FTP not working with CISCO 877

I have been trying to get my FTP server working for months with no joy. It works when I connect to it internally but not from outside. If I do a port scan, I can see that port 21 is open. I tried it with disabled firewalls and also checked with ISP that nothing is being blocked. I have attached the config file. Would appreciate any help on this as it is driving me crazy. I used several differnet FTP servers such as CoreFTP, Wing FTP etc. Thanks, Simon

Can you open port 21 from the router? From the CLI of the Router enter this command and hit enter. What happens?

telnet 192.168.1.250 21

Hi Pompeychimes,

Yes that works.

DISEEM#telnet 192.168.1.250 21

Trying 192.168.1.250, 21 ... Open

220 Wing FTP Server ready... (UNREGISTERED WING FTP SERVER)

Now source it from the outside interface of the Router...

telnet 192.168.1.250 21 /source-interface atm0.1

what happens?

Same thing, seems to be fine.

DISEEM#telnet 192.168.1.250 21 /source-interface atm0.1

Trying 192.168.1.250, 21 ... Open

OK, from device on the Internet or a site like this http://ping.eu/port-chk/ try to open ftp. Meanwhile on the router look at the output of the "sh ip nat trans" command. Do you see a translation for your ftp attempt?

I'll assume these are your attempts...

tcp 198.200.18.60:21      192.168.1.250:21      88.198.46.51:35611    88.198.46.51:35611

If so it looks good.

Is your FTP Server's DFG 192.168.1.254?

What actually happens when you attempt the FTP. Does is just hang, do you get a header, a prompt for credentials maybe, etc...

Hi james,

Yes.

It gives me :

500 Connection refused (Winsock error #10061) which is odd, because it works from inside to username and password definitely correct.

How does one do PMs in here? Maybe I can give you access and you could try from your end?

Thanks,

Simon

I was able to login. I replied to your PM.

its so bizzare, I still can't. I tried with FTP Commander and filezzila and a different internet line. I am using windows 7. Could windows block something? Although I can log onto other FTP servers. So odd

hi,

could you re-configure static NAT to use the WAN IP instead and try again from outside? make sure FW/AV are disabled when doing your test.

no ip nat inside source static tcp 192.168.1.250 21 interface ATM0.1 21

ip nat inside source static tcp 192.168.1.250 21 198.200.18.60 21

hi simon,

i guess your config should be ok. i think your next option would be an IOS upgrade.
