I think I had similar problem when I tried to set up half bridge. I think t=
he
problem was dhclient script would not add a default route when IP address
changed. See the following patch:

You need to have a look at /sbin/dhclient-script and incorporate the change=
s in
that patch. I never managed to get my ADSL modem to work properly in half
bridge mode. DHCP server on my modem renews IP addresses every half a minute
and there was no way to change this setting. This would cause problems when=
 I
had large downloads, as the connection would stall when IP address was
renegotiated.
