MikroTik

I have 2 DSL connections and would like to use both on RB750. With the first one (192.168.1.1) I want to offer Internet service thought one ether port lets say ether3 and with the second one (192.168.3.1) to offer Internet service through another port ether4. Is this possible? I DO NOT want to Load Balance these 2 DSLs. Can anyone help please? I would appreciate it.!!

There are a variety of ways to achieve it. One simple way would be to use IP/Routes and create two VRFs. Place one DSL connection in each VRF along with the interfaces which should use that DSL interface for WAN access.

You will still need to do the usual things like masquerade each outbound WAN connection.

You could achieve the same effect in other ways too. Using VRFs you will then see two sets of routing entries in the routing table - distinguished by different routing marks.

1) One DSL connected ether1 sharing internet to ether2, and one DSL in ether3 sharing internet to ether4

1st NAT rule -> IN interface = ether1 OUT interface= ether2 action=masquerade
2nd NAT rule -> IN interface = ether3 OUT interface = ether4 action=masquerade

Both ether1 and ether3 must be properly configured (ip in the range and gateway) for their dsl connection.
ether2 and ether4 will be the gateway of your internal networks.


2) You have the 2 x Dsl módems/routers switched, both comes to the RB using ether1, for example.
1st NAT RULE -> SRC address 192.168.1.0/24 OUT interface=ether2 action=masquerade
2nd NAT RULE -> SRC address 192.168.3.0/24 OUT interface=ether4 action=masquerade


Hope this will work for you.

Yes, I'm using this configuration rigth now.
I have a configuration file attached to this thread: http://forum.mikrotik.com/viewtopic.php?f=13&t=61787

Thanks for the replies guys.. It sounds easy.. but since I am new to Mikrotik, is there a way to be a bit more explicit? Like some command lines via the Terminal window or a complete setup? I could do an "export" and send you my entire setup so you can understand what I am actually doing.
I want to mention that I am using the RB751G as a hotspot and distribute wifi internet access to about 40-60 users. I use Ubiquity NSM2 as wireless APs place on the roof of my house. What I want to achieve is, give Internet access to one AP from one DSL line and Internet access from the 2nd DSL line.
I use the built in radius and User manager that is provided by Mikrotik software (Version 5.17).

I really do not understand the VRFs and nats. But I think I can grasp things easily if explained in a more detail or better yet, given the entire setup.

I want to thank again, everyone on this forum that tried to help and the ones that will help..!!!

You could also just use two RB750's to achieve this and you get a more simple solution leading to more redundancy and security -- all for the low price of $39 (USD).

Thanks JJCinAZ,

I agree. That would be the easiest way to do it, but please keep in mind that I want to use it as a hotspot with the user manager built into the Mikrotik and want my users to be able to user the same user name and password no matter which antenna they are connected on. How could I do that?

Thanks a million for your prompt reply.

Go to: IP -> Firewall -> NAT tab

and you will understand what i told you.

Hello Pacoss,

Thanks for your help. I tried what you said about the Nat rules, but no success. I must be doing something wrong. Would you be able to help me better if
I send you the Export file? Please let me know and I will send it to your private e-mail if you want.

Thanks a million.
