IP Forwarding question

Hi,

 

 

Do you just need to have destination IP and port translation performed? Or do you need to rewrite the Host header value based on which server receives the HTTP request?

 

 

For the former, LTM will do this by default as long as you enable address and port translation on the virtual server properties. This is enabled by default for a standard TCP virtual server.

 

 

For the latter, you can use an iRule like this:

If you're running v10, you should update the above codeshare example to use the class command instead of the findclass command:

I don't think I need to re-write a header at all. I just need the virtual to forward them to the physical.

So you can configure a standard TCP virtual server pointing to a pool of servers defined on their IP and port 8888. LTM will translate the IP and port when it establishes a connection with the pool members. If you want LTM to parse the traffic as HTTP (for cookie persistence, inspecting/modifying layer 7 properties) you can add an HTTP profile.

That did it. Thanks!
