3 Proxies and caching Common proxy settings HTTP Proxy Settings for the appliance when running as a proxy under HTTP This protocol is used for transferring web pages and other data (providing SSL-encryption for enhanced security). Enable HTTP proxy — When selected, the appliance runs as a proxy under the HTTP protocol HTTP Port Definition list — List of ports on the appliance that listen to client requests The following table describes the list entries. For information on maintaining a list of this type, see Inline lists. Table 3-9 HTTP Port Definition list Option Definition Listener address Local IP address of the appliance running as an HTTP proxy and port for listening to client requests Serve transparent When selected, the HTTP proxy processes also client requests sent in transparent mode requests Ports treated as SSL Ports on destination servers indicating to the HTTP proxy that requests with these numbers are SSL-secured Note: It can be necessary to specify these numbers when the appliance processes requests in transparent mode since there is then no CONNECT header to indicate a request is SSL-secured. Transparent common name handling for proxy requests McAfee Web Gateway uses passive FTP over HTTP connections Anonymous login for FTP over HTTP — User name for logging on as an anonymous user when requests are transmitted to an FTP server by the appliance running as an HTTP proxy Password for anonymous login for FTP over HTTP — Password for the above user name 54 McAfee Web Gateway 7.1.5 Product Guide When selected, the HTTP proxy does not use the destination IP address of a request to create a common name for the certificate it issues Instead, it copies the common name of the certificate that the destination server delivered. This might cause a problem if there is a common name mismatch in this certificate. When selected, the HTTP proxy uses connections in passive mode for transmitting requests to an FTP server Note: The passive mode might be required for the data connection (used under FTP in addition to the control connection). In some cases, an FTP server is not allowed to use the data connection in active mode, for example, when a firewall rule enforces this in a company network.

Proxies and caching Common proxy settings 3 FTP Proxy Settings for the appliance running as a proxy under FTP This protocol is used for transferring files, using separate connections for control functions and data transfer. Enable FTP proxy — When selected, the appliance runs as a proxy under the FTP protocol FTP Port Definition list — List of ports on the appliance that listen to client requests The following table describes the list entries. For information on maintaining a list of this type, see Inline lists. Table 3-10 FTP Port Definition List Option Definition Listener address Local IP address of the appliance running as an FTP proxy and port for listening to client requests Data port Port number sent with the source IP address of the FTP proxy when it opens a data connection to a client Port range for client Range of numbers for the ports on the FTP proxy that listen to client requests listener Port range for server Range of numbers for the ports on the FTP proxy that listen to responses from web servers listener Allow clients to use passive FTP connections McAfee Web Gateway uses passive FTP connections When selected, clients can send requests to the FTP proxy in passive mode, which is an option of the FTP protocol Note: The passive mode can be required for the data connection (used under FTP in addition to the control connection). In some cases, FTP clients are not allowed to use the data connection in active mode, for example, when a firewall rule has been implemented in a company network to enforce this. When selected, the FTP proxy uses connections in passive mode for transmitting requests to an FTP server Note: The passive mode can be required for the data connection (used under FTP in addition to the control connection).
