Description

Wireless: Log shows error message: Packet dropped by WLAN vpn traversal check

Resolution

Problem Definition:

Local WLAN client cannot access the remote VPN site network through a site to site VPN tunnel, and the following error message is displayed in the SonicWall log: "Packet dropped by WLAN vpn traversal check"

Resolution or Workaround:

If the "Require WiFiSec for Site-to-Site VPN Tunnel Traversal" option is enabled in the WLAN Zone > Wireless tab > WifiSec Enforcement section, then SonicWall appliance will not allow any wireless traffic to traverse through the VPN tunnel if the WLAN traffic is not protected by WifiSec security (i.e using GVC on all wireless clients).

Please Note: SonicOS Enhanced firmware 5.1.3.2 onwards the WifiSec Enforcement settings are not available on the WLAN Zone > Wireless tab, these settings are hidden and have to be enabled from the diag.html page (Eg: 192.168.168.168/diag.html).

For complete instructions refer KBID 6496: UTM: Wireless WifiSec Enforcement settings not visible in the WLAN Zone > Wireless tab

Tracking ID: <74674>
