Ok.. I am sure I am just missing something easy here.
Basically, we now have 2 t1’s to the internet. The first one that has been in place is working fine. But now I have added the second to the mikrotik router. My problem is when I go to ping the ip address of the second t1 from a remote location, I do not get a response from it. Am I missing something here? I have never had two connections to the internet before and somehow I have a feeling I am missing something.
Thanks
Hi from Germany,
my english is not perfect, but i hope i can help you.
I have in the last weeks this problem. I have two SDSL Lines here with
2,3MBit (up/down) and static IPs.
Okay. I have found the solution 
But i work only with the Winbox-Tool 
First, you must go to “IP → Addresses” and add the static IPs to your
Network-Cards. I have 3 Lines on one Network-Card (with a Switch).
Okay, next step.
You must work with the “IP → Routes” Window. You found in this window
“Routes”, “Tables” and “Rules”. Please click on “Tables”. Look, you see,
one table with the name “main”. Okay, add 2 newTables with the
name “Line1” and then “Line2”.
Just, click on “Routes”. Click on the Dropdownbox and you see “Line2”,
“Line1” and “main”. You can not delete or rename the “main”. The both
entrys “Line1” and “Line2” is empty, right?! Okay, you must put the
Gateways in the Table. In Table “Line1” for your first Gateway and in
Table “Line2” for the second Gateway. Example:
Destination 0.0.0.0/0 - Gateway: (yourGateway) - Distance: 1
and the Interface must the extern Interface (where is install the modem).
Then, put your (Privat-)Network in this Table. Example:
Destionation: 10.0.0.0/24 - Gateway 10.0.0.1 - Distance: 1 and the
Interface must the intern Interface (where is install your privat network).
You have it?! Fine. please repeat this steps for the second line.
The last step!!! You must set the Rules!!! Click in the window on “Rules”
I think you have only one a entry:
Src. Address: 0.0.0.0/0 - Dst. Address: 0.0.0.0/0 - Table: main
This entry says: all incoming traffic and all outgoing Traffic use the table
“main”. But, we have two new Tables “Line1” and “Line2”. Add four(!)
entrys (or more what you need)
Example:
Src. Address: 10.0.0.0/24 - Dst. Address: 0.0.0.0/0 - Table: Line1
and
Src. Address: 0.0.0.0/24 - Dst. Address: 10.0.0.0/24 - Table: Line1
You see?! All incoming and outgoing Traffic over 10.0.0.0/24-Net must
use the Table Line1
I hope this little help can you help and have not forget a step.
My English is very bad, sorry, but i have work three weeks with my
problem and i’m happy to found self the solution. My two lines
functions very wonderful with mikroTik Router. Is very very good
