Chapter 8 Interfaces Table 51 Configuration > Network > Interface > Bridge > Edit (continued) LABEL Ingress Bandwidth MTU DHCP Setting DHCP DESCRIPTION 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. 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. 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. Relay Server 1 Relay Server 2 IP Pool Start Address 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. Enter the IP address of a DHCP server for the network. 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. 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. Pool Size 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. 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 Second DNS Server Third DNS Server Specify the IP addresses up to three DNS servers for the DHCP clients to use. Use one of the following ways to specify these IP addresses. Custom Defined - enter a static IP address. From ISP - select the DNS server that another interface received from its DHCP server. First WINS Server, Second WINS Server Default Router Device - the DHCP clients use the IP address of this interface and the UAG works as a DNS relay. Type the IP address of the WINS (Windows Internet Naming Service) server that you want to send to the DHCP clients. The WINS server keeps a mapping table of the computer names on your network and the IP addresses that they are currently using. If you set this interface to DHCP Server, you can select to use either the interface's IP address or another IP address as the default router. This default router will become the DHCP clients' default gateway. To use another IP address as the default router, select Custom Defined and enter the IP address. 134 UAG715 User's Guide
