IPSec Setup
NOTE The configuration on the remote router should be the same as the local
router.
Keying Mode: Manual: Choose if you want to configure a self-
defined key without negotiation. Encryption key and
Authentication key will be used to verify remote users.

by a pre-shared key, and negotiates the second key in

• Manual mode
Be sure to enter the same settings when configuring the other end router for
this tunnel.
Incoming SPI: Input a number between 100~ffffffff as SPI (Security
Parameter Index). SPI is an identification tag for an
IPSec association. The incoming SPI of this router
should be the same as the outgoing SPI at the other
end of the tunnel.
Outgoing SPI: Input a hexadecimal number between 100~ffffffff as
SPI. The outgoing SPI of this router should be the same
as the incoming SPI at the other end of the tunnel.
Encryption: DES or 3DES.
Authentication: MD5 or SHA1.
Encryption Key: Input 16 numbers for DES method or 48 numbers for
3DES method.
If you enter less than required values, zeroes will be
filled in to empty spaces.
Example: If you enter 12345678 for DES encryption,
the box will show “1234567800000000.”
