VPN site a site

O problema que estou enfrentando é o estabelecimento de uma VPN site a site entre o pfSense (versão 2.0.1) e o SonicWall Pro2040 Enhanced (versão do firmware: SonicOS Enhanced 4.2.1.4-7e). Toda a configuração foi feita corretamente, ainda assim recebi o seguinte erro no SonicWall -

"Falha no processamento da carga útil"

As fases 1 e 2 passam corretamente, mas problema com "processamento de carga útil". Descobri que poderia ser devido a incompatibilidade de chave compartilhada, mas verifiquei novamente, não há incompatibilidade com chave compartilhada em ambos os firewalls. Também mostra no SonicWall que o túnel está ativo

O log do pfSense está abaixo -
