My problem is that squid is not working with transparency. The browser
traffic goes directly to the Internet.


If u r doing with PF, Can I have your pf rules?

I am doing squid 2.7.9 tranparent with OpenBSd 4.8.


These are my PF rules.


# filter rules
block in log
pass out log


pass in log on $int_if proto tcp from $lan_net to any port { 80 8080 } \
rdr-to 127.0.0.1 port 3128


in squid.conf file

http_port 3128 transparent


acl localnet src 10.0.0.0/8 # RFC1918 possible internal network
acl localnet src 172.16.0.0/12 # RFC1918 possible internal network
acl localnet src 192.168.0.0/16 # RFC1918 possible internal network

http_access allow localnet


It's worth noting the whole intercept section underwent a code change to
make the NAT lookups run-time selected. At the time care was taken not
to change the lookup sequence, but even so mistakes were found. There
were also outstanding reports that some were badly broken before the
change (doing the lookups completely backward so "myip" ACL matched the
remote client).

I have not had anyone report either "works" or "fails" for IPFW,
IPFILTER or PF on the 3.1.10 or later releases.

I believe the other modules work due to people using them successfully.

FWIW; in theory you should be able to build Squid
with them all enabled and whichever your system provides will be used.

Thank you Amos.

Would you suggest that I revert to 3.0 or even 2.7?


For the immediate result I think you should use 2.7, check that the PF side of things is fine. When you have confirmed a PF setup with 2.7 as working, please try 3.1 again. I would like to know the result of that (good or bad are both useful) and if you are able to help debug any bad results to get 3.1 fixed that would be extra great.
