VMWare Fusion 6 Nat translation issue

Question

I have the following network diagram, using VMWare Fusion 6

I am able to ping from the en0 interface on my mac to all of the 172.16 network, and on the custom linux kernel (2.6.x) base I can ping the NAT server and the host side nic but I can't ping the 192 network. The Nat isn't translating to the 192 network. I thought maybe since 192 is a private network that it won't translate but it doesn't work with any network on the other side.

I also tried to put the VM on a host only network and add a route to the 192 network manually, and it still failed to work (VM to host).

Any help would be appreciated.

Answer 1

Verify a route exists on your linux box for 192.168.1.0/24:

netstat -rn

You'd be looking for something like:

Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.1.0     172.16.225.1    255.255.255.0   U     0      0        0 eth0
0.0.0.0         172.16.225.4     0.0.0.0         UG    0      0        0 eth0

If you don't have a route for 192.168.1.0/24 you can add it manually.

Example:

route add 192.168.1.0 subnet 255.255.255.0 gateway 172.16.225.1

This means any traffic headed for 192.168.1.0/24 from your linux box, would route to 172.16.225.1, and from there, 172.16.225.1 should route it the final destination

If you already have a route built for 192.168.1.0/24 then you need to check your firewall settings
