Help With Fragrouter

Hello,

I am having some problems running fragrouter. I have 2 physical
machines with one of them running VMWare.

On the host running vmware I have two vmware images configured for
bridged networking. One running Windows and one running Linux. They
have the following IP addresses: Linux - 192.168.1.101, Windows -
192.168.1.102. The host OS IP is 192.168.1.51.

My other physical machine is running Windows and has the IP 192.168.1.50.

Now I am running fragrouter on the linux vmware image and I want to
fragment packets sent from the 192.168.1.50 machine to the
192.168.1.102 virtual machine. I add a route to 192.168.1.102 through
192.168.1.101 on my 192.168.1.50 machine with the following command
(route add 192.168.1.102 mask 255.255.255.255 192.168.1.101). With
fragrouter running in normal IP forwarding mode (-B1) I try to connect
from 192.168.1.50 to 192.168.1.102 using a web browser and I see the
connections show up in fragrouter display however I never get the
webpage back. Everything seems to be going very slowly.

Am I running this incorrectly or is it possible this is caused because
I am running the fragrouter machine and the target machine in VMWare?

Any suggestions?

Mike
