route or ipforward problem

[Poul Moller]

Hi all,

I'm having a simple network but a strange problem that need some experts 
eyes. My FC2 server that serves as a LTSP server has two "legs" in 
different networks:

eth0: 10.0.0.1/24 (student network for thin clients)
eth1: 192.168.1.10/24 (school network with Internet access router at 
192.168.1.1)

Here come the challege: On the server I can ping all hosts EXCEPT the 
router 192.168.1.1 (the default gateway) ????????? The router is 
perfectly alive and all hosts on the 192.168.1.0  net has Internet 
access except the FC2 server. There must something I completely miss. 

NOTE: the last line (default gw) in the "netstat -r" command takes 10 
sec to display !!!!!!!!!

Any hint is greatly appreciated
Poul
