One client on WAN2 with Dynamic DNS. How ?

[Swiety]

Hello,
I have 2 WANs and I want to put all the traffic of one client on the second WAN (WAN2) but this wan has dynamic IP and i need dynamic DNS to be sent on this WAN2 because there is a server on this client`s IP.

Is it possible ? How to do that ?

Does your Dynamic DNS provider allow you specify ip in update script?

I dont think so, at least i cant find such a function. But how will it help ? I have dynamic IP :> so i cant put it on the dns provider.
