Most likely a bug in either FreeBSD 6.4's if_re or Xen. Real-world RealTek controllers that use the
re(4) driver support hardware based VLAN tagging, and FreeBSD uses that feature if it's available.
Perhaps it's a problem in the interaction between FreeBSD and Xen? (e.g. FreeBSD thinks the virtual
NIC does "hardware" based VLAN tagging, when in fact it does not)

You could try disabling VLAN hardware tagging by entering the following commands on
<http://m0n0wall/exec.php>:

ifconfig re0 -vlanhwtag
ifconfig re1 -vlanhwtag

(only lasts until the next reboot)
