RE: [squid-users] IPFilter + FreeBSD + WCCP

Hi Raphael,

I have a couple of Squid servers running on FreeBSD 4.7-RELEASE with GRE
support.

Hi,
I got it working on FreeBSD 4.6.2 with the help of the instructions on:
http://www.freebsd.org/cgi/query-pr.cgi?pr=i386/47813 and
http://www.geocrawler.com/archives/3/165/2002/10/0/10004885/

Try this:

1. download the gre.c and the wccp patch and apply them according to the FAQ
on http://www.squid-cache.org/Doc/FAQ/FAQ-17.html
2. Rebuild the Kernel with "options GRE"
3. Configure SQUID with --enable-ipf-transparent option
4. Edit the /etc/rc.conf to enable ipnat:
    ipnat_enable="YES"
    ipnat_program="/sbin/ipnat"
    ipnat_rules="/etc/ipnat.rules"
    ipnat_flags=""

5. creat /etc/ipnat.rules with:
rdr fxp0 0.0.0.0/0 port 80 -> 208.224.179.254 port 3128 tcp (3128 can be
changed to your appropriate port)

6. Enable wccp on your router

7. run ipnat -l to see redirections

Good luck
Ralph

NB:
I did not add the "pseudo-device gre". I must say that I have trouble trying
to get WCCP working on 5.0
