To select a proxy server:
 NAC 800 Home window>>System configuration>>Management server
1. Select Use a proxy server for Internet connections.
2. Enter the IP address of the server that will act as the proxy for Internet
connections in the Proxy server IP address text field.
3. Enter the port used for connecting to the proxy server in the Proxy server
port text field.
4. If your proxy server requires authentication, select the Proxy server is
authenticated check box.
a. Authentication method – Select the scheme used to authenticate
credentials on the proxy server. The following methods are
supported:
– Basic (not recommended) – The original and most compatible
authentication scheme for HTTP. Also the least secure because it
sends the user ID and password to the server unencrypted.
– Digest – Added in the HTTP 1.1 protocol, this scheme is signifi-
cantly more secure than basic authentication because it never
transfers the actual password across the network, but instead
uses it to encrypt a "nonce" value sent from the server.
– Negotiable – Using this scheme, the client and the proxy server
negotiate a scheme for authentication. Ultimately, either the basic
or digest scheme will be used.
b. Enter the ID of a user account on the proxy server in the User name
text box.
c. Enter the password of the user account specified in the User name text
box in the Password text box.
d. Re-enter the password.
5. Click ok.
