Cisco NAT Terminology

Ed Harmoush — Wed, 15 Nov 2017 17:00:32 +0000

Cisco has created some NAT terminology which explicitly refer to the IP addresses and/or ports involved in Network Address Translation (NAT). While discussing the addresses involved in a NAT, using the terms like “Source” and “Destination” are common. However, using such terms can create some ambiguity. Specifically, the terms “Source” and “Destination” can create confusion… Read More »Cisco NAT Terminology

Routing Between VLANs & Layer 3 Switches

Ed Harmoush — Thu, 20 Oct 2016 15:37:46 +0000

We wrote an article which covers Virtual Local Area Networks (VLANs) as a concept, and another article on configuring VLANs on Cisco switches. The remaining subjects to cover are the different options that exist for routing between VLANs. This will let us illustrate the concepts of inter-vlan routing, Router on a Stick (RoaS), and Layer 3 Switches (occasionally… Read More »Routing Between VLANs & Layer 3 Switches
