If the browser has a proxy configured, the destination address for any request is going to be the proxy server IP address. You'd need to look at the HTTP host header in the request to determine the actual HTTP server the request is being made to. If you configure a VIP on the port that the client is making the request to the proxy server, you add an HTTP profile to the VIP, check the Host header value and then make a decision on how to handle the traffic.

 

 

If you configure the pool for a port of 'any' then LTM won't translate the destination port from what the client requested when sending requests to the pool. If the client request worked without LTM, then the connection through LTM's VIP should work okay.

 

 

If you configure a new 0.0.0.0:8080 VIP with an HTTP profile and the rule which inspects the Host header, does it work? If not, what do you see on the client and the LTM log file?
