Port Redirection

Hey Guys,

I have requirement where in client wants to have a setup like below:

In this case whenever any internal user wants to access application on port 22 we have to whitelist the destination address in AFM policy and there is a irule then which redirects the request to port 22

server on listening on port 22 <--------Internet <--------- F5 VS port 8822<--------- Internal Client wants to have SFTP 

when client_accepted {

                                   node [IP::remote_addr] 22

}

Now the requirement is whenever client wants to access the application suppose on port 8822 then the request will be redirected to port 8822 on the internet.

server listening on port 8822<--------Internet <--------- F5 VS port 8822<---------Internal client accessing app on 8822

what changes needs to be done in the same irule to cater this request, please suggest or if anyone have configured the same setup.

Note: My F5's are hosted in Azure Cloud.
