Not sure what’s going on, but when I set up the loopback GNS3 works great. However, nothing else does. The PC can’t access the real internet. When I do a ping or traceroute, I see it trying to go out the loopback interface. Any ideas on how to fix that?

Hello all,

Problems with vista are down to windows firewall and the ACL settings in control pannel under user accounts (that crap popup thingy)…

Hashil,

Your problem is the windows firewall. Disable it and you should be able to communicate from the router to the PC.

Mijan,

Not sure. I haven’t used win2000 in a long time…

You might try the hacki forums.

Hi, I’m having problem integrating with win2000. I have used physical interface to bind with a virtual interface of the R1. But can’t ping the router from the host machine. Surprisingly, I can ping the router from any other device in the LAN, except the host win2000 machine.
Any idea please?

IFX,

You can go through the same steps to create several loopback interfaces.
