Hi,

i'm wanting to implement something similar to the solution described at http://wiki.mikrotik.com/wiki/PCC

I'd like to have the load-balance/fail using two different 3G wireless providers.

The view that i'm left with after reading the wiki page is that the two WAN links (WLAN1 and WLAN2) in the diagram have static IP addresses ... the problem that I have is that each 3G provider provides a dynamic IP address.

As such, I don't know which IP addresses to place in the configuration, since they change dynamically.

Is there a solution to achieve the above with my goals in mind?

thanks,

I think you dont. you can route to interface.

You will have to write a script which checks addresses assigned by ppp and updates firewall rules and routes with new values.
