Estoy intentando configurar una VPN de lan a lan entre un Cisco ASA 5510 (firmware 7.0(5), IP 222.222.222.222) y un firewall Watchguard X750e (firmware 10.2, IP 111.111.111.111).
Aparece la Fase 1, pero luego aparece el mensaje "IKE perdió contacto con el par remoto, eliminando la conexión" en los registros y el ASa nunca inicia la configuración de la Fase 2. ¿Qué podría estar causando esto?
A continuación se incluye información de registro y configuración, perdón por el muro de texto de aspecto feo:
De los registros al final de ASA:

Aquí hay un enlace a algunos consejos sobre discrepancias de IKE SA que pueden ayudar (también se cubren algunos comandos de depuración para ver):

¿Has intentado desactivar DPD? DPD entre diferentes proveedores puede funcionar más o menos... ¿Están ambos dispositivos configurados para usar el modo principal? Repase la configuración una y otra vez.

Tienes que dar un nombre DNS o una dirección IP a la IP de la puerta de enlace en la fase uno.
Ingrese la dirección IP y seleccione IP en el cuadro desplegable debajo de ella.
