuration to run memory for some reason, save to flash memory now using the menu option ADMIN =>WRITE CONFIGURATION =>TO FLASH.
STEP NINE
The Ethernet interface can be tested as described in the troubleshooting appendix. The SWAN interface can be tested in a similar manner. At this point, you should create a backup of the configuration file (in binary) and print out a listing of the configuration.
