NAT is the technique of rewriting addresses on a packet as it passes through a routing device. There are far reaching ramifications on network design and protocol compatibility wherever NAT is used. This chapter will introduce two types of NAT available under linux.
How NAT works step by step?
In its simplest form, dynamic NAT is a four-step configuration process:
- Step 1: Designate at least one NAT inside interface.
- Step 2: Designate at least on NAT outside interface.
- Step 3: Create a pool of Public IP Addresses.
- Step 4: Create an Access Control List (ACL) that will include the local hosts or network(s).
