LABEL DESCRIPTION
Content This field is disabled if the Peer ID Type is Any. Type the identity of the remote IPSec
router during authentication. The identity depends on the Peer ID Type.
If the UAG and remote IPSec router do not use certificates,
IPv4 - type an IP address; see the note at the end of this description.
DNS - type the domain name; you can use up to 31 ASCII characters including spaces,
although trailing spaces are truncated. This value is only used for identification and can
be any string.
E-mail - the remote IPSec router is identified by the string you specify here; you can
use up to 31 ASCII characters including spaces, although trailing spaces are truncated.
This value is only used for identification and can be any string.
If the UAG and remote IPSec router use certificates, type the following fields from the
certificate used by the remote IPSec router.
IPv4 - subject alternative name field; see the note at the end of this description.
DNS - subject alternative name field
E-mail - subject alternative name field
Subject Name - subject name (maximum 255 ASCII characters, including spaces)
Note: If Peer ID Type is IPv4, please read the rest of this section.
If you type 0.0.0.0, the UAG uses the IP address specified in the Secure Gateway
Address field. This is not recommended in the following situations:
•
•
In these situations, use a different IP address, or use a different Peer ID Type.
Phase 1 Settings
SA Life Time Type the maximum number of seconds the IKE SA can last. When this time has passed,
(Seconds)
the UAG and remote IPSec router have to update the encryption and authentication
keys and re-negotiate the IKE SA. This does not affect any existing IPSec SAs, however.
Negotiation Select the negotiation mode to use to negotiate the IKE SA. Choices are
Mode
Main - this encrypts the UAG's and remote IPSec router's identities but takes more
time to establish the IKE SA
Aggressive - this is faster but does not encrypt the identities
The UAG and the remote IPSec router must use the same negotiation mode.
Proposal Use this section to manage the encryption algorithm and authentication algorithm pairs
the UAG accepts from the remote IPSec router for negotiating the IKE SA.

Chapter 30 IPSec VPN
There is a NAT router between the UAG and remote IPSec router.
You want the remote IPSec router to be able to distinguish between IPSec SA
requests that come from IPSec routers with dynamic WAN IP addresses.
