i uninstalled crysis 2 some days ago but i have one question left.

i always had this Internal firewall error which was saying iam Behind a Strct Firewall ... blah , NAT type was always set on strict..

i have opened my G data firwall for Crysis 2 and the firwall of the router was always turned off..

someone know how to fix this

and what i know Nat type should be always open, how to make it open , do i need to set ports in the router

BTW the same problem was on my laptop too but it was soved of hisself

Ps: excuse my own version of english .. i hope you understand what i mean

In your router, set PnP to ON (enable).

Since i know that you're from germany, i'll help you.

You've to go in your router and open this ports:
TCP: 64100, 6667, 29900, 2990, 28910
UDP: 27900, 27901, 64100

You have also to activate ''UPnP''.

With Fritzbox - ''http://fritz.box'' | Login with Password
With Easybox (Vodafone) - ''192.168.2.1'' or ''easy.box'' (Type this in browser adresse) | User: root + Password (123456)
With D-Link Router - Go into your router and go to ''advanced | DMZ –> Enabled and there you've to type in your IP adresse.''

in my router PnP alias plug and play.. is set on ON .

..like i say on my laptop The NAT type is Open in Crysis 2
but on my Desktop it Stays on Strict.. and thats annoying because that slows down my crysis game.. i really often loose connection or sometimes i cant join on servers with high ping aka non european servers

What router do you have?

stupid vodafone easybox crap .... lets see if i get this to work.. THX Ultimatecloaker

Log in yourself on easy.box-----> ''Daten''---->''NAT''---->''Spezielle Anwendung'' and then type in the ports with TCP and UDP.

Good luck.
