There are so many VPN posts I thought I’d just start fresh for my circumstance:
I usually set up an L2TP VPN on the sites I install and have never had any issues, but I’ve also always used a Mac.
Now that an associate is going to be using a PC, I’m finding the setup is not as straightforward.
On the first site the Dream Machine Pro is in the DMZ of a Comcast Router which needs to operate for the cable boxes to work (we’re seeing this condition regularly so this config is standard these days).
- I am still using the public IP even though the UDMP’s WAN is a private address from the Comcast Router.
- My iPhone (and my associate’s) and my Mac connect almost instantly and without issue.
- The Windows 10 PC comes back with this error: “The network connection between your computer and the VPN server could not be established because the remote server is not responding. This could be because on of the network devices (e.g., firewalls, NAT, routers, etc) between your computer and the remote server is not configured to allow VPN connections. Please contact your Administrator or your service provider to determine which device might be the problem.”
I’m hoping the fact that the Mac has no issue helps to narrow down the problem somewhat. I appreciate any help/input on the matter!
