Configure TCP/IP

TCP/IP must be properly configured before operating your device over a network. Both IPv4 and IPv6 are available.

1. Go to System > Network > TCP/IP.
   Figure 1 TCP/IP Settings
2. Select Working Mode as Net-Fault Tolerance or Multi-Address Mode.

   Net-Fault Tolerance

   The two NIC cards use the same IP address, and you can select the main NIC to LAN1 or LAN2. In this way, in case of one NIC card failure, the device will automatically enable another standby NIC card so as to ensure the normal running of the system.

   Multi-Address Mode

   The parameters of the two NIC cards can be configured independently. You can select LAN1 or LAN2 under Select NIC for parameter settings. Select one NIC card as the default route. When the system connects with the extranet, the data will be forwarded through the default route.

3. Click IPv4 or IPv6 as you required.
4. Optional: Check Enable DHCP to obtain IP settings automatically if a DHCP server is available on the network.
5. Set related parameters.
   Note:

   Valid MTU value range is from 500 to 1500.

6. Click Apply.
