Dss0 I send an invitation via the native friend list and simply accept it, but he gives me error "Impossible to connect to game session"

Hi everyone, I'm trying to create a private match in t5 zombies with two computers connected to the same LAN (that means same WAN IP address because of NAT), but if I host the other computer cannot connect to me and vice versa. Playing with friends with different connections works instead. I do not face this problem in other cods (t4 and t6). Is there any fix to this?
