<font size=2 face=Arial><span style='font-size:10.0pt;font-family:Arial'>Hi,<br>
Your eth0's network contains of the wlan IP range.<br>
10.0.1.37/16 is part of a network ip range of 10.0.0.1 to 10.0.255.254<br>
Your wlan range is inside that so no routing is performed.<br>
<br>
You want to use a class C range for the wlan, so instead of 10.0.10.0<br>
network,<br>
try using one of the 192.168. class C networks. It may make be best to<br>
use 2<br>
different 192.168 networks (say 192.168.0.0/24 for LAN and<br>
192.168.1.0/24 for<br>
the WLAN).<br>
<br>
Class A 1.0.0.0 - 127.255.255.255<br>
Class B 128.0.0.0 - 191.255.255.255<br>
Class C 192.0.0.0 - 223.255.255.255<br>
<br>
Hope that helps.<br>

Hi Pete<br>
<br>
<br>
I use 10.1.10.0 as network for my wlan0 interface. The both interfaces<br>
seam to be ok: I can run telnet on each network (LAN on eth0 and WLAN on<br>
wlan0). But the problem persists: it's impossible to ping a machine on<br>
LAN area (10.0.2.201) from a machine in WLAN area (10.1.10.2).<br>
The interfaces configurations are:<br>
Eth0:<br>
InetAddr: 10.0.1.37/16<br>
Network: 10.0.1.0<br>
Broadcast: 10.0.1.255<br>
Wlan0:<br>
InetAddr: 10.1.10.1/24<br>
Network: 10.1.10.0<br>
Broadcast: 10.1.10.255 <br>
<br>
L'IP forwarding is active (echo 1 > /proc/sys/net/ipv4/ip_forward).<br>
<br>

I don't understand what happen!!???<br>
Please, can you help me?<br>
<br>
Thank you very much,<br>

<br>
<br>
I'm not sure but I think that my first reply didn't reach RH disc. list<br>
so I'll post it again. <br>
<br>
The network from eth0 isn't correct: it should be 10.0.0.0 for IP with<br>
/16 mask.<br>
<br>
Oups, I make a key error: I agree with you, for eth0, the network is<br>
10.0.0.0 (not 10.0.1.0) and the broadcast is 10.0.255.255.<br>
I'm sorry !<br>
Here are the ifcfg-eth0 & ifcfg-wlan0:<br>
<br>
