When connected to L2TP WAN GroupVPN, I am unable to manage the appliance. When I try, I receive the following message:
You do not have the administrative privilege required to login here.
Note that you are currently logged in to the DELL SonicWALL as a L2TP Client user and login here is only allowed for management of the appliance. Since you do not have the privilege for that, please re-connect using an account with administrative privilege.
Please contact your system administrator for further assistance.
I have made sure the LAN interface has HTTPS management enabled, and the WAN GroupVPN VPN Policy has HTTPS management enabled as well.
There is no firewall rule that is specifically blocking me, since I can access the page itself.
My user is a SonicWALL Administrators group member, and in that group, I have specifically added Firewalled Subnets and the X0-X6 management IP's to the group VPN access list.
The WAN interface HTTPS Management is fully disabled.
Model and firmwar: SonicWall TZ-215, SonicOS Enhanced 5.9.0.6-3o
Any ideas? Did I miss a permission?
Check your firewall Rule for VPN to LAN, I have also found that "Firewalled subnets" is not as good as configuring address groups manually.
Also ensure this is checked:
