MODEL: Archer C6, AC1200

HArdware Version: Acher C6 v2.0

Hello.

I just purchased the TP-Link router yestarday, and I went to ADVANCED>NAT Forwarding>Virtual Servers; to set up port forwarding, basically copied the port and internal IP from the previous router, but for some reason its not working as intended!

and as if things weren't bad enough now only 2 out of the 5 computers in the network get Internet access, and the WiFi is also not working anymore, I have no idea whats going on! They all had internet and WiFi access yesterday when I first set it up.

Is there some extra setting somewhere im missing for port forwarding on a PPPoE type conection?

any help is greatly apreciated!
