Setting Up the Network Connection Server
The IAG Network Connector SSL VPN would be used for clients that you want to
have full network-level access to the corporate network from remote clients. Similar
to how LT2P and PPTP VPNs worked in the past but it will allow you to connect
from network locations that were not previously possible. Some of these environments
include connecting from a client that is behind a router using NAT or in environments
with highly restrictive fi rewalls. The Network Connector also allows you to specify
networking parameters including Domain Name System (DNS), WINS, Gateway, and
Domain Name for clients after they connect.
Another benefi t of the IAG Network Connector SSL VPN is that it supports IAG
Access Policies prior to connection. This allows you to confi rm compliance with important
security measures, such as Windows updates, antivirus, or other software applications
prior to the client being allowed to connect to the corporate network.
