Hi,

Your config says differently:

<quote>
 [root@proxy2 network-scripts]# cat ifcfg-eth0
 # Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet
 DEVICE=eth0
 BOOTPROTO=none
 BROADCAST=192.168.1.255
 HWADDR=00:19:b9:f2:f3:f4
 IPADDR=192.168.1.10
 NETMASK=255.255.255.0
 NETWORK=192.168.1.0
 ONBOOT=yes
 GATEWAY=192.168.1.1
 TYPE=Ethernet
</quote>

Thanx,
Jaap
