Route clients to a 5th & 6th DSL line using 2 RB750s?

Sun Mar 04, 2012 11:03 pm

We currently have 4 dsl lines, each line serves 8 clients.
we are marking clients per ip, so the mangle rule for client group 1 looks like this:
Code: Select all
  ;;; client group 1
     chain=prerouting action=mark-routing new-routing-mark=client-group-1 
     passthrough=no src-address=192.168.1.0/24
Then we route it out over the pppoe-out connection made over DSL 1
(DSL router is in Bridge Mode)

The Route looks like this:
Code: Select all
 dst-address=0.0.0.0/0 gateway=pppoe-out1
        gateway-status=pppoe-out1 reachable distance=1 scope=30 target-scope=10 
        routing-mark=client-group-1
OK, everything is working fine

Now, i have 8 more clients, i need to get another DSL line and route them over to that line.
I suppose i have to get another RB750, right. But how do i connect it together so that it can recognise the "routing mark" from the first router?
The PPPOE connection coming from the client will be accepted on ether1 of the 1st RB750, and client will be assigned ip address: 192.168.5.1 and marked as "client group 5" - but how will the second router recognise this and route it over to DSL 5?
Please have a look at my drawind.

Won't it be easier if you setup you DSL routers with NAT and DMZ to the MT, with a Switch in the middle, and then using Connection and Routing Marks in the Mangle table, choose through what DSL would be your client's traffic go ?

Something like :
Code: Select all

DSL1 (172.16.0.1/24) ------\
                           |
DSL2 (172.16.1.1/24)-------|                             172.16.0.2/24
                           |                             172.16.1.2/24
DSL3 (172.16.2.1/24)-------|                             172.16.2.2/24
                           | ----------> Switch -----------> RB750 <------ PPPoE Clients
DSL4 (172.16.3.1/24)-------|                             172.16.3.2/24
                           |                             172.16.4.2/24
DSL5 (172.16.4.1/24)-------|                             172.16.5.2/24
                           |
DSL6 (172.16.5.1/24)------/
Anyhow, I think that would be an option if you don't want to mount 2 RB750. I requires a little of work but I think its worth it.

currently i'm doing a pppoe-out to each of the WAN links (my DSL routers)
and i'm using the pppoe-out as the gateway.
do you have any example config that i would use for NAT-DMZ between the routers and mikrotik?
would the routers have to be i Router mode (ISP username nad pw programmed into the router) or will the mikrotik still be able to make the pppoe-out connection thru a specific DSL line?
also if its easier, i dont mind mounting two rb750s -

Buy a RB1100 or RB1200 so you have much interface.
I also think that rb750 couldn't run as reliable main router, pppoe concentrator and dsl load balancer

ok, i buy rb1100, then what do i do when i need to add a 11th and 12th DSL line? and what if i need to add 20 more dsl lines? how would i join the two RB1100 togeither?

looking at the pictures it seems you have adsl routers with pppoe clients that forward all traffic to the rb750 and between rb750 and routers you have a switch. If this is right you only need 2 port on rb: 1 for clients and 1 to the switch. I'll setup the routers on the same subnet (ex. 172.16.0.0/24).

not exactly
here are some more details
Code: Select all
