GNS3 Talks: Building large scale GNS3 networks (Part 4). DHCP Server, Router on a stick, SMB Part 2

This is part of my series "Building insane (large scale) GNS3 networks". I plan to continue adding more and more devices to the topology until..... well.... until I am done.
I continue building the GNS3 the topology by configuring a router on a stick, creating multiple DHCP pools - thus making the Cisco router a DHCP server. I also configure NAT (well actually PAT) on the Cisco router and test network connectivity.
