Pfsense2 in VM (QEMU + 2 bridge Interface) DHCP on LAN assigns IP to WAN

[Nachtfalke]

Hi,

a friend of mine is using Ubuntu with 2 NICs in bridged mode. pfsense is running on this machine with QEMU as virtual machine with the 2 bridged NICs.

The pfsense WAN interface uses DHCP to get an IP address.
On the LAN interface pfsense runs a DHCP server.

If pfsense start the assigned IP on WAN is correct. If we disable the WAN interface and re-enable it, the new IP on the WAN interface is an IP of the address pool of the LAN interface !?!

DSL Router (DHCP-Server) –- 192.168.2.0/24 --- (WAN) pfsense (LAN/DHCP-Server) --- 128.0.0.0/16

Tried with this snapshot 2.0-BETA5 (i386) built on Tue Feb 1 19:36:32 EST 2011 and the two others before. Same problem. Not sure, if this is a pfsense problem with bridged interfaces or something else. In both cases a hint would be very helpfull.
