4.18.2 Configuring the IPSec function
Step 1 Choose Advanced Setup > IPSec to enter the configuration page, and click Add New
Connection.
Step 2 Enter an IPSec connection name, which is IPSec_1 in this example.
Step 3 Enter the IP version, which is IPv4 in this example.
Step 4 Select a local gateway interface, which is ipoe_LAN1/eth3.1 in this example.
Step 5 Enter a remote IPSec gateway address, which is 210.76.200.101 in this example.
Step 6 Set Tunnel access from local IP address to Subnet, and set a local network segment which
is 192.168.1.0 and 255.255.255.0 in this example.
Step 7 Set Tunnel access from remote IP address to Subnet, and set a local network segment of
the peer router which is 192.168.0.0 and 255.255.255.0 in this example.
Step 8 Enter a Pre-Shared key which is 12345678 in this example. And leave other parameters
unchanged.
Step 9 Click Apply/Save.
