Keith, first of all i thank you for the videos you post and hope you have the time to post more, especially on request. Please i have a problem which involves getting the ios image i need to use "gns3".

please i appreciate the the time and effort you put in posting to youtube.

@MegaDonaldification

Cisco licenses their IOS to customers who purchase their products. They haven't taken a "firm stand" on individuals who also use this IOS withing GNS3 for testing/practicing. I can't give away the IOS images, as I don't have the legal right to do that. If your company has an IOS router, I would start by talking to the IT people there and ask them for assistance.

Keith, I can't seem to get my persistent route to save. Otherwise, I can ping the "initial" router that connects to the cloud, but nothing behind it. Would you mind posting your working configuration with a static route created in windows, thus allowing full connectivity to your virtual environment? I'd appreciate it...

@cyberpsych1 Cool- Let's say we have the cloud connected to R1, with the pc using 10.0.0.2, and the router using 10.0.0.1 and the 23.0.0.0/24 network is on the other side of R1. On PC- route add 23.0.0.0 mask 255.255.255.0 10.0.0.1 -p route print (to see results) Make sure that routers behind R1 know how to route back to the 10.0.0.0 network, (to return packets to the PC). On all routers: router eigrp 1 no auto net 0.0.0.0 Best wishes, Keith

just FYI...if you dont see any option in GNS3 Cloud Configure window under NIO Ethernet...then follow the below solution:

Run GNS3 as Administrator which is right click your GNS3 file and click Run as administrator.

It will save you a big headache.

I had to restart my comp so the Loopback interface appears in GNS3!!!!!

What software are you using to generate the presentation with. I'm planning some presentations for work. I like the way the software you are using zooms in.

Hi Keith

Would it be possible to create more than 1xMicrosoft Loopback adapter if for example you wanted to create a GNS3 lab that incorporates your Host PC providing connectivity to the internet for both GNS3 & various virtual PC/Servers (Microsoft Virtual Server 2005/Virtual Box..etc)running for example Exchange Server 2007/2010 which is connected to GNS3 routers.(For the moment I'm using Qemu & Tinycore)

It is difficult to find info about Loopback adapters/connectors, WHY & HOW to use them.
