Cisco asa + squid + wccp

alexei-rus

Hi,
i used worked perfectly setup on CentOS:

iOS configuration for CiscoASA:
access-list wccp_redirect extended deny ip host $SQUID-IP any
access-list wccp_redirect extended permit tcp 192.168.1.0 255.255.255.0 any eq www
wccp web-cache redirect-list wccp_redirect password cisco
wccp interface inside web-cache redirect in

and add custom config to squid as:
wccp2_router $IP-OF-ROUTER
wccp2_forwarding_method gre
wccp2_return_method gre
wccp2_service standard 0 password=cisco

OS configuration for RedHat:
modprobe ip_gre
ip tunnel add wccp0 mode gre remote $ASA-EXT-IP local $SQUID-IP dev eth0
ifconfig wccp0 $SQUID-IP netmask 255.255.255.255 up
iptables -t nat -A PREROUTING -i wccp0 -p tcp –dport 80 -j REDIRECT --to-port 3129
iptables -t nat -A POSTROUTING -j MASQUERADE

now pfsense is also there with:
PfSense 2.3.2-RELEASE (amd64) built on Tue Jul 19 12:44:43 CDT 2016 FreeBSD 10.3-RELEASE-p5
Squid Version 3.5.19_1
i want to ask what things i need to do wccp with PfSense & cisco with SQUID method GRE wccp

how i create GRE tunnel from PfSense to CISCO from PfSerne.
what else i need to work on PfSense ?

could you tell me the configuration ?

Best regards.
