Cisco IOS nat può essere usato con il protocollo router di standby hot (HSRP) Per fornire collegamenti ridondanti a un ISP?

SÌ. NAT does provide HSRP redundant. Tuttavia, it is different from SNAT (Stateful NAT). NAT with HSRP is a stateless system. The current session is not maintained when failure takes place. During static NAT configuration (when a packet does not match any STATIC rule configuration), the packet is sent through without any translation.
