Issues with FTP ASA 5505

[jill.kane]

I am unable to get inbound ftp working. Here is my current running configuration. Can anyone help me? All I want is to ftp to the external ip address and have it hit the internal ftp server address of 192.168.1.3.

[Federico Coto Fajardo]

Hi,

This line should reference the public IP (instead than the private IP):

access-list outside_access_in extended permit tcp any host 192.168.1.3 object-group DM_INLINE_TCP_1

Federico.

[jill.kane]

Still no luck... any other ideas?

I can ftp internally when connected to the local ip. However, going to ftp://99.23.119.78 it times out.

Result of the command: "show running-config"

[jill.kane]

I see that I am now getting hits in the ASDM but they are not coming through. What else should I change?

Any help would be greatly appreciated...

Thanks!

[manish arora]

Hi Jill,

Can you post sh service-policy output ?

manish

[jill.kane]

I'm relatively new to this Cisco... so please bare with me. I ran the command "show service-policy" and it returned nothing but the standard prompt. Is there anything else I should be doing?

[manish arora]

try this :-

asa(config)# service-policy golbal_policy global

Then test your ftp from outside network ( From client side )

Then  do sh service-policy

Manish

[jill.kane]

Still no connection.

I ran sh service-policy and this is the output:

Global policy:
  Service-policy: golbal_policy
    Class-map: inspection_default
      Inspect: ftp, packet 0, drop 0, reset-drop 0

Anything else?

It seems the ftp traffic is coming to the right place, its just not being sent to the internal ip address - thus never prompting for a login.

I see that there are hits.

[manish arora]

Jill,

Is this the correct ip address that you are using 99.23.119.78 ?

Externally it only show port 443 & 22 open.

Manish

[jill.kane]

That is correct... the ip is 99.23.119.78.

How do I open port 21 for ftp?

Once again, this is the running config:

[Federico Coto Fajardo]

One question... when you attempt the FTP connection do you get an error on the client?

Are you able to FTP to your server from the inside (inside the ASA)?

Federico.

[jill.kane]

Inside the network I am able to ftp to ftp://192.168.1.3 and am prompted for credentials and am able to gain access.

And regardless of if I am inside the network or outside when try to ftp to ftp://99.23.119.78 it is unable to connect. It times out and is unable to access the folder; a connection with the server could not be established.

Try it out yourself and let me know.

Thanks, I really appreciate the help! I've been trying to get this to work for about 5 hours today and it shouldn't be that difficult!

[manish arora · Accepted solution]

Last time I saw your config you had :-

"static (inside,outside) tcp interface ftp-data 192.168.1.3 ftp-data netmask 255.255.255.255
static (inside,outside) tcp interface ftp 192.168.1.3 ftp netmask 255.255.255.255"

where are these lines now ?

if they are not there , then please add these lines :-

static (inside,outside) tcp interface ftp-data 192.168.1.3 ftp-data netmask 255.255.255.255
static (inside,outside) tcp interface ftp 192.168.1.3 ftp netmask 255.255.255.255

also

static (inside,outside) tcp interface 80 192.168.1.3 80 netmask 255.255.255.255

then clear xlate

Manish

[jill.kane]
