 ## PIA Port Forwarding
 
-The PIA Port Forwarding service (a.k.a. PF) allows you run services on your own devices, and expose them to the internet by using the PIA VPN Network. The easiest way to set this up is by using a native PIA aplications. In case you require port forwarding on native clients, please follow this documentation in order to enable port forwarding for your VPN connection.

 This service can be used only AFTER establishing a VPN connection.
 
@@ -54,7 +54,7 @@ Here is a list of scripts you could find useful:
 
 To use port forwarding on the NextGen network, first of all establish a connection with your favorite protocol. After this, you will need to find the private IP of the gateway you are connected to. In case you are WireGuard, the gateway will be part of the JSON response you get from the server, as you can see in the [bash script](https://github.com/pia-foss/manual-connections/blob/master/wireguard_and_pf.sh#L119). In case you are using OpenVPN, you can find the gateway by checking the routing table with `ip route s t all`.
 
-After connecting and finding out what the gateway is, get your payload and your signature by calling `getSignature` via HTTPS on port 19999. You will have to add your token as a GET var to proove you actually have an active account.
