Hello, I'm having trouble to make Squid 3.5.23 work like Squid 3.1.20 does. Here is my setup: <clients> | <router> | <squid proxy> 10.0.0.Y/24 | 10.0.0.254/24 <-> 10.100.0.254/24 | 10.100.0.100/24 The goal was to have the <squid proxy> as a transparent HTTP proxy for all <clients>; it was achieved few years ago using Squid 3.1.20. - <clients> have one network interface and 10.0.0.254 as default gateway - <router> is: -- obviously forwarding packets, -- owning the ADSL, -- doing the transparent redirection of <clients> to <squid proxy> using NAT: -A PREROUTING -s 10.100.0.100 -i dmz -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT -A PREROUTING -s 10.0.0.Y/32 -p tcp -m state --state NEW -m tcp --dport 80 -j DNAT --to-destination 10.100.0.100:3128 - <squid proxy> have one network interface and 10.100.0.100 as default gateway. Squid's configuration is quite simple: http_access allow all http_port 0.0.0.0:3128 intercept cache_mgr ... cache_mem ... ... This is working perfectly fine with Squid 3.1.20. But now that I have upgraded <squid proxy> to 3.5.23 (from Debian Wheezy to Stretch) this is not working anymore. The test I'm using is simple: "curl http://www.google.fr -I" from <clients>. <clients> are getting 403 returned by <squid proxy> 3.5.23. In Squid's logs I had: "ERROR: No forward-proxy ports configured.". After reading Squid docs, forums, mailing, list, etc, I tried to add another http_port: http_access allow all http_port 0.0.0.0:3128 intercept http_port 0.0.0.0:8080 But it does not work either, Squid seems to loop internally with a lot a log access_log (even for one request only). I feel like I missed something obvious, I spent quite some time to understand but had no luck. Am I missing something ? When I was reading on the web, some users claimed that I should have two network interfaces between <router> and <squid proxy> ? If that true, why is it working perfectly with Squid 3.1.20 ? Any clue will be appreciated. Thanks. _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
