I'm finding that just a simple matter of my ppp session going down and
then back up again is messing up the delicate balance (no pun intended)
of route rules and tables that shorewall sets up to achieve
track/balance/policy routing.  If I simply do a "shorewall[-lite]
restore" things return to normal.

I'm not quite sure what's happening yet but it's probably got to do with
having both a DHCP Internet connection and PPPoE connection and having
them stomping on each other's default routes (even though I have set
removed the replacedefaultroute option from the ppp configuration), but
it makes me wonder if it wouldn't be useful to separate out the code
from shorewall[-lite] that restores the routing configuration so that
one can call that without having to reload the whole firewall
configuration.

In the meanwhile I think I probably have to fiddle these connections up
and down a few times and watch what each are doing with the default
route(s).  It sees that at some point the default route through the DHCP
connection gets completely lost so that shorewall fails to reload
because it can't even figure out what the default route is through that
interface.

Thots?
