some of the clients can see the backend server (pool member) IP when they hit Virtual Server on their browser

Hi Folks,

 

We have a strange issue. We have a Virtual Server with Pool Members. When users enter the Virtual IP (running on F5 LTM) in the browser. They are getting a page but same time browser shows pool member IP (backend server) instead of VS IP.

 

I suspect that may be backend server (pool member) is doing rewrite etc. Please advise how to troubleshot this issue.

 

Thanks

    Hi!

     

    Since it sounds like your location has changed there must have been a redirect. If I'm not mistaken, ie. applications using .NET will automatically use the IIS binding configuration when using the build in functions for redirect.

     

    You could try to solve the issue by:

     

    1. Rewrite the application
    2. Use the HTTP profile option "Rewrite redirects"

    For more information about the redirect rewrites, check this page:

    From the article:

     

    "Choose All to rewrite all HTTP 301, 302, 303, 305, or 307 redirects to HTTPS, whether or not they match the virtual server."

     

    If you want all redirects to be re-written, that should do the trick.
