Nice post, but I just can't get it to work.
ReplyDeleteI create the loopback ok.
If I give it a static address, I can connect a GNS router into a cloud and ping to the "Host to GNS" loopback from GNS.
I can also ping from windows to the GNS router.
But no matter what I do in terms of connection sharing, interface bridging and static routing on GNS & windows, I just can't get the GNS talking to my real router or the Internet.
I've followed you tutorial to the letter, several times over from scratch.
I've also followed other tutorials and played around a lot myself.
I also have a real Cisco router plugged into my Linksys.
That gets a DHCP address ok and can ping the physical LAN int on my PC, but not the "Host to GNS".
Even though they're all in the same subnet and I have static routes everywhere.
Very frustrating.
I get kinda sick of Dynamips & GNS.
I spend more time trying to get it working how I want than actually doing any Cisco stuff.
I guess I'll keep plugging away at it, but I think I'll be dusting off my real lab soon.
You shouldn't give a static IP to the Microssof Loopback Adapter. Windows will give him one by himself after you choice it in a SHARING tab.
ReplyDeleteGo to SHARING tab in the interface that currently connecting your PC to the internet. Not in the Microsoft Loopback.
After selecting "Allow other network users to connect through this computer`s internet connection" windows will give an IP to the interface that you will choice, in our case we will choice MSLoopback.
As I know WindowsXP and Windows7 will use different IP`s to bridge.
Your comment about spending more time in getting gns3/dynamips to work than doing the actual practise is right. Gns3/Dynamips have been out for a while but no one has actually sat down to produce a comprehensive HowTo documentation.
ReplyDeleteNetworking has become very complex over the past 10 years, I prefer to be a Cisco engineer rather than a jack-of-all trade. The point is, we are spending too much time in fine tuning gns/dynamps instead of practising the core Cisco skill needed in the real world.
how can I add the quemu host to my GNS3 topology?
ReplyDeleteMy suggestion is to avoid connecting it to the internet. Rather focus the lab on an internal web server or device to get reply's. Do disconnect it from the internet while doing the lab. Good luck !
ReplyDeleteSecurity issues does not discussed here , but may be you right :)
ReplyDeleteIt works for me. Thanks.
ReplyDeletePlease can some one give the detailed steps on how to Link GNS3 to Local LAN on windows XP.
ReplyDeleteSo that other PC's on that LAN must access Router's on GNS.
