This topology has served me well so far through NAT / PAT so I will stick with it! Now PAT also known as Port Address Overload allows private IP addresses of inside hosts on your network to be translated to a single routable address with a random port number, so that a single address can … Continue reading Port Address Translation (PAT) explained, easy configuration, brief NVI0 mention, and thats it for the video series!
Once again I will be using R2 as our Dynamic NAT router for the Ethernet network, and the fundamentals of it are really just that it operates exactly like Static NAT, except we configure a pool of outside or "global" addresses that the inside "local" addresses can dynamically get used as needed. Now for the … Continue reading Dynamic NAT (DNAT) configuration, explanations along the way, verification commands, and important info for exam day!
I will use the IP SLA Track lab Topology to use SW1 as a host to perform the NAT on R2, however I have given the Ethernet segment a sub-network makeover! So to preface this I thought it was a good idea just to throw up the RFC 1918 IP address ranges, as they are … Continue reading RFC 1918 Range refresher, NAT Terminology, Static NAT fundamentals, configuration, and demo of SNAT in use!
