Hi everyone,

I am trying to configure a WCCP enviroment with SQUID 3.3.8(transparent mode) in Ubuntu 14.04 nevertheless I cant get it to work.  I have tested squid configuring proxy in pc's browser an everything is working fine nevetheless when I try to configure squid in transparent I have problems.  

 

I have read the following articles:

http://kb.fortinet.com/kb/viewContent.do?externalId=FD30096

https://forum.fortinet.com/tm.aspx?m=108892

 

This is the squid configuration: 

#http_access allow localnet http_access allow localhost # Squid normally listens to port 3128 http_port 3128 transparent # FortiGate interface of wccp wccp2_router 10.1.0.5 # wccp version 2 configuration for standard service HTTP on tcp port 80 (service 0) with authentication password 'fortinet' wccp2_service standard 0 password=fortinet # tunneling method GRE for forward traffic wccp2_forwarding_method 1 # tunneling method GRE for return traffic wccp2_return_method 1 # Assignemment method (default), only relevant if multiple caches used wccp2_assignment_method 1 # wccp weight (default) ,only relevant if multiple caches used wccp2_weight 10000 # which interface to use for WCCP (0.0.0.0 determines the interface from routing) wccp2_address 0.0.0.0

GRE Tunnel

wccp0: gre/ip  remote 10.1.0.5  local 10.1.0.8  dev eth0  ttl inherit

I have enable wccp in port1 to which the internal network and squid are connected.   Nevertheless when I test wccp, I do not have any cache server available.
