Sorry I searched Linksys RV120W, and didn't get results, this is why I asked.
But correct me if I am wrong, the RV120W is a single WAN router, not a dual WAN, so it can't help me.
Thank you Bruce, but as I mentioned above I didn't find anything because I put Linsys, when I put Cisco I found results.
Anyway, that device isn't a dual wan, so it doensn't help me.
A good link:
