If you’ve made it here, then at this point you should have a solid understanding of each of the four types of translation that can exist: Static NAT, Static PAT, Dynamic PAT, and Dynamic NAT.… Read More »NAT Terminology Disambiguation
Every type of NAT we have discussed so far have two things in common. The first is that only the source of the packet is used to make a NAT decision. The second is that… Read More »Policy NAT and Twice NAT
