Disconnection issues

[RAIST]

depends on the implementation of the NAT server (generating additional Public IP's that direct to specific internal IP's and such are not typically used in the home). NAT in a standard home router has the most simple implementation of NAT, and can't really be turned off (you can disable extra features bound to NAT, but it is still performing translations if you are using it to give out IP's different than the WAN IP).

Basically, what they are saying is to strip your network to it's minimal components, like bypassing your device that is performing NAT (ie: not going through your router and connecting directly to your cable/DSL modem, as that is usually set up as a direct pass-through unless you have leased additional IP's). This restricts any translation to it's most minimal usage (basically, you are efectively DMZ'ed and all inbound traffic is going to that one system, regardless, as it is the only endpoint available).
