🚧Configuración de NAT/PAT

NAT  
Static NAT 
R1(config)#ip nat inside source static [inside local] [inside 
global] 
Ejemplo 
R1(config)#ip nat inside source static 10.1.1.1 192.168.1.2 
R1(config)#interface ethernet 0 
R1(config-if)#ip address 10.1.1.1 255.255.255.0 
R1(config-if)#ip nat inside 
R1(config)#interface serial 0 
R1(config-if)#ip address 192.168.1.1 255.255.255.0 
R1(config-if)#ip nat outside 
Configurando Dynamic NAT 
R1(config)#ip nat pool [name] [first address] [last address] 
netmask [subnet-mask] 
R1(config)#ip nat inside source lista acl-number pool pool-name

R1(config)# ip nat pool nat-pool 179.9.8.80 179.9.8.95 netmask 
255.255.255.0 
R1(config)#ip nat inside source list 1 pool nat-pool 
Configurar PAT OVERLOAD 
R1(config)#ip nat pool [name] [ip address] netmask [subnet-mask] 
R1(config)# ip nat inside source list [acl-number] interface 
type/number overload
