Facility
Syslog facility:
WebGate sends notifications to syslog daemon for all important operations. You
can specify the facility for these messages. Default:
SyslogFacility user
The detail level of these messages depends on the settings for
LogLevel
.
EmailTo Email messages:
AntiVir WebGate is able to send emails with additional information (for example
about the relevant file), if it detects a virus or unwanted program. There is no
default value. In order to send emails, you must enter a recipient address. For
example,
EmailTo root@localhost
AddX
ForwardedFor
Header
Header analysis:
In case of a proxy chain network, a downstream proxy server can make no analysis
based on the Client’s IP address, because it sees all requests as coming from the
same address: from the proxy upstream. So the proxy knows only the address of its
direct communication partners’ and not the address of the computer issuing the
request.
If the
AddXForwardedForHeader
option is active, WebGate adds a header field
(X-Forwarded-For) to the HTTP request or adds the IP address of the Client it
received the request from. In this way WebGate can forward the Client IP address
to the downstream proxy servers. These are then able to analyze the header field
and to use the included indirect data for example, for access control mechanisms
or for logging purposes.
This option could also enable the use of ACLs for a Squid proxy, which is configured
by WebGate as parent proxy. The parent proxy must certainly hold the necessary
functionality for header analysis.
