LABEL DESCRIPTION
Metric 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 Enter the maximum amount of traffic, in kilobits per second, the UAG can send through
Bandwidth
the interface to the network. Allowed values are 0 - 1048576.
Ingress This is reserved for future use.
Bandwidth
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 Enter the IP address from which the UAG begins allocating IP addresses. If you want to
Address
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.
First DNS Server Specify the IP addresses up to three DNS servers for the DHCP clients to use. Use one
Second DNS
of the following ways to specify these IP addresses.
Server
Third DNS
Custom Defined - enter a static IP address.
Server
From ISP - select the DNS server that another interface received from its DHCP server.
Device - the DHCP clients use the IP address of this interface and the UAG works as a
DNS relay.
