windows-server-2012-r2

We have several services running on a cloud, they all are hosted on Windows Server 2012 R2, have public IP address and specific port.

Some of our customers can't reach them because for "some reason" the ports are cut between a firewall between them and us. (some customers are using a shared internet connection in a multi tenant office and they can't change firewall communication)

Well, you get it, we don't have the possibility to make all the firewall "allowing" the communication.

My customers all runs Windows 7 at least.

What is the best counter solution in such case, using Microsoft (Windows Server) technologies?

The best would be some kind of tunneling communication or VPN, but the customer should also be able to access his/her enterprise resources.

Bby the way, today we using IPSec using Windows Firewall to secure the communication, is IPSec tunneling a solution for us?

Otherwise, is there a service in Windows to enable some kind of VPN between a client and a server but only for a given set of servers?

Managed hosting firewall vs managing own firewall

I posted on stackoverflow as to the overall benefits of managed hosting vs non-managed hosting. The more I think about it, it seems to boil down to one question: should I use a managed host because they take care of the firewall, or would I be okay managing my own, software firewall?
