VPN connection disconnected by communication device
I am attempting to set up a VPN using OS X Server 5.2. I have configured my Shaw Router (Cisco DPC3825 DOCSIS 3.0 Data Gateway) as follows:
In the Server settings for the Mac, I have the host name set to a DynDNS domain. The Internet section status confirms I have 1 service reachable at <DynDNS URL>. The Network Interfaces match the Mac LAN IP Address.
The VPN Service confirms that Status is reachable. I saved the Config Profile and emailed it to my iCloud mail account.
I open the email on my iPhone SE and install the config file and a VPN Profile is created in the General Settings. I use the admin login uid (long version) and password of the server mac for the account information.
Everything in the set up seems to be configured correctly.
However, when i attempt to connect the iPhone to the VPN via LTE, I get the following message:
When I attempted to connect via WiFi, I get the following message:
The issue seems to coincide with the switch over to the iMac and an updated Shaw modem/WiFi Router. I did not have any problems when I was running Server for OS X 10.4 connected to an older Shaw Modem (no router). Unfortunately, that Mac in not working, and I don't have access to the previous cable modem.
I have spent hours trying to get the VPN working and have failed miserably. Since I did not have a problem with the previous hardware configuration, I think it is likely that the current hardware may be the issue.
Has anyone had success with this modem and version of server? And if so, can you advize on how to get VPN working?
Any help or advice would be greatly appreciated.
TIA
iMac, OS X El Capitan (10.11.6), Server 5.2
