I don't know how to do this.
I've 3 interfaces: WAN1, WAN2 and LAN.
With mangle and routing policy, I'm using voip over WAN2. WAN1 is default gateway for everything else.
What I need know (because bandwith balancing) is to let some l2tp users connect through WAN2 and the rest through WAN1.
My problem is that WAN2 seems that is not serving any Mikrotik service. No winbox, ping or the most important: l2tp.
I've tryed to mark connection incoming throung WAN2 and them mark routing but it's not working for this. I think this work for internal services (as Web server, terminal, etc.) but not for Mikrotik services.
