FTP on ASA 5510

jerrybu01 · ‎01-16-2013

I have the system: Internal <--> Switch <---> Router cisco 2911 <---> ASA 5510 <---> Modem

I built FTP server in internal, when i check FTP acccount in internal by IP FTP server -->ok

So now i want to config FTP can access from internet. i have 1 IP static and domain, i also config already.

i config on ASA:

ASA5510(config)# policy-map global_policy

ASA5510(config-pmap)# class inspection_default

ASA5510(config-pmap-c)# inspect ftp

When i access FTP from internet i just see login, but i can't access

Help!!!!

If you get the login-prompt but can't login, then the FTP control-channel is fine up to your server. You should see a logging-message on the server that gives you more info.

Or did you mean with "can't access" that you can login but you can't down- or upload files or can't do a directory-listing?

Then the data-channel doesn't work. In that case show the result of the following command:

asa# show service-policy

and also the config of the router.

Hi karsten.iwen,

Config on Router:

R2911(config)#access-list 102 permit tcp any host 192.168.1.100 eq ftp

R2911(config)#access-list 102 permit tcp any host 192.168.1.100 eq ftp-data established

R2911(config)#access-list 102 permit tcp any any eq 21

R2911(config)#access-list 102 permit tcp any any eq 20

Config on ASA:

ASA5510(config)# policy-map global_policy

ASA5510(config-pmap)# class inspection_default

ASA5510(config-pmap-c)# inspect ftp

when access from internet ftp://"domain name"

i see login-frompt but i can't enter username and password,when is use firefox it says "550 permission denied"

you try acccess:

ftp://atclohoi.com.vn

username: ftpadmin01 / password: 123456

Error 550 is caused by the server. You have to troubleshhot it there.

Error: connection time out

Timeouts are usually caused by some router and/or firewall that is interrupting the connection.

Try uninstalling all firewalls and plug your computer directly into your modem, thus bypassing the router
