Description
When using agent-based
testing, the endpoint must point
(using a browser window) to
destination port 88 on the ES for
testing, which is redirected to
destination port 89 (end-user
access screens) on the ES.
Domain Name Server (DNS).
When an endpoint is
quarantined in DHCP mode, it
uses the ES for its name server.
Any endpoint configured to use
an autoproxy (DHCP endpoint
enforcement mode only), and
when using agent-based testing
and static routes, the destination
port is 3128 (squid) on the ES.
These ports are opened by
default when File and Print
Sharing is enabled, but are not
used by Novell ZENworks
Network Access Control.
This port is first used for NMB
lookup (identify yourself) on
Windows endpoints. If this port
is not open, the endpoint cannot
be tested.
Then, this port is used for
testing endpoints with the
Agentless method.
NOTE: This port is opened by
default when File and Print
Sharing is enabled.
