Equinix Connect Single-Homed Direct – Open ports

Hi guys,

With the 'Equinix Connect Single-Homed Direct (Provider Assigned IP)' service are there open ports?

I have a Fortgate Firewall connected with the internet facing port configured to the Equinix supplied IP Address and have no problem getting internet through it and using NAT for a couple of device clients behind firewall, but I can't open a SSL VPN connection to the Firewall router. 

Are all ports closed by default?

Thanks for your help,

Ed
