IPSec and Remote Forticlient VPN

Hi Guys,

I have a fortigate 200D device already configured with a Remote Access VPN using Forticlient and everything is working without issue. I want to also create a Site-Site vpn with our branch office which will also be IPsec.

I want to know if it's necessary to have a second public facing network connection to serve as the gateway for the new vpn tunnel. In other words, is it possible for two different VPN tunnels to work off of the same public interface on my fortigate unit? The same IP address would then be used for both the Remote clients accessing the unit, and for this end of the Site-Site tunnel.

Thanks in advance for your assistance
