I have SuSE Enterprise 11 running as guest on my Win 7 host machine. I have a topology in GNS3 on my host WIN 7. My local host is 172.30.0.0/16 network. I'm able to ping from SuSE to the router in GNS3 within this network as my SuSE is also assigned an IP from 172.30.0.0 and the other way from GNS3 too.
However, I have another network 10.1.1.0/24 in GNS3 extended from the 172.16.0.0 network. I'm able to ping SuSE from this network from GNS3, but not able to ping back to this 10.1.1.0 network from SuSE.
I tried disabling the firewalls, but still cannot ping from SuSE to this network. Ping works only one way from GNS3 to SuSE.
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.
