double natting with vmware


Hi,
I have a virtual machine in a natted interface vmnet2.
Ports are forwarded correctly into the virtual machine, but my host does not forward correctly the ports to the outside world.

for example, when checking if the port is open i sniffed on the phyisical interface and saw only the "syn" packet going to the virtual interface.
Inside the virtual interface i saw the same "syn" packet. the virtual machine replied with "syn, ack" and then it got a "rst" from my host.

what could go wrong? how come this "syn, ack" packet not going back to the physical interface?

thanks.

Yeah. Most likely iptables isn't set up correctly.
