18 In the Default Workstation for Incoming Packets field, specify the workstation to
which all unsolicited TCP/UDP packets should be delivered. Choose None to have
unsolicited packets simply dropped.
19 In the Enable Intelligent NAT field, leave the default set to Yes.
20 Click Submit.
If you would like to configure a connection to another server LAN Modem, repeat
steps 1 through 20.
If you will be accessing a LAN Modem server from a LAN Modem client via the
Single-User dial-in scenario, you must manually change the IP address of the client
LAN Modem in order to distinguish between the two networks. This is required
because by default the subnet addresses for both LAN Modems are the same
(192.168.1.x).
Note that this change occurs automatically when creating a LAN Modem
Site-to-Site profile via the Dial-in Wizard, but will not automatically occur when
creating a Single-User profile.
To change the IP address of the client LAN Modem which will dial into the server
LAN Modem, do the following.
1 Access the LAN Parameters page on the LAN Modem which will be placing the
outgoing call by clicking the LAN Modem icon on the main page.
The LAN (Ethernet) Parameters page opens.
2 Change the IP address field to 192.168.2.1.
3 Click Submit.
The LAN Modem re-initializes itself. The front panel LEDs flash, indicating a rest in
progress.
Once the LAN Modem IP address has been changed, you can no longer access the
LAN Modem until your workstation has been restarted and has acquired an IP
address belonging to the new LAN Modem subnet.
4 Restart your workstation.
The default IP address for the local LAN Modem will have been changed to
192.168.2.1. Similarly, all attached workstations, once restarted, will utilize an IP
address belonging to this new subnet (192.168.2.x).
