In my previous installation for SuSE, which is deleted, I had give a route to any new subnet that I added in GNS3, with my physical router as the default gateway. Also the translated version of Cisco's default route command ip route 0.0.0.0 0.0.0.0 gateway
However, with this installation, even if I don't specify any route explicitly, I'm able to even access the Internet from the virtual machine.
But I do yes have specified route to 10.1.1.0 explicitly also.
I'm not really sure what I'm doing wrong. I'm new to SuSE and just am able to navigate around.
