What VPN router are you using? &nbsp;This may be a basic question but I need to verify if you have created the CHAP authentication/account on both routers to accept connection from each other and ensure that you're using the correct credentials?

What VPN router are you using?  This may be a basic question but I need to verify if you have created the CHAP authentication/account on both routers to accept connection from each other and ensure that you're using the correct credentials?

The router is a Ubiquiti EdgeRouter Lite.<br />
<br />
There's a VPN section in the admin there - but I've left it alone because OSX Server has a VPN section in it and figured I'd go for that. &nbsp;What I've done on the router is opened up the firewall so that it accepts traffic on the relevant ports...and set up the port forwarding.<br />
<br />
Here's the config screen for that -<br />

I'm setting up a VPN at my work to route to OSX Server. &nbsp;I think that I've got the router/everything else properly configured - because when I attempt to login to the VPN I see results popping up in the logs.<br />
<br />
One thing I can't do, however, is log in. &nbsp;I keep getting authentication failures - and in the logs it says:<br />
<br />
CHAP peer authentication failed for &lt;username&gt;<br />
<br />
I've attempted using variations like username and domain\username format - to no avail. &nbsp;I was reading somewhere that the VPN user list is different than the normal user list? &nbsp;Any idea what might be happening?

OSX Server Users/VPN?

A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or travelling users access to a central organizational network securely. VPNs encapsulate data transfers using secure cryptographic methods and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.
