ok, what happens is that I am using pub IPs and can not show them here. I had to edit the output of the "ifcfg-ethX" files and of course I messed up 2 times, :-(.
this should be the right information, sorry again.
eth1 --> 192.168.1.10 255.255.255.0
eth2 --> 192.168.1.11 255.255.255.0
[root@proxy2 network-scripts]# cat ifcfg-eth1

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
