If both sides are continually sending Security Association, this may indicate port 500 traffic isn’t being received at the client Port forwarding isn’t configured on the MX for port 500Ĭlient isn’t trying to connect from behind the same MXĬlient public IP doesn’t match any non-Meraki VPN peer IPs or another currently connected VPN clientĪny extra configuration options manually applied to the MX that would override default client VPN settings

The destination IP and MAC addresses (or VIP for warm spare) are correct If the MX doesn’t respond to the client, verify: Phase 1 uses UDP 500, phase 2 uses UDP 500 or UDP 4500 (NAT-T)

The initiator sends a Key Exchange and the responder sends a Key Exchange response. The initiator sends a Security Association and the responder sends a Security Association response. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PolicyAgent

For Windows Vista, 7, 8, 10, and 2008 server:.RegValue: AssumeUDPEncapsulationContextOnSendRule HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\IPSec This DWORD value allows Windows to establish security associations when both the VPN server and the Windows-based VPN client computer are behind NAT devices. If the Windows VPN client fails with Error 809 when trying to establish a VPN connection to an MX located behind a NAT, add the "AssumeUDPEncapsulationContextOnSendRule" DWORD value to the Windows registry. S olution: Modern Windows devices do not support L2TP/IPsec connections when the Windows computer or VPN server are located behind a NAT. If this error appears, the Event Log won't have any relevant logs, as the traffic doesn't reach the MX's WAN interface.

Test this by changing the preshared secret in dashboard and for the RADIUS client on the server to something simple, such as "Meraki." If the error disappears, verify the secret used is correct on both devices and simplify the password if needed.

Alternatively, this message can be caused when a mismatch of preshared secrets between a RADIUS server and MX results in bad encryption of the password.

Solution: If the MX is configured with an ISP DNS server, change this to a non-ISP public DNS server such as Google 8.8.8.8.

Incorrect DNS name resolution from the MX's upstream DNS server.

Solution: If using Active Directory authentication with Client VPN, make sure the AD server has a valid certificate for TLS. Solution: If using Meraki authentication, ensure that the user has been authorized to connect to the VPN. When using AD or RADIUS authentication, be sure to enter the username in a format that will be recognized by the server, including the domain if needed (ex. When using Meraki authentication, usernames should be in email format (ex. Solution: Confirm user credentials are correct. Change the Startup type to "Automatic." If this automatically reverts to "Disabled" or fails to start, it may be necessary to remove the third-party VPN software. Find the service named "IKE and AuthIP IPsec Keying Modules" and open it. This can be reenabled by navigating in Windows to Control Panel > Administrative Tools > Services.

Solution: This occurs most often when third-party VPN software has been installed and disables the IKEEXT service.

IKE and AuthIP IPsec keying modules disabled (Windows only).If traffic cannot reach the MX on these ports, the connection will time out and fail. Solution: Ensure UDP ports 500 (IKE) and 4500 (IPsec NAT-T) are being forwarded to the MX and not blocked. More information about setting the shared secret can be found in the links at the top of the page. It must match between the MX and the client. Solution: Ensure that the shared secret is configured correctly on the client machine. Incorrect secret key (preshared key in Windows).This issue may also result in no event log messages if the client's traffic doesn't successfully reach the MX's WAN interface.
