Q1: How do I configure the end IP address of the DHCP server address pool on the UTT Router?
A1: On the UTT Router, DHCP server address pool range is determined by the parameters Start IP Address andNumber of Addresses. For example, if Start IP Address is 192.168.16.2, and Number of Address is 62, then the DHCP address pool is 192.168.16.2 to 192.168.0.63.
Q2: On my internal network, a computer’s IP address is manually set to 192.168.16.3. Now I want to enable DHCP server on my router, and its Start IP Address is 192.168.16.2, Number of Addresses is 62. Does this cause an IP address conflict on my network?
A2: The UTT Router provides IP address conflict detection feature. The DHCP server will attempt to determine whether the IP address is already in use before assign it to a client. When the DHCP server detects that an IP address is being used, it will not assign that address to any client to avoid address conflict. However, there is no guarantee that the manually configured computer is currently connected to the network or available to respond when the DHCP server is verifying its IP address. Therefore, the DHCP server may assign the IP address to a DHCP client. When the manually configured computer connects to the network, there will be an IP address conflict on your network.
Q3: I want to use DHCP on my network, but there are some devices that require a static IP address. How to avoid IP address conflict?
A3: To avoid IP address conflict, we suggest that you manually configure those devices to have an IP address that is outside of the DHCP address pool; however, if a device has been manually configured with an IP address in the DHCP address pool, and you don’t want to change the IP address, you can create a DHCP manual binding for the device.
Q4: I have two Internet connections (both have 5Mbps bandwidth) on my HiPER 2620 router. Will this double my Internet bandwidth and download speed?
A4: When using multiple Internet connections, the HiPER 2620 will balance the traffic among them based on IP address or NAT session. If Load Balancing Policy is NAT Session (default value), you may get double bandwidth and download speed at some computers. However, if you change Load Balancing Policy to IP Address, in general, you may not get double bandwidth and download speed.
Q5: Why I cannot access online banking after using two Internet connections on my router?
A5: This is because that, if you use multiple Internet connections, Load Balancing Policy is NAT Session by default, that is, the NAT sessions of the same application will be assgined to different connections, thus some applications (likeonline banking, QQ, etc.) cannot run properly due to the identity change. To resolve this problem, you need to configure the router to assign the NAT sessions of the same application to the same Internet connection, either by changing change Load Balancing Policy to IP Address in Basic > Load Balancing > Global Settings page, or selectingEnable ID Binding check box in Basic > Load Balancing > ID Binding page.
