Hi,
I have ISP’s ADSL router in bridge mode on LAN1 on Mikrotik 951G-2HnD (routerboard v 3.18, OS 6.17).
I use PPPoE to connect on Internet from Mikrotik.
I wish to setup DMZ on WLAN adapter so I can use PS4 over it.
I’m ready to reset Mikrotik router on default and start from scrach.
Thank you in advance 
P.S. Any guidelines will do, just forward to right direction.
