firehol-proxy - set up a transparent TCP, HTTP or squid proxy
transparent_proxy service port user rule-params
transparent_squid port user rule-params
The transparent_proxy
helper command sets up transparent
caching for TCP traffic.
The transparent_squid
helper command sets up the special
case for HTTP traffic with service implicitly set to 80.
Note
The proxy application must be running on the firewall host at port port with the credentials of the local user user (which may be a space-delimited list enclosed in quotes) serving requests appropriate to the TCP port service.
The rule-params define a set of rule parameters to define the traffic that is to be proxied. See firehol-params(5) for more details.
For traffic destined for the firewall host or passing through the
firewall, do not use the outface
parameter because the
rules are applied before the routing decision and so the outgoing
interface will not be known.
An empty user string (““) disables caching of
locally-generated traffic. Otherwise, traffic starting from the firewall
is captured, except that traffic generated by the local user(s)
user. The inface
, outface
and
src
rule-params are all ignored for
locally-generated traffic.
