Acabei de configurar o tethering de iPhone do meu Snow Leopard Macbook Pro para o meu iPhone 3GS com o plano Datapro 4GB da AT & T. Ao tentar se conectar à minha VPN corporativa do MacBook Pro com o Cisco VPNClient 4.9.01 (0100), recebo as seguintes informações de log:

Não consigo encontrar nada on-line sobre isso. Eu encontrei uma única entrada para a mensagem de erro no Google, e era um sueco (ou algum outro site de idioma nórdico) que não tinha uma resposta para a pergunta.
Eu tentei conectar-me através de tethering USB e Bluetooth ao iPhone, e ambos retornam exatamente os mesmos resultados.
Eu não tenho controle direto sobre o firewall, mas se forem necessárias mudanças para que funcione, talvez consiga obter os poderes necessários para fazer ajustes. Uma solução que não requer reconfigurar o firewall seria muito melhor, claro ...
Alguém sabe o que posso fazer para que isso se comporte?
