Problems with mount

[Yair Zohar]

Hello,
I'm using FC2 connected by cables from home.
I'm trying to mount :
[root#] mount -t nfs 132.64.50.50:/usr/local/eclipse/workspace 
/mnt/ardEclipse/

after long time it response:

mount to NFS server '132.64.50.50' failed: server is down. 

I also tried :

[root#] mount -o nfsvers=2 132.64.50.50:/usr/local/eclipse/workspace 
/mnt/ardEclipse/

and :

[root#] mount -o nfsvers=3 132.64.50.50:/usr/local/eclipse/workspace 
/mnt/ardEclipse/

with no response.

the same command :
[root #] mount -t nfs 132.64.50.50:/usr/local/eclipse/workspace/ 
/mnt/ard1_eclipse/
works fine from a rh9 that is connected to the same LAN as the server.

also
[root #] rcpinfo -p 132.64.50.50
gives no response.
while the same cmd from the LAN connected RH9 returns:

No known firewall on the RH9 nfs server.
No known firewall on the FC2 client.

The /etc/exports file on the nfs server:

/usr/local/eclipse/workspace 128.139.15.95(rw)
/usr/local/eclipse/workspace 132.64.34.48(rw)

the first line is the rh9 that can mount, the second is for the FC2 that 
can't mount
(the FC2's IP is given by a dhcp server but I set it in the server's 
/etc/exports/ and than restarts the nfs server).

That's the ifconfig of the FC2 client :

Any idea ?
Thanks.
