Hello Manami
So in more general terms, you want to be able to connect your GNS3 topology to the Internet, and have devices on that topology (a PC running as a VM in your computer) be able to view web sites. You can connect your topology using the following information provided by the GNS3 forum:
Now what your local topology is (MPLS VPN, simple IP network, or anything at all) doesn’t matter, you can still connect it to the Internet as shown in the above link.
I hope this has been helpful!
