Estou tentando NAT um endereço externo para um endereço interno que não é local, mas em um ponto remoto de uma conexão VPN site a site. Isso é possível? Log diz O roteamento falhou ao localizar o próximo salto para o TCP de fora x.x.x.x / xxx para o interior: y.y.y.y / yyyy
Eu posso me conectar ao endereço y.y.y.y, então a VPN está funcionando.
