Fortigate behind ISP modem

Hi all :) We have a fortigate 60C box, we intend to create a site to site VPN between our site and one of our clients' site. this fortigate box is behind an ADSL modem, so it' s wan interface is configured with a private IP address. to create the tunnel, we need to forward the IPsec trafic from the modem to the fortigate, which ports do we have to forward? Thanks all

Hello, It would be best to place your ISP modem into ' bridge mode' That will allow the fgt to get the external IP

Is it possible to do it with just port forwarding? because I don' t think the modem I have supports bridging.
