Hello,
Apologies for the delay. To clarify, there was a known bug affecting L2TP over IPsec where the log message Out of IP addresses on tunnel [ID]! would appear, even with no active connections, preventing new clients from connecting. This issue was addressed and resolved with the 7.14.3 firmware release.
Could you please confirm whether the issue you described is now resolved after updating to 7.14.3? Installation instructions for upgrading from 7.14 are available here.
Let me know if there are still any issues with the L2TP over IPsec VPN.
Best regards,
