Secure Computing SG300 User Manual page 258

The following field is displayed for SSL Tunnel Server only:
You may specify the Protocol to use when negotiating the SSL connection. Leave this
set to Raw when incoming connections are from a tunnel client. Setting Protocol to
another value allows the tunnel server to accept connections directly from an SSL client
other than a tunnel client, e.g. a mail client configured to use POP3 over SSL.
Tunnel client
A tunnel client accepts connections on Data Port from a host on the local network, and
forwards them over the Tunnel Port to the Tunnel Server.
Click Port Tunnels from the VPN section of the main menu. Select either HTTP Tunnel
Client or SSL Tunnel Client and click Add.
Enter a descriptive Name for this tunnel client. Check Enable.
In Data Port, enter the TCP port on which to listen for connections from local hosts to
forward across the tunnel. It is not necessary for this to match the tunnel server's Data
Port, but it often will.
Enter the publically accessible IP address of the remote Tunnel Server, and in Tunnel
Port, enter the TCP port on which the tunnel server is listening for connections. This
must match the tunnel server's Tunnel Port.
The following fields are displayed for HTTP Tunnel Client only:
If necessary, you may specify the Content Length to use in HTTP PUT requests. You
may also set Strict Content Length to force this Content Length for all requests.
You may specify a Maximum Age for connections, after which the connection is closed,
and a Keep Alive interval, the interval at which to send keep alive bytes to keep the
connection open.
You may disregard the remaining fields if you are not connecting to the HTTP tunnel
server via an HTTP Proxy Server.
Otherwise, either the Proxy Server IP address and the Proxy Port. If the proxy server
requires authentication, enter the details in Proxy User name and Proxy Password.
If the proxy accepts connects from clients with a specific User Agent field only, enter it in
Proxy User Agent.
