The first isn't an issue -- the balance provider's default route is in
the 'balance' table.

The second is solved by upgrading to 5.0.14[.1]. The early IPv6 kernel
implementation of IPv6 did not support multi-nexthop routes so
Shorewall6 didn't either. Now that the kernel supports such routes,
that support has been added to Shorewall6.
