Overview of implementation

30 Avaya VPNmanager Configuration Guide Release 3.7

Syslog

The security gateway has a syslog messaging facility for logging system error messages. The

message can be automatically sent to a destination running a Syslog server.

Client IP address pooling

Access control devices (ACD), such as firewalls, guard networks from unauthorized users.

Analyzing source addresses is one method ACDs use to decide which packets can enter a

network. The addresses that ISPs dynamically assign to VPNremote Client users is naturally

blocked because it is impossible to know ahead of time which address is assigned. You need to

configure the VPNremote Client IP address pools feature with the source IP addresses that can

be recognized by an ACD so that user access is not blocked.

SSL for Directory Server

As an added benefit, all communications with the directory server can be secured by SSL

(Secure Sockets Layer).

You can configure your VPN to run SSL at any time. However it is recommended that you

configure SSL before you put the VPN into service, so that the VPN services do not have to be

stopped.

Sequence to configure your VPN

The suggested order to set up your VPN is as follows. Refer to the chapters in this

VPNmanager Administrator’s Guide for details about how to create and configure these

features.
