Um cliente tem um Sonicwall Pro 2040 executando o SonicOS 3.0 e gostaria de poder usar o cliente VPN L2TP de seus iPads para conectar-se a serviços internos (Citrix, etc.). Ativei o servidor L2TP VPN no Sonicwall, certifiquei-me de definir o AES-128 para a fase 2 e configurei a configuração em um iPad de teste com o nome de usuário, a senha e a chave pré-compartilhados apropriados. Quando tento me conectar, recebo algumas mensagens de erro enigmáticas no log no Sonicwall:

O log do console no iPad é assim:

Isso oferece alguma pista sobre o que está errado?
