Maybe a few words to the parent proxys: 192.168.1.1 and 192.168.2.1 are the ips of the Firewall, second one is a backup ip 192.168.3.1 and 192.168.4.1 are parent Proxys for accessing apps inside the corporate Network which cannot be accessed "DIRECT", only by internal proxy Regards Marcel --------------------------- http_port 8080 icp_port 0 check_hostnames off ssl_unclean_shutdown on dns_nameservers 192.168.50.2 cache_mgr support@xxxxxxxxxxxxxxxxxxx error_directory /usr/local/squid/share/errors/de-de logfile_rotate 7 # Logb�cher einschalten cache_access_log /var/log/squid/access.log cache_log /var/log/squid/cache.log cache_store_log /var/log/squid/store.log acl SSL_ports port 443 acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 # https acl Safe_ports port 70 # gopher acl Safe_ports port 210 # wais acl Safe_ports port 1025-65535 # unregistered ports acl Safe_ports port 280 # http-mgmt acl Safe_ports port 488 # gss-http acl Safe_ports port 591 # filemaker acl Safe_ports port 777 # multiling http acl CONNECT method CONNECT acl Bastion dstdomain 192.168.1.1 ### 2014-03-20 ### acl Bastion dstdomain 192.168.2.1 acl APPONE dstdomain app1.publicwebsite.de acl APPONE dstdomain APP2.publicwebsite.de acl APPONE dstdomain www.publicwebsite.de acl DEPT2 dstdomain www.dept2.corporate.net # Intranet DEPT2 ### ### 2015-11-05 ### acl APPTWOPROXY dstdomain 192.168.3.1 acl APPTWO dstdomain 192.168.100.3 # Verbindungen in die Firewall zum APPTWO-Server -
