Chapter 10 Interfaces
UAG Series User’s Guide

Gateway This option appears when Interface Type is external or general . This field is enabled
if you select Use Fixed IP Address .
Enter the IP address of the gateway. The UAG sends packets to the gateway when it
does not know how to route the packet to its destination. The gateway should be on the
same network as the interface.
Metric This option appears when Interface Type is external or general . Enter the priority of
the gateway (if any) on this interface. The UAG decides which gateway to use based on
this priority. The lower the number, the higher the priority. If two or more gateways
have the same priority, the UAG uses the one that was configured first.
Interface
Parameters
Egress
Bandwidth
Enter the maximum amount of traffic, in kilobits per second, the UAG can send through
the interface to the network. Allowed values are 0 - 1048576.
Ingress
Bandwidth
This is reserved for future use.
Enter the maximum amount of traffic, in kilobits per second, the UAG can receive from
the network through the interface. Allowed values are 0 - 1048576.
MTU Maximum Transmission Unit. Type the maximum size of each data packet, in bytes, that
can move through this interface. If a larger packet arrives, the UAG divides it into
smaller fragments. Allowed values are 576 - 1500. Usually, this value is 1500.
DHCP Setting
DHCP Select what type of DHCP service the UAG provides to the network. Choices are:
None - the UAG does not provide any DHCP services. There is already a DHCP server
on the network.
DHCP Relay - the UAG routes DHCP requests to one or more DHCP servers you
specify. The DHCP server(s) may be on another network.
DHCP Server - the UAG assigns IP addresses and provides subnet mask, gateway, and
DNS server information to the network. The UAG is the DHCP server for the network.
These fields appear if the UAG is a DHCP Relay .
Relay Server 1 Enter the IP address of a DHCP server for the network.
Relay Server 2 This field is optional. Enter the IP address of another DHCP server for the network.
These fields appear if the UAG is a DHCP Server .
IP Pool Start
Address
Enter the IP address from which the UAG begins allocating IP addresses. If you want to
assign a static IP address to a specific computer, click
Add Static DHCP .
If this field is blank, the Pool Size must also be blank. In this case, the UAG can assign
every IP address allowed by the interface’s IP address and subnet mask, except for the
first address (network address), last address (broadcast address) and the interface’s IP
address.
Pool Size Enter the number of IP addresses to allocate. This number must be at least one and is
limited by the interface’s
Subnet Mask . For example, if the Subnet Mask is
255.255.255.0 and IP Pool Start Address is 10.10.10.10, the UAG can allocate
10.10.10.10 to 10.10.10.254, or 245 IP addresses.
If this field is blank, the IP Pool Start Address must also be blank. In this case, the
UAG can assign every IP address allowed by the interface’s IP address and subnet
mask, except for the first address (network address), last address (broadcast address)
and the interface’s IP address.
