SSL Offload for localhost driver

Hi,

 

We have a webapp on http and we publish it using https

 

So, client connect to BIG IP using 443 and the BIG IP connects to the app in port 80.

 

On my local computer, there is a pump connected in COM1 and a local driver.

 

The driver opens a local port 4444 on my PC and the connection is made using

 

When I go to the webapp through https and I try to use the pump from the webapp UI,

 

I get an error from the webapp saying that connection to the pump refused.

 

When I use only http, both from client to BIG IP and from BIG IP to the webapp

 

The pump is working fine from the webui of the webapp.

 

I don't see any errors in the ltm log, nor in the wireshark about SSL.

 

When using the https I don't see that my PC is trying to invoke

 

But when I use http all the way, I do see that my PC is invoking

 

Any idea how to solve this issue with BIG IP and using https?
