Configuring a Manual Key VPN

System > Network > VPN > IPSec VPN

Users can configure the IPSec VPN by using the manual key VPN method.

In the Manual Key VPN Configuration section in the IPSec VPN page, you can perform the following actions:

Options in the Manual Key VPN Configuration page:

Option Description
Basic
Tunnel Name

Specifies or displays the name of manually created key VPN.

Mode

Specifies the mode, including Tunnel and Transport. The tunnel mode is the default mode.

Peer IP

Specifies the IP address of the peer.

Local SPI

Type the local SPI value. SPI is a 32-bit value transmitted in AH and ESP header, which uniquely identifies a security association. SPI is used to seek corresponding VPN tunnel for decryption.

Remote SPI

Type the remote SPI value.

Note: When configuring an SA, you should configure the parameters of both the inbound and outbound direction. Furthermore, SA parameters of the two ends of the tunnel should be totally matched. The local inbound SPI should be the same with the outbound SPI of the other end; the local outbound SPI should be the same with the inbound SPI of the other end.

Interface

Specifies the egress interface for the manual key VPN. Select the interface you want from the drop-down list.

Encryption
Protocol

Specifies the IPSec type. ESP is the default type.

Encryption

Specifies the encryption algorithm. 3DES is the default encryption algorithm.

Inbound Encryption Key

Type the encryption key of the inbound direction. You should configure the keys of both ends of the tunnel. The local inbound encryption key should be the same with the peer's outbound encryption key, and the local outbound encryption key should be the same with the peer's inbound encryption key.

Outbound Encryption Key

Type the encryption key of the outbound direction.

Hash

Specifies the authentication algorithm. SHA-1 is the default authentication algorithm.

Inbound Hash Key

Type the hash key of the inbound direction. You should configure the keys of both ends of the tunnel. The local inbound hash key should be the same with the peer's outbound hash key, and the local outbound hash key should be the same with the peer's inbound hash key.

Outbound Hash Key

Type the hash key of the outbound direction.

Compression

Select a compression algorithm. By default, no compression algorithm is used.
