I’m new to the Peplink box and the community! I am running an OS X server behind my Balance 20 and am having trouble configuring my L2TP VPN. I am using NO-IP for DDNS service. I have configured port forwarding and inbound firewall rules for the three services that OS X requires for VPN access, but still cannot connect to the server. I had this running before when using my Airport Extreme as a router, but can’t seem to get it to go using my Peplink and feel like I am missing something small. Any suggestions welcome, and thanks for reading!
Turns out it was something small. I restarted the VPN service on the server and it works!
