Mengganti Hostname

Router>enable

Router#conf t

Router(config)#hostname R1

Menambahkan Password

R1(config)#enable secret fauzan

Menambahakan IP Interface g0/0

R1(config)#int g0/0

R1(config-if)#ip address dhcp

R1(config-if)#no shutdown

R1(config-if)#end

Pengujian IP untuk Interface g0/0

R1#ping 192.168.24.148

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 192.168.24.148, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms

R1#ping google.com

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 216.239.38.120, timeout is 2 seconds:

Success rate is 100 percent (5/5), round-trip min/avg/max = 42/42/43 ms

Settingan NAT Outside g0/0

R1#conf t

R1(config)#int g0/0

R1(config-if)#ip nat outside

R1(config-if)#exit

#####Konfigurasi IP Address g0/1#######

R1(config)#interface g0/1

R1(config-if)#ip address 192.168.10.1 255.255.255.0

R1(config-if)#no shutdown

R1(config-if)#exit

Konfigurasi DHCP-Server g0/1

R1(config)#service dhcp

R1(config)#ip dhcp pool smk

R1(dhcp-config)#network 192.168.10.0 255.255.255.0

R1(dhcp-config)#default-router 192.168.10.1

Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP

       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2

       E1 - OSPF external type 1, E2 - OSPF external type 2

       i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2

       ia - IS-IS inter area, * - candidate default, U - per-user static route

       o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP

       a - application route

       + - replicated route, % - next hop override, p - overrides from PfR

Gateway of last resort is 192.168.24.1 to network 0.0.0.0

S*    0.0.0.0/0 [254/0] via 192.168.24.1

Settingan NAT g0/1

R1#configure t

R1(config)#interface g0/1

R1(config)#ip nat inside source static 192.168.10.11 192.168.24.148

R1(config)#exit

R1# show ip nat translations

Pro Inside global      Inside local       Outside local      Outside global
