Port forwarding NAT

Berikut ini contoh nat di router cisco , sesuaikanlah dengan interface dan ip anda :

Interface WAN :

interface GigabitEthernet0/1
ip address 222.222.222.4 255.255.255.248
ip nat outside
no cdp enable

!

Interface Lokal :

interface GigabitEthernet0/2
ip address 192.168.3.250 255.255.255.0
ip nat inside
no cdp enable

Untuk Nat nya :

access-list 1 permit 192.168.3.0 0.0.0.255

ip nat inside source list 1 interface GigabitEthernet0/1 overload

Pasang Gateway nya :

ip route 0.0.0.0 0.0.0.0 222.222.222.1

Untuk forwarding port nya (forward port 1933 ke port 5900 internal ) :

ip nat inside source static tcp 192.168.3.30 5900 interface GigabitEthernet0/1 1933
