Source IP redirect, change host, uri and change to 443

 

I'm using BIG-IP LTM

 

I have a VIP on port 4001 taking external connections, this goes to a pool with a client SSL cert.

 

I am trying to "route" to a different destination based on the source IP address. However, I need to manipulate the uri as well.

 

I have tried this via an iRule, but looking at the forum people are saying just use the policies section of the F5.

 

I am a network engineer by trade and I very rarely get this deep into LTM. Please can you assist? I have outputs from what I have tried below.

 

I have run packet captures and see that the request does forward, but in plain text (iRule output), so I have tried to encrypt it before sending it to the destination, but I don't think I'm doing it right.

 

pool_RTS_Azure = dev.api.comany.com:443

pool_RTS_4001 is the default pool

pool_RTS is the same as pool_RTS_4001

    Hi phipse,

     

    If you want to re-encrypts traffic on the server side by initiating a new SSL connection between the F5 BIG-IP and the web server add a SSL profile (Server) on your Virtual Server, eg severssl.

    Despite this, all configuration seems OK.

     

    Regards

      Hi Lidev,

       

      This isn't working. With the iRule I can not change the host entry in the URI, it just forwards the request as it is to the pool. However, the policy does seem to work, but I receive an error back from the Azure server, like it's receiving a GET request rather than a POST.

       

      Thank you

        It depends on what you want to do with TLS/SSL trafic ?

         

        SSL Offloading (clientssl profile/no serverssl profile on virtual server) terminates SSL at the F5 and the server side traffic is non-encrypted.

        SSL Bridging (clientssl profile and serverssl profile on virtual server) terminates SSL at the F5 and then re-encrypts traffic to the server side.
