Add IPSec proposal
You can add up to four IPSec proposals.You determine the encryption method, the
authentication methods, how long a single set single set of cryptographic keys is used when
applying VPN services to IP packets and the order this proposal is in the list.
Field Description
Encryption
Select one of the following types:
●
DES. A common encryption algorithm not subject to export
regulation.
●
3DES. A robust encryption algorithm.
● AES-128. The advanced encryption standard that uses a
128-bit block to help resist large attacks.
● Any. Accepts any encryption proposal made by the device
on the other side.
Authentication
Select one of the following types:
● Any. Accepts any authentication proposal that is made by
the device on the other side.
● None
●
HMAC-MD5
● HMAC-SHA
Compression
Select one of the following types:
● None
●
LZS
The security gateway supports IP payload compression using
IPCOMP. Use of the LZS parameter improves usage of bandwidth
and throughput. This is the default configuration.
This parameter applies to VPN traffic only.
