IP-Forwarding doesn't work!

[felfely]

Hello everybody.

I have a problem about IP-Forwarding.
I set the registry value of "IpEnableRouter" but IP-Forwarding does not work.
I tested it by vmware in this scenario:
I have a win7 Guest OS, win7 Host OS & a modem. I enabled registry value of "IpEnableRouter" in Host OS & set the default gateway of Guest OS to IP address of Host OS.
When I ping 4.2.2.4 in Guest OS, Requests don`t forwarding fron Host OS to the modem.

Can you help me?
Thanks a lot.
Ya Ali.

In the configuration for the guest, is it set to NAT or Bridged?

Please let us know ALL the IP addresses.

Is your modem using NAT or bridged?
If it is bridged, do you have multiple IP addresses from your ISP?
Because you can't use 4.x.x.x That is used by someone on the internet! Hence it will not route as you think it will.
You are only allowed to use non-routable IP address information HERE.

On the gues, you shouldn't need to change anything. The guest should build its routing tables once you give it the default router IP address.

Hello dear Shintaro,

I created a Lan between Host OS, Guest OS & modem.
modem ---> 192.168.1.1
Host OS ---> 192.168.1.51
Guest OS ---> 192.168.1.70

In this Lan, Guest OS forwards all packets destined to outside of the Lan to Host OS.
In step 2, Host OS forwards them to modem.

I know i can set 192.168.1.1 as default gateway of Guest OS but I need to route packets in this manner.
