IPSEC Site to Site VPN Tunnel with one static IP address

Hi

I am very new to Mikrotik and would like to ask a question regarding site to site VPN’s.

At the moment we use Draytek routers at all of our site offices and we have recently installed a Mikrotik router at our head office.

Is it possible for IPSEC site to site VPN tunnels to be set up when only the head office has a static IP public address? All of our sites have dynamic public IP addresses.

I would be grateful for any help.

Kind Regards,

Steve
