It might be a good idea to use that to generate your configs rather than building them by hand. I believe that you need to mark your connections and use the marks to select the routing table, in addition to using the "from" rules that you posted. Otherwise, nothing binds the connection to a fixed route/interface in a load balanced configuration.
