refer to Section 6.4.1. Note that when defining a network connection as DMZ, you must also:
• Remove the connection from under a bridge, if that is the case.
• Change the connection’s routing mode to “Route”, in the ‘Routing’ sub-tab.
• Add a routing rule on your external gateway (which may be supplied your ISP), informing of
the DMZ network behind iPECS SBG-1000.
MTU MTU is the Maximum Transmission Unit. It specifies the largest packet size permitted for
Internet transmission. In the default setting, Automatic, the gateway selects the best MTU for
your Internet connection. Select ‘Automatic by DHCP’ to have the DHCP determine the MTU. In
case you select ‘Manual’ it is recommended to enter a value in the 1200 to 1500 range.
Internet Protocol Select one of the following Internet protocol options from the ‘Internet Protocol’
drop-down menu:
• Obtain an IP Address Automatically
• Use the Following IP Address
Note that the screen refreshes to display relevant configuration settings according to your choice.
Obtain an IP Address Automatically Your connection is configured by default to obtain an IP
automatically. You should change this configuration in case your service provider requires it. The
server that assigns the gateway with an IP address, also assigns a subnet mask. You can override
the dynamically assigned subnet mask by selecting the ‘Override Subnet Mask’ and specifying
your own mask instead.

Use the Following IP Address Your connection can be configured using a permanent (static) IP
address. Your service provider should provide you with such an IP address and subnet mask.

server address, or specify such an address manually, according to the information provided by
your ISP. To configure the connection to automatically obtain a DNS server address, select ‘Obtain
DNS Server Address Automatically’ from the ‘DNS Server’ drop down menu.
