You would need a way to detect link status and enable/disable the link in
shorewall accordingly.
Manually you can just run:
shorewall disable eth1
and when the connection returns
shorewall enable eth1
A better solution would be use something like lsm (read here
http://shorewall.net/MultiISP.html#lsm <http://shorewall.net/MultiISP.html#lsm>
and then download http://lsm.foobar.fi/)
