Can't connect L2TP VPN

Mahir

Hi everyone, i have a atp 500 firewall. There is an L2TP configuration made by xyxel distributor.

Genarally i have no problem but some clients can not connect with l2tp.

I 've tried deactive client's firewall, network protection and antivirus program but this is not helped.

I can access to my local using l2tp with same account and different device?

Is there any configuration i can fix this issue on client's side.

Thank you for your help,

Mahir.

Hi @Mahir,

Follow the configuration guide to setup L2TP VPN on Windows/macOS/iOS. We suggest you download script files directly from ATP500 and run the script file on each device.
