6.3.10. LAN IP configuration
Enter the LAN IP Address, Gateway IP Address and DHCP Server Configuration using
this screen. The OmniConnect series access devices use default IP address of 192.168.1.1 for
their LAN IP Address and Gateway IP Address. For most applications, the default values of
these parameters will not need to be changed. We recommend that both of these values
remain at their default values. If, however, it is necessary to alter these defaults, deselect the
Default check box and enter the IP Address, IP Subnet Mask and Gateway IP Address
Configuration parameters.
The Gateway IP Address parameter normally must be the same as the IP Address
parameter. Normally, the OmniConnect modem access device is the Gateway for its clients as
well as the DHCP server. In the case that the OmniConnect access device is used as a DHCP
server and not as the outgoing Gateway, the Gateway IP Address parameter should be
changed to that of the outgoing gateway. The DHCP Server will then assign the Gateway
Address to each of its clients. The Gateway IP Address and the LAN IP Address should
normally be attached to the same subnetwork.
The DHCP Server Configuration allows the enabling or disabling of the built-in DHCP
server. The OmniConnect access devices can act as a complete DHCP server, assigning all the
IP addresses to all the local computers connected on the LAN. Checking the DHCP Server
Enable check box and entering a Starting IP Address and Number of Addresses count enables
this feature. Checking the DHCP Server Disable check box disables the feature.
The DHCP server automatically assigns an IP subnet mask to its clients based upon the setting
of the Number of Addresses parameter. The mask is calculated according to the following
table.
