Configure RB750G - 2 WAN ports for Load Balancing Function

I have at the moment just one Provider and sometimes the connection drops and I really don’t like when it’s happening (as I have a Mail server and I need to have internet connection all the time), now I want to have a second Provider as a Backup, my question is: can RB750G be configured for my situation ?

I want the router to configured like this:

  • Fail-over and automatic load balancing for 2 WAN ports
  • Both WAN ports should be active at the same time and if one connections fails the other one should work fine

Thank you in advance.

Search the wiki, there are a lot of examples.
If you have NAT then best method is PCC
