86 CHAPTER 5: CONFIGURING THE ROUTER Dynamic/Fixed IP in 1483 Bridge Mode Dynamic/Fixed IP in 1483 Bridge Mode uses the same encapsulation as 1483 Bridging but with bridging function disabled. DHCP client function can also be enabled to obtain an IP address dynamically. Figure 65 Dynamic/Fixed IP in 1483 Bridge Mode Screen 1 Select Dynamic/Fixed IP in 1483 Bridge Mode from the protocol drop-down menu. 2 Enter your IP address, subnet mask, and default gateway information. 3 IPoEoA NAT IP - enter the IP address in this field. IPoE over AAL5 (IPoEoA) adopts a three-layer architecture, with IP encapsulation at the uppermost layer, IP over Ethernet (IPoE) in the middle, and IPoEoA at the bottom. When a device is connected to a remote access server at high speed to access an external network, PVC over ATM is used because of the long distance. In this case, it is required for the ATM port of the server to carry Ethernet packets, which is known as IPoEoA. In the application of IPoEoA, one virtual Ethernet (VE) interface can be associated with multiple PVCs. PVCs associated with the same VE interface are interconnected at layer 2. 4 If your ISP provides DNS information, check the DNS Automatic from ISP box. 5 If the ISP requires you to input a Host Name, enter it in the Host Name field.

Dynamic/Fixed IP in 1483 Bridge Mode uses the same encapsulation as
1483 Bridging but with bridging function disabled. DHCP client function
can also be enabled to obtain an IP address dynamically.

IPoEoA NAT IP - enter the IP address in this field.
IPoE over AAL5 (IPoEoA) adopts a three-layer architecture, with IP
encapsulation at the uppermost layer, IP over Ethernet (IPoE) in the
middle, and IPoEoA at the bottom. When a device is connected to a
remote access server at high speed to access an external network, PVC
over ATM is used because of the long distance. In this case, it is required
for the ATM port of the server to carry Ethernet packets, which is known

can be associated with multiple PVCs. PVCs associated with the same VE
interface are interconnected at layer 2.
