Packets are leaving FW2's internal interface, but no reply. I'm not the
dhcp crack, but in the dump I'm missing the Option 82 field. Should
there be the GIaddr?
If I start dhcrelay with "-a -m append" I can see the Option 82 field
with the value "vlan20", which is the internal interface name.
Is this correct behavior? Shouldn't there be an IP address?
