Hi,

I'm using Shorewall and LSM to load-balance 3 ISPs. 
My configuration works, but when an ISP is disabled, LSM is unable to ping from 
the associated interface.

I understand why it happens : when `shorewall disable isp1` is called, 
Shorewall flushes the routing table isp1, and removes the nexthop in the 
balance table.
So when I want to ping 8.8.8.8 from eth1, no rule allows it.

I've STFW'd, but the only trick I found is to add a default route to eth1 in 
the default table.
The problem is, this only works with 1 ISP, as I can't add 3 default routes.

So what is the best way to manage this ?

Thanks for your attention.
