Enable ip forwarding in Windows 7 as VMware's guest in Linux box

[lib0]

The Linux box is connected to a LAN, the host traffic to the LAN goes through eth0. The default traffic for the host should go through the Windows 7 guest.

The Windows 7 guest has access to the LAN in bridged mode.

I tried to use VMnet1 (the local adapter from VMware) to route the default traffic from the host to the Internet through the guest.

For the Windows guest:

Adaptador ethernet VMware Network Adapter VMnet1:
Sufixo DNS específico da ligação. :

Endereço IPv6 de local de ligação : fe80::69ed:c173
Endereço IPv4 . . . . . . . . . . . . . . : 172.16.233.2
Máscara de sub-rede . . . . . . . : 255.255.255.0
Gateway predefinido . . . . . . . : 10.66.81.254


From the Windows 7 guest I can ping 173.16.233.1, the VMnet1 host interface, as both are in the same network.
I don’t have access to windows snap-ins, so have to use netsh commands.

The problem is that I still have no access from the host to the Internet through the Windows guest, and cannot ping the VMnet1 of the guest.

At the start of `ipconfig/all` the output shows Rota IP activada. . . . . . . . . : Não

Which is that ip routing is not activated, already I tried to activate it to VMnet1 interface in windows guest with:

netsh interface ipv4 set int "VMware Network Adapter VMnet1" forwarding=enabled

netsh interface ipv4 set int "VMware Network Adapter VMnet1" forwarding=enabled store=active

netsh interface ip set address name="VMware Network Adapter VMnet1" static 172.16.233.2 255.255.255.0 10.66.81.254"

How to proceed from here? Enable firewall for packet filtering? Add route from 172.16.233.2 to the guest gateway? How to do it?
