I have a cisco 1720 that is my DHCP server asa well as the internet gateway. Everything works well except using ftp from command prompt. I can FTP from my browser and transfer files fine. If I go to a command prompt and do ftp I can connect but no transfer. I always get timed out. Any help would be greatly appreciated. Some strings removed for security.

Am I missing something?
Thanks
 
There's no problem if you can connect and transfer/receive files via FTP on your browser or other FTP GUI clients. Since your FTP server is behind a NAT router, you need to use PASV mode which is supported by most FTP GUI clients and even your browser.

Using FTP commands to enter PASV mode is freakin troublesome IMO. You can try to use "literal xxxx" and enter those RAW FTP commands in the following URLs to work with your FTP server.


e.g.

literal pasv

But I never try that cos it wastes my time.

If you can't even use your FTP GUI clients/Browser, then we should start checking the NAT settings.
 
Hi Dawg

Try this:

Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#no ip ftp passive
Router(config)#^Z
Router#
02:19:26: %SYS-5-CONFIG_I: Configured from console by console
Router#
