Since long time I'm trying to upgrade from Squid 2.7 to 3.x but every try has failed up to now. I use a ZyXel USG 20 firewall with LAN and DMZ Zone. The Squid proxy server (MySquid) is running inside the DMZ with a single IP. The Zyxel USG 20 has a option for a "HTTP Redirect". This is defined like: Forward all HTTP Request from LAN to WAN to MySquid Port 3128. On MySquid, a Squid 2.7 stable version is running with this setting: http_port 3128 transparent It works fine - any HTTP requests from LAN goes through the MySquid Proxy. When I upgrade from 2.7 to 3.3 with some small modifications to the default configuration from Squid 3.3: ACL settings like before http_Port 3128 intercept I always get a "null size" / Bad Gateway 502 message in any browser inside the LAN for all HTTP internet pages. If I change the setting to: http_port 3128 (without intercept) and use a manual browser proxy settings (MySquid:3128) - the access works through the new proxy server like before. But that is no option - I can't and will not define manual proxy settings for any client in the LAN :( I can post more detailed informations - debug logs, settings files - just ask what you need Thanks, Martin _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
