“Hello World!’ - Hey so it’s been while since posting last and some things are getting back to normal since the move. One of them is my office Very happy about that! One thing that has not gotten back to normal is routine studying - I’m so far behind from my goal - but I do have 2 months before the year is out to complete the BSCI - Don’t know if I can do it though. I’m just not in the zone. Well anyway, here is a lab I’ve been meaning to put together to share with you all. It’s a lab involving NAT/PAT and Overload .. Sean shares this with us.

I setup this lab up to help me better understand ACLs (Standard, Extended, Dynamic, and Reflexive) and NAT’ing (e.g. Overload, Dynamic, and Static).

The IOS used is a 3640 version 12.4. The special topic about this lab is I did this on a Mac Book Pro and used the TAP/TUN drivers to attach my MBP into the simulation. So this config requires that GNS3 be run as root (e.g. sudo) in order to allow the TAP device to be created. Information on the TAP/TUN drivers for OS X can be found here:

Thanks for the lab dude! You too can share labs - You can either create a post here on the site with your lab and send all files necessary to the lab to postmy AT gns3-labs.com. You can also skip posting it and just send all files necessary to the lab to postmy AT gns3-labs.com. Thanks to all the help from contributors like Sean - you call help keep this site going!

Routers Used: 3640

IOS: c3640-ik9o3s-mz.124-25b

Feature of Topology: Static NAT, Dynamic NAT, Overload NAT, Network Address Translation (NAT), Port Address Translation (PAT), Access Control Lists
