First NAT vs PAT
- What I described last week as NAT, is actually a specific subset of NAT known as PAT.
- NAT (Network Address Translation) is a 1 for 1 translation of Private Addresses for Public Addresses
- It Does Not Save you any IP Addresses
- PAT (Port Address Translation) is a Many to 1 translation of Private Addresses for Public Addresses
- It Does Save you any IP Addresses
