Hi, I have the mikrotik configured, and in my router active the DMZ to the mikrotik ip, and I have a pc connected to the out lan of my mikrotik, maked masquerade, etc, I can see web pages, and connect to emule, torrent etc, but with low id, if I want to connect to some p2p program I need to open the ports, but have any form to open all ports to the out local lan of the mikrotik?
You can use in-interface without port and forward all the port to any host. Futhermore you can define range of port like 0-65355.
Read the manual and you can see it clearly.
