I am in the process of migrating our internet over to AT&T's MPLS network with a managed firewall & router. The selling point was the managed Firewall and the ability to grow and expand while maintaining a cloud based network. Since we are a fast growing company, this seemed like a great product. However, the problem I am encountering is the fact that we poll 100 different locations hourly for data files. With about 50% of these sites, I hit the external IP address, and they have port forwarding that allows me to ping their internal network and retrieve the data I need. Unfortunately, 50% of the locations have given me VPN access into their network with an IKE protocol, and I collect the data off of the internal IP address. Of those 50%, they are not wanting us to change the way that we can access their network, e.g. change to SSL connection, allow port forwarding to their firewall, ect. The AT&T Firewall will not allow me to configure the connection on their firewall, nor will they do it for me (AT&T has been a nightmare...stay away from this product!!). So, my next solution is to create a VPN connection on my system that houses the Polling Software (Windows 7), and connect to the sites that way. The thing is... I got with the companies BEFORE I made the agreement to change, and they "did not see it as a problem" before. Well, now they do not have the time to make the change or assist in any way.
So, this brings me to my question. Does anyone have a suggestion of software that I can use to set up the VPN connection using the IKE protocol? If so, then how will I route it, or will the AT&T router pick up on that VPN and just forward that connection to the sites for polling?
