Ports Forward on Cisco Router

Hi guys,

I have a router 1802 with a several vlans with IP 192.168.x.0/24 for each vlan (x, it meaning 1, 2, 3, 4, etc.).

Now I need that an IP address outside from my network (this IP it is always the same) to be access to on particular machine that is in a private network (192.168.3.0/24) through a several ports:

25 (TCP,UDP), 80 (TCP,UDP), 554 (TCP,UDP), 2000 (TCP,UDP), 10002 (TCP,UDP), 10000 (TCP,UDP), 3000 (TCP,UDP), 3041 (TCP,UDP)

How can I do it?

Outside PC ---------Internet ----MyRouter -----MyParticularPC

83.240.194.99                            193.136.80.1              192.168.3.1

Thanks in advanced,

António

Hi,

on internet interface(interface x/x) : ip nat outside

on the vlan interface : ip nat inside

ip nat inside source static tcp 192.168.3.1 25 interface x/x 25

ip nat inside source static udp 192.168.3.1 25 interface x/x 25

ip nat inside source static tcp 192.168.3.1 80 interface x/x 8081

ip nat inside source static udp 192.168.3.1 80 interface x/x 8081

ip nat inside source static tcp 192.168.3.1 554 interface x/x 554

ip nat inside source static udp192.168.3.1 554 interface x/x 554

ip nat inside source static tcp 192.168.3.1 2000 interface x/x 2000

ip nat inside source static udp 192.168.3.1 2000 interface x/x 2000

and so on for other ports

Regards.

Alain
