I have installed Vmware on Ubuntu Server and created multiple VMs and connect them to different VMnet adapters. Actually I created 30 VMnet on the server. So I have the physical network adapter in adition to all of those VM network adapters.
I connect my physical adapter to my laptop which has Windows7 and I share my wireless internet connection to my physical NIC which is connected to the p NIC on the server.
I installed GNS3 and add a router with 2 interfaces, the first one is bridged to the physical interface and it could get an IP address and connect to internet.
the second interface is configured with a different network.
I can ping both networks from into the router, and I could ping the first interface on the router that facing the internet from my laptop (Windows7) but I could not ping the ip configured on the second interface which is on a different network.
when I tried to ping both interfaces on the router from into Ubuntu server, there is no connection, how come and vice versa, although I disabled the firewall on Ubuntu. But I could ping windows (my laptop) IP address from into the router.
how can I make my GNS3 router ping to my bridged NIC ip address on Ubuntu server and vice versa?
