management network to a network port for additional ones munin and monit

I want to build a separate Netzwek for server management. I have several network cards a linux / debian / ubuntu with computer.

Set both network cards sin in the /etc/network/interfaces.

# The primary network interface
#allow-hotplug eth0
#iface eth0 inet dhcp
auto eth0
iface eth0 inet static
        address 10.0.0.240
        netmast 255.255.255.0
        network 10.0.0.0
        brodacast 10.0.0.255
        gateway 10.0.0.254


auto eth1
iface eth1 inet static
        address 10.0.10.240
        netmast 255.255.255.0
        network 10.0.10.0
        brodacast 10.0.10.255


post-up ip route add 10.0.0.0/24 dev eth0 src 10.0.0.240 table eth0-WAN
post-up ip route add default via 10.0.0.254 table eth0-WAN
post-up ip route add 10.0.10.0/24 dev eth1 src 10.0.10.240 table eth1-LAN
post-up ip route add default via 10.0.10.200 table eth1-LAN
post-up ip rule add from 10.0.0.240 table eth0-WAN
post-up ip rule add from 10.0.10.240 table eth1-LAN

still i adjusted / etc/iproute2/rt_tables

and following routes set up in the /etc/network/interfaces

I want to have both applications and the network interface separately as munin and monit only on eth1 and not have to eth0.

it goes to the reboot but sometimes not always.

# Traceroute-i eth1 10.0.10.200 not go

what am I doing wrong?
