NAT

Traditional NAT would allow hosts within a private network to transparently

access hosts in the external network, in most cases. In a traditional NAT,

sessions are uni-directional, outbound from the private network. Sessions in the

opposite direction may be allowed on an exceptional basis using static address

maps for pre-selected hosts.
