Hi , I created a simple firewall for our office, actually is just
simplified from pfsense 2.0.1,
I simplified it in vmware, after we finished all the changes, we move it
into a actually hardware machine, and we met this problem,
actually , it is working in no vlan, but when traffic comes from vlan2, I
will met this issue, , and if I flush the ipfw rules, vlan2 also work!

We have managed to install a pfsense in to hardware machine, it is working
properly, So is it because mine was installed into a vmware first, so the
driver for it is different from the pfsense which directly installed on the
hardware machine? I am planning to install a pfsense in the vmware
tomorrow, and copy it into the hardware machine,
Thanks very much,
