Networking At DeVry
Posted by voice | Filed under Techie
For those who don’t know I am currently going to DeVry University for a Bachelors in Network and Communications Management, known within the college as the netcomm program. So recently me and friend decided to go into the college’s network lab, again shorthanded to netlab, to mess around with their switches and routers for a bit. Here are the results, click on images for bigger pics:
When we started…
What we ended with…
Essentially we configured a network that would give certian computers certian IP addresses via DHCP and then map them into the college’s network using NAT while using ACLs and VLANs.
Below are the configurations:
