curious net behavior

["Claudiu Balciza" <cbalciza geocities com>]

I have a network (I really do).

+----------+   +--------+   +------------+
|a workstn.|<->|internal|<->|masquerading|<->Internet
|          |   |router  |   |router      |
+----------+   +--------+   +------------+

The workstation has the default gateway to the internal router.
The internal router has the default gateway to the masquerading router.
The masquerading router has the default gateway to the Internet.
If the workstation runs windoze it is able to ping and ftp.
If it runs linux, it cannot (DNS works in both cases).
no error for ping, it just waits.
ncftp cannot open the command channel.

what am I missing ?
