I am trying to achieve this scenario but I am little confuse as how it is done.
I have installed a FTP server which is a member of my domain. The server has internal IP address and it is able to access the internet through the gateway IP. The server is installed behind the firewall. I am good to this point.
The server has a feature for file transfer and I need your help to make this work. The idea is when an internal user should access the server via the webbrowser and send files to outside user. The server has a server portal that will generate an email with a link and send it to the outside user. The remote user will receive the email with the link and download the files.
The file sharing tab is where I put information line domain name or IP, email address - that the remote user will see . SMTP address. Does the IP needs to be the public or internal IP and how to define that in the DNS as I have Two DNS server.
In my infrastructure I have 2 DNS server . First DNS is the internal DNS and 2nd DNS is the DNS used by devices facing the internet.
I am not sure which one shall I populate to make this work.
Lets say my public domain is gts.ca
what shall I put in the domain URL and the change in 1st and 2nd DNS.
SMTP part is clear and the firewall part is clear in which I will map internal ip to public IP that I have.
Thank you for your help.
