Here is what I want to do and really need setup by step on how to do it.

I want to route all internet traffic from mikrotik A ISP address 24.27.68.70 over and out of mikrotik B ISP address 65.15.120.120.

Any help would be greatly welcomed.

Establish a network between the two and add a default route (destination 0.0.0.0/0) on router A through the IP address router B has on the network between the two.

Ok I have done that but how do I tell the traffic to go out this route vs the route for the route for orginal ISP route? If I disable the orginal route I lose my pptp connection.
Thanks

So you do not in fact want all Internet traffic to go across the route towards router B?

Can you post a network diagram and DETAILED requirements?

If a computer connects to router B I want all of its internet traffic to be forwared over to router A and go out router A ISP.

I still want to be able to connect to router B over it wan address 65.15.120.120 for admin purposes.

I have attached a simple diagram.

Establish an EoIP tunnel between the two routers, use policy routing (see wiki) to route traffic across it.
