Como temos tido alguns problemas com a perda esporádica de pacotes, estou preparando um roteador substituto (também um SSG5) para o nosso atual Juniper SSG5. Eu configurei o novo SSG5 de forma idêntica ao antigo.
Temos um intervalo / 29 IP com uma configuração IP única como um mapa MIP para um servidor e dois outros sendo usados para mapas VIP. Cada VIP / MIP é acompanhado por políticas relevantes.
Resumindo: tentamos conectar o novo SSG5 e algumas coisas não estavam funcionando como deveriam. Não tem problema, acabei de reconectar o antigo. No entanto, algumas coisas ainda estão quebradas, mesmo quando reconectei a antiga. Eu temo que eu tenha alterado inadvertidamente algumas configurações enquanto navegava pelas configurações antigas na minha tentativa de reconfigurar a nova unidade SSG5.
Todo o tráfego de entrada parece funcionar conforme o esperado. No entanto, o servidor 192.168.2.202 não pode iniciar conexões de saída. Ele funciona perfeitamente na rede local, mas qualquer pings ou pesquisas de DNS para IPs externos falham. O MIP & Mapa VIP para ele funciona perfeitamente - eu posso acessá-lo através de HTTP e RDP sem problemas.
Alguma dica sobre o que depurar ou onde eu estraguei minha configuração?
Eu anexei a configuração completa aqui (com IPs anônimos):

Atualização:
Assim como o problema aparentemente surgiu sem eu ter alterado as configurações, ele desapareceu também. Saí do escritório às 9 da noite de ontem, não tendo encontrado uma solução para o servidor .202 não poder acessar o exterior. Quando eu apareci esta manhã, estava funcionando de novo - e nada havia sido tocado desde que saí.
Poderia ser uma questão de tempo de conexão, novas concessões de DHCP ou algo assim? Estaremos tentando reconectar o novo SSG5 mais uma vez hoje à noite - desta vez, estou pensando que ele pode realmente funcionar, mas estamos enfrentando os mesmos problemas com base no tempo.
