Far Cry 4 - Co-Op Problems?

[cluelessgenius]

we already tried turning off firewalls, forwarding ports and running as administrator.

 

if anyone got any suggestions id really apprechiate it right now.

so i figured it out and this is not gonna be good guys.

 

turns out this is not a far cry 4 problem.

far cry 4 like many other games requires you to forward specific ports.

i already knew this method since splinter cell conviction and blacklist do the same thing.

apperently in germany every knew customer gets an IPv6 address from his ISP and IPv6 doesnt support port forwarding.

so i had to upgrade to a business contract to get an IPv4 address from my ISP and now with forwareded ports it works perfectly.
