Hello, my friend and I have been trying to work ikemen out and I figured it was a good time to port forward. so I opened a port for Ikemen but for some reason when one of us tries hosting the other one still can't join.

We really don't want to install VPN programs for this as we feel it's quite unnecessary and I've recall a friend of mine playing against me directly without the need of having to use Hamachi/Tunngle/What have you.

We have one main concern as if we're port forwarding properly (creating NAT virtual servers and whatnot) and then what are you suppossed to put in the Netplay box (as far as I know the one hosting isn't suppossed to put any IP and just click OK)
