My first thought is you have a routing problem and perhaps your netmask is set wrong. But I cannot be sure.
Are you sure your netmask for your subnetwork is correctly set to 0xffff0000 ? (This seems possibly an error).
Do you have the ability to login to your default router host at 172.16.80.100 and check the netmask there? What is that device?
Normally, we do not see big /16 netmasks in subnetwork devices.
Cheers
I'm afraid i don't have much idea regarding the device as i did not get any sort of handover in terms of the company's network architecture . I'm told that the router in question is the SAP router for people in different locations to access the system.
i tried to telnet into the router.
telnet 172.16.80.100

Cisco Configuration Professional (Cisco CP) is installed on this device.
This feature requires the one-time use of the username "cisco" with the
password "cisco". These default credentials have a privilege level of 15.
YOU MUST USE CISCO CP or the CISCO IOS CLI TO CHANGE THESE PUBLICLY-KNOWN
CREDENTIALS
Here are the Cisco IOS commands.
username <myuser> privilege 15 secret 0 <mypassword>
no username cisco
Replace <myuser> and <mypassword> with the username and password you want
to use.
IF YOU DO NOT CHANGE THE PUBLICLY-KNOWN CREDENTIALS, YOU WILL NOT BE ABLE
TO LOG INTO THE DEVICE AGAIN AFTER YOU HAVE LOGGED OFF.
For more information about Cisco CP please follow the instructions in the
QUICK START GUIDE for your router or go to http://www.cisco.com/go/ciscocp

User Access Verification
Password:
% Password expiration warning.
-----------------------------------------------------------------------
Cisco Configuration Professional (Cisco CP) is installed on this device
and it provides the default username "cisco" for one-time use. If you have
already used the username "cisco" to login to the router and your IOS image
supports the "one-time" user option, then this username has already expired.
You will not be able to login to the router with this username after you exit
this session.
It is strongly suggested that you create a new username with a privilege level
of 15 using the following command.
username <myuser> privilege 15 secret 0 <mypassword>
Replace <myuser> and <mypassword> with the username and password you want to
use.

You should find out what software that router is running and now many interfaces it has, etc.
Did you try:
show version
and
show ip interfaces brief
and maybe even
show ip route
and also:
show access-lists
For starters.....

So, you are not going to get any support from Cisco, I am guessing 
Anyway, back to the task at hand.... while logged into your router, you should try to ping your ftp server (the one you are trying to reach from your host):
ping 164.52.194.12
Can you ping it from (while logged into) the router?

That is not a good sign (cannot ping from intermediate router).
Let's trace the route, then (from the router to your ftp host):
traceroute 164.52.194.12

Thanks for doing a great job working to troubleshoot your own problem, Bruno.
Without a basic network diagram, it is hard for me to advise, since I cannot readily visualize what is going on.
However, so far, it seems we have some potential issues with subnet masks but I'm not convinced that is the issue, since you cannot ping or traceroute from your router.
Your router does not have any access control lists, and so normally we would look at the next hop; but I don't know where your next hop is.
We could try to figure it out with:
show arp
But it would be better if you drew a sketch of the Internet (as a cloud) and where your Internet gateways (for your organizations) attach to the Internet, and the devices / hosts in the path (in your org).
Note: See next post about your "10"net WAN.
Right now, there is no path from your router (where you are logged in) to the Internet, or so it seems from what I have read so far. You have done a good job of showing the details. Thanks for your patience.
Can you ping or traceroute to any device on the Internet from your router? If so, via what interface on your router?
OBTW, Bruno,
Your router shows a serial interface on the "10" network. This leads me to believe or guess (at least) that your router is connected to a private wide area network (WAN).
Is that correct?
