Sets the NAT traversal mode for cisco (vpnc > = 0.4. x) * natt - NAT-T as defined in RFC3947 * force-natt - always use NAT-T encapsulation even without presence of a NAT device (useful if the OS captures all ESP traffic) * cisco-udp - Cisco proprietary UDP encapsulation, commonly over Port 10000
Estabelece o modo transversal de NAT para cisco (vpnc > = 0. 4. x) * natt - NAT- T segundo se define no RFC3947 * force- natt - emprega sempre a encapsulación NAT- T mesmo sen a presenza dun dispositivo NAT (útil se o SO captura todo o tránsito ESP) * cisco- udp - Encapsulación UDP privativa de Cisco, polo xeral no porto 10000
