Connect to FTP Server

I have an FTP server located at my office that is connected to a local
router in the office area, this router is connected to another router on the
floor and that router is connected to the main router where the ISP comes
into the building.

Not my design, just a user here.

Since my local router is at 192.168.1.1 and probably one or more of the ones
above me are at the same address and all using DHCP, how can I get to the
ftp server in my office from home? Can I determine the route and then
establish the route as a fixed address?

And how?

TIA

The short answer is no. You are on a private network, and private
addresses cannot be routed through the Internet. From home you could only
connect to the outermost router which connects to the Internet and has a
registered public IP.

You would have to route/forward incoming traffic from router to router until
it gets to the FTP server. For modern FTP communications that's port 21 and
a passive port range you define; I recommend the 2000 block. That requires
that those ports are available on at least one public IP address for your
network's primary router and you have the ability to set up the routes.

As an alternative you should try to move your FTP server to a more "server
friendly" location were it can have a 1-to-1 NAT with a public address behind
a firewall.
