.SYNOPSIS
|
|
Designed to set a Windows host to connect to the httptester container running
|
|
on the Ansible host. This will setup the Windows host file and forward the
|
|
local ports to use this connection. This will continue to run in the background
|
|
until the script is deleted.
|
|
|
|
Run this with SSH with the -R arguments to foward ports 8080 and 8443 to the
|
|
httptester container.
|
|
|
|
.PARAMETER Hosts
|
|
A list of hostnames, delimited by '|', to add to the Windows hosts file for the
|
|
httptester container, e.g. 'ansible.host.com|secondary.host.test'.

Create the byte values that configures a rule in the PMapper configuration

|
The hostname or IP to map the traffic to.
