Re: PPPoE FTP ASA 5505

jill.kane · ‎02-22-2011

We are trying to set up our ASA 5505 that is running PPPoE so that we may access our ftp site using 99.23.119.78 to reach internal ip 192.168.1.3. Can someone tell me what I am missing?

Here is my current config:

Hi Jill,

What part of the config isn't working for you? Let us know where you're stuck and we can provide some guidance on how to troubleshoot.

We are unable to reach our FTP site by browsing to ftp://99.23.119.78. Internally we are fine but our customers need to access the ftp site.

Can you test and provide any feedback, please and thank you!

mirober2 · ‎02-22-2011

Hi Jill,

Everything on the ASA seems to be correct. In fact, I can FTP to your server and get a login prompt:

C:\Users\mirober2>ftp 99.23.119.78
Connected to 99.23.119.78.
220 192.168.1.3 FTP server ready
User (99.23.119.78:(none)):

Could the problem be on your customer's side?

I am unable to test the ftp site using the external ip address 99.23.119.78 from inside the network. Do you know what I have to do to

route this?

Also, there is a port for utilizing a web gui using port 9000 but we would like to actually be able to not have to enter the port number and just have an http url go directly to the gui by the following url: http://www.fileshare.3eos.com. We were previously able to use the web url as http://www.fileshare.3eos.com:9000.

Please let me know...

Hello,

I dont think you should be using the following static

static (inside,ATT) interface 192.168.1.3 netmask 255.255.255.255

As you may have internet connectivity.....

However, if you want to use the FTP using the public IP, what you would need to do is the following

static (Inside,inside) 99.23.119.78 192.168.1.3

nat (inside) 1 0 0

global (inside) 1 interface

same-security-traffic permit intra-interface....

Let me know how it goes.

Mike

Well I tried your suggestion and that didn't work. I am still unable to reach our ftp site internally by using the external IP address.

I am also trying to forward any http request to port 9000 so that when our customers connect to our ftp's web interface they don't have to enter the port number in the url http://99.23.119.73:9000 I'd like for the customers to just be able to access http://99.23.119.78.

My current config is as follows:
