VmWare and nat vmnet-interfaces

I need to simulate 5 ip networks from my computer. I have vmware and
have setup 5 virtual machines running Damn Small Linux. I have used
/usr/bin/vmware-config.pl and set up 5 nat net interfaces, but only
two of them shows. My ifconfig output looks like this:

eth1 Link encap:Ethernet HWaddr 00:12:F0:7D:ED:4C
inet addr:xxx.xxx.xxx.xxx Bcast:xxx.xxx.xxx.255 Mask:255.255.255.0

vmnet10 Link encap:Ethernet HWaddr 00:50:56:C0:00:0A

In addition to vmnet3 and vmnet10, I should have 3 more vmnet
interfaces. Is this a limitation in the vmware workstation or have I
done something wrong? All the interface configs in /etc/vmware look
similar.
