I recently setup a wireguard and a openVPN VPN server in my Deco X55 router. I setup the VPN settings accordingly in the Deco App and my phone/tablet，and connected to the VPN server successfully (after checking the phone ip). 

I only need to access the internet from restricted country via the home VPN server，should I also set the port forwarding settings in the Deco App? or the Deco App already handle the VPN port forwarding automatically ? I am using DDNS of tplinkdns.com，and my phone already shown the gateway is the ddns external ip address.

Thanks :)
