Well, I was wrong again. :^) Digging a bit further after posting this I
find that multiple "-to" entries ARE valid, and should do what you want.
The only reason I can think of (now) that all your traffic went to the
first on the list is that there simply wasn't any load to speak of. How
were you testing? Multiple simultaneous connections? Otherwise (from
my latest reading :^) it will simply keep sending traffic to the first
on the list, only using the next one if there is more traffic
'currently' (presumably based on the connection-tracking data) on the
first destination than on the second.
