Installation

Hello,
I've got a problem at the beginning with monowall.

I've 2 virtual machines and in one I mounted the monowall hdd. So I boot this vm and after this i can't make a ping to my other vm in "VMNet2", my virtual LAN. The other virtual PC is a Windows XP machine, the firewall is off and the IP is: 192.168.1.2/24. The IP from monowall is standard: 192.168.1.1/24?

What can I do???

Thanks for your help
