Configures any ranges which should be considered 'internal' and hence ignored in X-Forwarded-For processing.
Can be set in: global.cfg
Defines IP address ranges for Funnelback system devices in the
X-Forwarded-For header as these are to be ignored
by Funnelback when applying access restrictions. The IP address ranges are specified in CIDR notation.
access_restriction.system_ip_ranges is not set and all IP addresses will be processed.
A request goes through a network device (188.8.131.52) and then a second network device (184.108.40.206) and
then to the final network device (220.127.116.11) before Funnelback.
X-Forwarded-For header that Funnelback sees will contain
client IP, 18.104.22.168, 22.214.171.124
Since we know all request go through the above network devices We would like to ignore the associated IP addresses (126.96.36.199 and 188.8.131.52), when access restrictions are applied on the client IP address, we thus set
