Hi Geeks!
I hope anyone could answer my questions, because I've allready invested several hours because of this problem.
The problem is, as the title says: The windows xp client can't reach the WebGUI from pfSense. The client can't also ping pfsense

The VirtualBox Configuration:
+ Windows XP Client
- One Bridged Adapter
with ip adress: 192.168.1.2 subnetmask 255.255.255.0
+ pfSense installed on harddrive
- Two bridged adapters
pcn0 LAN -> 192.168.1.1
pcn1 WAN -> 192.168.2.1
I've turned both firewalls off during troubleshooting, but it didn't fixed the problem..
Browsing to 192.168.1.1 doesnt work, and pinging the firewall won't work either.
When I change the client his IP address into 192.168.2.2, and if I ping the pfSense firewall after changing the ip I don't get the msg 'Time-Out' but 'Destination host unreachable'
PS: I also tried the internal adapters on both devices.
UPDATE: When I use the VirtualBox Host adapters on all devices -> I am able to ping between the host (laptop) and the client (virtual windows XP). But pfsense (virtual) won't respond
