FTP Server with Cisco 675?

[Maverick]

Hey there,

I'm sure Russ will be first to answer this question, but he hasn't enabled PMing so I'm posting this topic.

I'm running a DSL connection with qwest through a Cisco 675 router. The router is connected to a switch, and the switch is connected to 5 computers. I would like to host an ftp server on one of these computers. I've figured out the FTP programs, but for some reason they list the IP as 10.0.0.2 so that its inside the network. This does not allow computers outside the network to access the FTP server. I tried using the Cisco 675's IP address, but that did not work. Do I need to buy a router to do this? I thought the Cisco had a built in router. Any help would be greatly appreciated.

Is your router acting as a NAT? or you getting multiple IPs addresses from your ISP? If you using NAT, you need to redirect ftp to your internal ftp ip address. Post more details. 🙂

Telnet into your router and add the following:

set nat entry add 10.0.0.2 21
set nat entry add 10.0.0.2 22

If you plan to keep the ftp server permanently on that system add this after the nat entries:

write
reboot

edski: I believe that's port 20 and 21. 22 is for ssh ann/or telnet (22 and 23), but maybe he's using another port above 1024 for his ftp...

Dark: I'm using the router as a NAT, so I only get one IP address from my ISP.

Edski: thanks for the info. I am trying to use a port above 1024 for FTP, what settings do I have to change?

Thanks a lot guys.

Shiva: I don't know about the command edski listed but here is how I usually do it: "ip nat inside source static tcp 10.0.0.2 X Y.Y.Y.Y X Where X is the port you're using to set the FTP server and Y.Y.Y.Y is the address the ISP gave you.
This is gonna redirect all the outside initiated connection to port X to the internal address 10.0.0.2 at port X.

I actually got edski's command to work with the port I was looking to use.

Thanks a lot guys.
