HTTP Explicit Proxy - V11.5+

Problem this snippet solves:

This iApp configures an Explicit Proxy using the new "Explicit" Proxy Mode that was introduced into the HTTP Profile in BIG-IP 11.5.

You only need LTM or APM provisioned.

It creates all configuration components required including:

  • DNS Resolvers
  • TCP Tunnel
  • HTTP Profile (Explicit)
  • Default Connect Handling set to Allow
  • SNAT Pools (Optional)
  • SNAT Default is Automap

If you require the Explicit Proxy to listen on more than 1 port e.g 3128 and 8080, simply just create another Application Service.

    Thanks for sharing this, how best could we filter URL's, have a whitelist of permitted sites and block all others?

    Brett, does this support proxy auth. I'm doing some testing and I would like to use my Virtual F5 as a forwarding proxy with Auth. The auth can be a single username/pass. is it possible to get this added to it?

    Eric, we are also interested in implementing some sort of user authentication.

     

    Did you had success with your Auth?

    Hi Eric,

     

    It supports Auth on the Client side. It doesn't support Proxy Chaining - this feature is due to release in BIG-IP 13.0

    Great iApp!! Works like a charm for HTTP and HTTPS :) Can this somehow be adapted to FTP(S), SFTP and SOCKS?

     

    Cheers

    Great work! I managed to deploy successfully explicit proxy for HTTP/HTTPS calls.

     

    Brett, is there a way to control server side encryption separate from the client side without using SSL Forward Proxy features? The problem I'm trying to solve is that I have dev machines supporting clear text only than need to reach resources on the internet that support tls1.2 only. dev machine >> (clear text) >> vIP (LTM Explicit Proxy) >> (encrypted - TLS1.2) Internet Resources

     

    I've tried different ways of using server/client ssl profiles without success. Before going with "tunnel" vIP and SSL Forward Proxy I wanted to see if there is any other way around as from what I read this solution would require additional license.

    This was working before but now, it just stopped working. The proxy no longer responds to requests
