Sorry for any confusion in my explanation, I will try again.
We have a Apache web server that needs to send information to an external server. From what I am being told the encryption feature of this server is a resource hog so the F5 is needed for that task. The Apache server sends the information to the vip on the F5, the F5 encrypts the traffic and sends it to the pool member which is an external server. The issue I have is the node is defined by ip address 1.1.1.1 the external web server does not have a ptr record so reverse lookup will not work and connection fails. We are sending information to the external server there is no request nor is it a response. All traffic on this VIP will need to have the ip address changed to FQDN both values will stay the same.
Does this make sense?
