Hi,
  I'm tryng to use my alix2c3 (bios 0.99) as a simple rounter with eth0 
and eth1
 From a client (on the eth1 side) I can connect to the router, and from 
there I can connect to the eth0 side, but I can't connect directly from 
eth1 side to the eth0 one.

What can I do? It's a voyage kernel setting or a configuration error?
Thanks
Alessandro

Here the configuration:

client:~# ip route
10.1.30.0/24 dev eth0  proto kernel  scope link  src 10.1.30.2
default via 10.1.30.1 dev eth0

client:~# cat /etc/network/interfaces|grep -v "^#"|grep -v "^$"
auto lo
iface lo inet loopback
allow-hotplug eth0
auto eth0
iface eth0 inet static
       address 10.1.30.2
       netmask 255.255.255.0
       gateway 10.1.30.1



Router:

router:~# ip route
10.1.30.0/24 dev eth1  proto kernel  scope link  src 10.1.30.1
192.168.5.0/24 dev eth0  proto kernel  scope link  src 192.168.5.18
default via 192.168.5.1 dev eth0


router:~# cat /etc/network/interfaces|grep -v "^#"|grep -v "^$"
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
