Hi,

I got a problem with my ftp server. If I ping my ftp site from my internal network , instead of replying with the IP address of my ftp server, it shows public IP address. what do you think is the problem and how to solve it.? thanks in advanced.

Setup split DNS for the URL of the FTP server so it resolves to the internal IP address
like so;

The problem is your DNS setup. Either the client is using an external DNS server or you don't have your local DNS server setup to resolve the host properly.


If you're trying to get to ftp.company.com, your local DNS server needs to host the zone company.com (or ftp.company.com) with the appropriate records for the local FTP server.

If that is already setup then the client is most likely querying an external DNS server instead of the local DNS server. My guess, since it only happens some of the time, is that the client has an external DNS server configured in the TCP/IP properties.

When you ping a name, the DNS server is queried and it returns the IP address of the remote machine. So what Pete is saying is correct, this is a DNS issue.

I agree with the split DNS configuration suggestion.
In a split zone, you configure the Internal DNS name to point to your internal IP and the external DNS name will still point to the external IP.
So there is no impact to external users and Internal DNS is only available to internal users.
