114 CHAPTER 8: CONFIGURING THE DUAL 56K LAN MODEM FOR DIAL-IN SUPPORT 14 For Network Address Translation, your choice depends on the Dial-User Profile Type that you selected for this LAN Modem, as follows: s If you are configuring this LAN Modem for Single-User LAN Modem using NAT, leave NAT enabled. s If you are configuring this LAN Modem for LAN Site-to-Site, disable NAT. 15 Under WAN Link IP address, leave these fields blank. The LAN Modem will automatically assign these values upon connection. 16 Under Subnet Mask, leave these fields blank. The LAN Modem will automatically assign these values upon connection. 17 For Allow Automatic Call Initiation, leave the default setting which is Yes. If you select No, you will have to manually launch a call to this service provider every time you want to connect. You may want to change this field to No later on if you find that calls are being connected unintentionally as a result of packets generated by other computers on the LAN. 18 For Enable Intelligent NAT, leave the default setting. 19 In the Default Workstation for Incoming Packets field, specify the workstation to which all unsolicited TCP/UDP packets should be delivered. Note that if the Enable Intelligent NAT field is set to Yes, the LAN Modem first attempts to deliver the unsolicited TCP/UDP packets to the workstation that is currently communicating with the remote host that has generated these packets. Only if no such workstation is found are the packets delivered to the specified default workstation. 20 Click Submit. This completes the configuration of the LAN Modem as a client device. Configuring Dial-in User Parameters Once you have created a Dial-in User profile using the Dial-in Wizard, you can further define the dial-in user parameters using the Dial-in User Parameters page. You can also use this page to configure an Advanced Dial-in User profile, or to create any Dial-in User profile without the Dial-in Wizard. You can create a total of ten dial-in user profiles. If you have created ten profiles and would like to add a new user, you must delete one profile before adding the new one. To access Dial-in User profiles, do the following: 1 Click the Dial-in Users button. The Dial-in User Selection screen opens, as shown in Figure 67.
