Several references to an appliance created by GNS3 team for accessing the internet but could not find the appliance internet.gns3a template under marketplace on GNS3 website (also tried to bridge my loopback adapter to my Wifi using a Cloud which failed), but did manage to get internet access using the NAT cloud option.

Tested with VPCS (ip dhcp) / Firefox (enable dhcp) to get an IP address, DNS etc… and could ping public IP addresses and also resolve names to IP addresses.

Tip: As NAT cloud only has one interface add a generic Ethernet Switch to it in the topology, this way it is possible to use multiple end devices.

Can also add a firewall such as pfSense between the generic Ethernet Switch and the NAT cloud.
