Req # 2 - Address/Port Binding NAT MUST maintain Address Binding and/or TCP Port Binding. Multiple TCP NAT Sessions could reuse the same TCP Port Binding. The filtering behavior of NAT for TCP sessions is as dictated by the NAT type (traditional, Bi-directional, Twice NAT types). Port parity, Port-contiguity - Some suggestions have been made to specifically mention about port-parity, port-contiguity not being applicable to TCP traffic. Needs discussion? |
