BIG-IP APM SSL VPN - https traffic issues while using web proxy/URL filter

Greetings, my team is running BIG-IP APM for SSL VPN and we are experiencing intermittent issues with https/443 web traffic (no http/80 issues). We do have an "on premise" web proxy/URL filtering service. Our issues clear up whenever we put in a "bypass" on the web proxy for the VPN client address space.

 

Problem Behavior: For the first ~1 min 30 seconds or at random times throughout a VPN session, users experience web sites that load very slowly or that time out and do not load at all. The problem affects both PC and Mac and also happens in all browsers.

 

Has anyone come across similar issues with specific web proxy vendors? Does anyone have any tips, tricks, or best practices for getting the BIG-IP and web proxies to work well together??

 

Thank you Dev Central community!

    Hello,

     

    just for my understanding, you use APM VPN and you set on "Network Access" proxy pac or proxy in order to filter user, that's right.

     

    First if HTTPs don't work the first thing to check is your VS.

     

    • Can you confirm that you set a client server ssl (serverssl-insecure-compatible) in the VS that host your APM VPN Policy.

    And give me a feedback

     

    Regards
