STEP#4: Then simple add one NAT rule for local ip series and Action masquerade.
STEP#3: Then we should specify two default routes (destination 0.0.0.0/0) with appropriate routing marks and gateways.
STEP#2: Then We have to add two IP Firewall Mangle rules to mark the packets originated from user 1 and user2.
STEP#1: First we will create ADDRESS-LIST, and add our users in the list,.
To accomplish this task, the simple logic is … Now we will route users through DSL-1 OR DSL-2 wan links based on there ip addresses. Let us assume that we have 2 Users lists. You can take this idea and modify it according to your requirement, either use this logic and mix it with hotspot or pppoe base setup. I am just sharing basic logic on how i achieved it. I accomplished this task by adding 2nd DSL line with the Mikrotik BOX and few rules, and Alhamdolillah it worked fine :). He wanted to manage all users / link via single Mikrotik router-board. Recently at a local work setup gulzar-e-hijri, an OP asked told me that he wanted to add an extra DSL line just for some specific users (VIP users who are paying some extra money for better speed, as the current single dsl is getting clogged by over subscribed users.
