Virtual Network on Fedora


Hi,

I have got a problem to configure the virtual network running on Fedora8. Pls someone here suggest me how to solve the problem...

-Two physical hosts (Window xp) and three virtual hosts (Fedora8)

-Virtual hosts connect on Ethernet adapter VMware Network Adapter VMnet8
NAT : 192.168.232.2/24

-on a physical host 192.168.0.4/24 , there are two virtual hosts 192.168.232.134, 135 /24
-on another physical host 192.168.0.3/24, there is one virtual host 192.168.232.128/24

-ping between physical hosts and their own virtual hosts --> ok
i.e @192.168.0.4, ping 192.168.232.134,135 , and vice versa is ok

-ping between two physical hosts (xp) -->ok

-ping between two virtual hosts (linux) on the same phy hosts -->ok

-ping from a virtual host (linux) to another phy host (xp) -->ok
i.e @192.168.232.134, ping 192.168.0.3 , and vice versa is ok

-but ping between virtual hosts on different physical hosts --> failed
i.e @192.168.232.134, ping 192.168.232.128 -->"Destination Host Unreachable"

-Adding other virtual host IPs in /etc/hosts doesn't help
-Disable firewall #service iptables stop
-No additional IP route

I do appreciate for any comment..ThX

You are using the VMware NAT interface, so it is going to act just like you put the VM's on different hosts behind a NAT router - they can't see each other. This is because VMware is doing address translation, making it appear that the IP address of the VM is actually the IP address of the host server. For VM's on the same host, VMware is knows the real addresses of each VM and can handle the routing. For VM's on different hosts, they true address of each VM is hidden behind the NAT translator and can't be found.

You either need to use Bridging or Host-Only with routing to the Host-Only subnet.

Regards,
