EMG6765-Q10A User’s Guide

The actual physical connection determines whether the EMG6765-Q10A ports are LAN or WAN ports. 
There are two separate IP networks, one inside the LAN network and the other outside the WAN network 
as shown next.

Figure 48   LAN and WAN IP Addresses

The LAN parameters of the EMG6765-Q10A are preset in the factory with the following values:

• IP address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits)
• DHCP server enabled with 32 client IP addresses starting from 192.168.1.33. 

These parameters should work for the majority of installations. If your ISP gives you explicit DNS server 
address(es), read the embedded Web Configurator help regarding what fields need to be configured.

The EMG6765-Q10A is pre-configured with a pool of 32 IP addresses starting from 192.168.1.33 to 
192.168.1.64. This configuration leaves 31 IP addresses (excluding the EMG6765-Q10A itself) in the lower 
range (192.168.1.2 to 192.168.1.32) for other server computers, for instance, servers for mail, FTP, TFTP, 
web, etc., that you may have.

The EMG6765-Q10A has built-in DHCP server capability that assigns IP addresses and DNS servers to 
systems that support DHCP client capability.

IP alias allows you to partition a physical network into different logical networks over the same Ethernet 
interface. The EMG6765-Q10A supports three logical LAN interfaces via its single physical Ethernet 
interface with the EMG6765-Q10A itself as the gateway for each LAN network.
