Hello All
I am trying to simulate a site to site vpn conection via one router to the other but i want to create a virtual internet in the middle to simulate that the tunnel is going through an ISP can anyone think of any thing.
Thanks

Router A 10.1.1.1/30 > Router B 10.1.1.2/30
Router B 10.1.1.5/30 > Router C 10.1.1.6/30 -

Once you've got that nailed, then add an 'ISP' router in the middle - after you're good with that then you could always add in NAT to make it more realistic
Bear in mind that in a real life NAT environment normally you exempt your crypo traffic from NAT using route-maps - the exam doesn't go that deep though, as long as you can set up/troubleshoot VPN's you'll be fine -

I would mess with access-lists though, maybe add a zone-based firewall in between one of your vpn endpoint routers and the "isp" router to get more practice with each configuration since they are both on the ccna:s.
