I been running astaro since 2.0 i think, with the same hw, for some wierd reason i just did´t 2 of the nics working(dmz = 10.10.1.1,external = dhcp).
All i got from them where "down", did´t even work on dmz where i have static ip, so i just went back to beta 3.02 that works like a charm with that "homemade" dhcp.
