Router: Dlink: DIR-300

2-3 are for Eisregens Computer. He can host, both Aoc and EEC.
4-8 are for my Computer. I cant host.

With the old router, we used to be able to host, and join each others games. With this router I can still join, but not host.

Did I opened anything wrong, or is there more I have to do?
Btw, I checked in lobby and ingame the network adapter setting, the right adapter is selected.

Thanks in advance,

I can host, if I simple change the ip from eis slots to mine.
However, obviously he cant host then.
Is there any way so that we can both host at the same time?

No.

You can't forward the same ports to different computers!

With the old router (was a netgear) it was possible that both of us could host. So there gotta be a workaround or something.

Is it possible to open all ports in general? And if so, what security risks would appear?

You could forward the EE ports to one computer and put the other in DMZ. Or if it lets you, you can outright disable the firewall, but not a lot of routers let you even do that.

If you aren't retarded, then I don't really think there's any real risk to being in DMZ/having firewall off. For an attacker to make use of the open ports, there has to be a malicious program that's running on your computer to send/receive any communication.
