You could use RB-750 which is much cheaper than RB-450G to balance
that little traffic, or RB-750G if you want to have room for growth.
It works just fine... nth+conn-mark rules can provide very good
per-connection load-balancing, and the quirks of some sites/networks
that require to use fail-over instead of load-balancing are also
doable.
I really prefer building blocks instead of final products to do
loadbalancing stuff, as there will always be another thing that
doesn't mix up with it and you can always make it work.
For two uplinks, it would look like this:
0 chain=prerouting action=mark-routing new-routing-mark=RotaGrupoA
passthrough=no in-interface=LAN
connection-mark=ConexaoGrupoA
1 chain=prerouting action=mark-routing new-routing-mark=RotaGrupoB
passthrough=no in-interface=LAN
connection-mark=ConexaoGrupoB
2 chain=prerouting action=mark-connection new-connection-mark=ConexaoGrupoA
passthrough=yes in-interface=LAN nth=2,1
3 chain=prerouting action=mark-routing new-routing-mark=RotaGrupoA
passthrough=no in-interface=LAN
connection-mark=ConexaoGrupoA
4 chain=prerouting action=mark-connection new-connection-mark=ConexaoGrupoB
passthrough=yes in-interface=LAN
5 chain=prerouting action=mark-routing new-routing-mark=RotaGrupoB
passthrough=no in-interface=LAN
(and then two default routes, each one tiead to one of the routing marks)
Four uplinks require more chains with nth=4,1 then nth=3,1, then
nth=2,1 and then the last uplink. You will also need the "no
load-balance" rules prior to this rule group doing some form of
fail-over.
