[KLUG Members] no route to local network?

[Mike Williams]

I'm trying to set up an old 500mhz box as a cable modem gateway running 
Suse 9.2.  It gets a DHCP address just fine from the cable modem, but 
doesn't work on the internal LAN.  It seemed to work fine internally 
until I gave it a static IP, then it completely chokes.  It can ping 
itself by IP address, but reports "no route to host" when i try to ping 
anything else, even an adjacent IP.  This occurs even when I disable the 
outside NIC.  Anybody have a clue what could cause this?  Here's the 
routing table, which looks fine to me.  What am I missing?

Destination            gateway               mask            
flags        interface
192.168.41.0           *           255.255.255.0         U               
eth0
link-local                    *          255.255.0.0             
U              eth0
loopback                    *           0.0.0.0                     
U             eth0
default                         *           0.0.0.0                    
UG          eth0
