Anyone know a way of dynamically utilizing two default routes(gateways 
to the internet) on a NetBSD box without the use of BGP or some other 
dynamic routing protocol.  What I'm looking to do is load balance (just 
a simple 50/50 algorithm is fine) and be fault tolerant (use only 1 when 
the other is down).

I'm running a small office network, and we happen to have two different 
ethernet connections to the internet from different providers.  The 
NetBSD box is acting as a firewall/NAT router.  Not running routed or gated.

Thanks in advance,
Amir
