Hallo all,
I replaced the web proxy from Barracuda to Sophos XG yesterday, I follow the solution of this link https://community.sophos.com/kb/en-us/123522, our network have different zone, the gateway for all zone is Cisco ASA firewall, the Sophos XG is in the zone DMZ as web and email proxy, I use the same IP and Port of old Proxy (Barracuda), because we don't want to change the Proxy configuration on every PC. now I meet a critical problem, the web performance is very slow after I replace web proxy from Barracuda to Sophos XG, in the past, the user can open a web page without any delay, but now the user have to wait 5-10 second to open a web page, I try to disable the IPS and WEB POLICY , but still same . when I use chrome, I can see the message on the bottom " waiting for proxy tunnel...." when the page is loading, I confirmed the auto search proxy is disable on browers . I made an another test, put the Barracuda web protection online again , then change the proxy server to Barracuda IP on PC's browers, user can open web page immediately. it seems that Sophos XG has problem , who can help me to solve this issue, I am really appreciate your help.
