Well, as i wrote above, Does NAT bear on link performance ? Since i keep getting a NAT strict advice on HALO reach and COD BAlck ops 2, im wondering how does nat bear on it and if there is a way to solve that. Reading some topics here i found solutions like opening ports, or set up DMZ but i've done that already. Whenever i make the test i get everything passed so its not expected to get this advice but im getting it. Thanks.
