If the connection doesn't come up after a few minutes, re-validate all configurations on both sides of the VPN connection.
If the tunnel is in an "Active" state, but traffic is not routing between your end user devices and servers, verify the following:
You have correctly configured an access policy for the hostname being accessed, such that you see the connection requests in Jamf Security Cloud: .
Verify that return routing is configured correctly in your environment. Depending on your network topology, you may need to create one or more static/dynamic routes, such that the traffic originating from the Jamf IPs are routed back to your firewall. An alternative solution would be to configure a Source NAT rule on your network appliance to map the Jamf IP network range to an IP already routable on your network.
