vmware with freebsd as a router

Hi-

I am trying to setup a lab in VMware.

I have 2 windows servers on VMnet2:
172.22.1.10
172.22.1.11

Another Windows server on VMnet3:
172.22.2.10

And a freebsd system setup for routing with 3 nic's:
192.168.0.196 - my home network
172.22.1.1 - on VMnet2
172.22.2.1 - on VMnet3

On the FreeBSD router I can ping:
172.22.1.10 - VMnet2
172.22.1.11 - VMnet2
192.168.0.1 - Bridged - Home network
74.125.226.5 - Google - Through Home network - Bridged

On the FreeBSD router I can NOT ping:
172.22.2.10 - VMnet2

On the VMnet2 Windows Servers I can ping:
172.22.1.1 - Freebsd Router  - VMnet2
172.22.2.1 - Freebsd Router  - VMnet3

On the VMnet2 Windows Servers I can NOT ping:
172.22.2.10 - Windows Server - VMnet3
192.168.0.1 - Bridged - Home network

On the VMnet3 Windows Server I can ping:
172.22.1.10 - Windows Server - VMnet2
172.22.1.11 - Windows Server - VMnet2
172.22.1.1 - Freebsd Router  - VMnet2
172.22.2.1 - Freebsd Router  - VMnet3

On the VMnet3 Windows Server I can NOT ping:
192.168.0.1 - Bridged - Home network

I think it has to do with my freebsd config (see below)

rc.cong--------------------------------------------------------------------------------------------------------------------

hostname="router"
#LAN 0
ifconfig_em0="inet 192.168.0.196 netmask 255.255.255.0"
sshd_enable="YES"

# Set dumpdev to "AUTO" to enable crash dumps, "NO" to disable
dumpdev="NO"


### LAN 1
ifconfig_em1="inet 172.22.1.1 netmask 255.255.255.0"

### LAN 2
ifconfig_em2="inet 172.22.2.1 netmask 255.255.255.0"

### Default Route
defaultrouter="192.168.0.1"

ipnat_enable="YES"

gateway_enable="YES"

ipnat.rules-----------------------------------------------------------------------------------------------------------
map tun0 172.22.0.0/16 -> 0.0.0.0/32 portmap tcp/udp 40000:65000
map tun0 172.22.0.0/16 -> 0.0.0.0/32

Am I missing something?

Thanks in advance
