We are trying to connect to a server via VPN. The owners of the server, for our testing purposes, has the firewall open for all IP addresses.
On our network, our firewall allows outgoing VPN on two servers. On one server (the older server, Winows Server 2003), the connection is successful. On the new server (Windows Server 2008), the connection is unsuccessful.
To troubleshoot, we tried connecting to the VPN through personal laptops using personal hotspots.
I got on my laptop and connected to my AT&T hotspot to try to do a VPN connection. The connection was successful.
I then used a Verizon hotspot to try to do the same VPN connection and the connection was not successful!
I don't know if the laptop/hotspot issue has anything to do with the server issue, but still; this is very strange/confusing!
Any thoughts? This is a pretty high-priority issue, so any help would be great.
