Добрый день!

Есть маршрутизатор Cisco ESR10008 который терминирует L2TP (без IPsec) туннели пользователей. Виндовые клиенты подключаются нормально, все работает (после отключения ipsec в реестре). Проблема заключается в роутерах D-Link DIR-300/320 коих у наших абонентов полно. Привожу конфиг и логи:
