Currently, I'm trying to establish a connection between two VPN's however the DSL providers are not able to assign a permanent IP address without pay an additional fee... I'm wondering if it's possible to connect two routers-firewall-vpn using a mac address? any idea? all the products that I found only use IP address...

Mac addresses will not work as they are not routable.  You will need static IP addresses on both ends to maintain a stable VPN tunnel otherwise when one end or the other eventually get assigned a new IP address by the ISP, the tunnel will break.

The Cisco PIX, for example, allows you to create a VPN with one dynamic IP but if both are dynamic then it wouldn't work.  I can't imagine the fee is that much for a static and you may even find that the ISP says it is dynamic but actually keeps giving you the same one every time.
I agree with dons6718 that both on static would be best.

Using 1 dynamic and 1 static IP address it's possible to establish a permanent VPN connection and would be able to reconnect the VPN if dynamic IP change? are you able to explain to me more about it?

It works by having the dynamic peer always create the connection.  The static just accepts it.   I have only seen it on a PIX as thats generally what I work with.
