Hi,

I have one server, with double NICs connected to one switch with the same gateway. Behind the switch we have internet.

|Debian| -> eth0 -> switch -> internet -> eth1 -> same

I don't understand how to load-balancing between eth0 and eth1. The inbound/outbound traffic always use eth1.

This is the config:

# The primary network interface
allow-hotplug eth0
auto eth0
iface eth0 inet static
address 192.168.248.82
netmask 255.255.255.240
network 192.168.248.80
broadcast 192.168.248.95
gateway 192.168.248.81

allow-hotplug eth1
auto eth1
iface eth1 inet static
address 192.168.248.83
netmask 255.255.255.240
network 192.168.248.80
broadcast 192.168.248.95
gateway 192.168.248.81

Kernel IP routing table

Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.248.80 0.0.0.0 255.255.255.240 U 0 0 0 eth1
192.168.248.80 0.0.0.0 255.255.255.240 U 0 0 0 eth0
0.0.0.0 192.168.248.81 0.0.0.0 UG 0 0 0 eth1
0.0.0.0 192.168.248.81 0.0.0.0 UG 0 0 0 eth0

Ips aren't real, it's just for the example.

Anybody have an idea on correct routing to use eth0 on 192.168.248.82 and eth1 on 192.168.248.83 ? I have many example for multiple gateway but here it's the same.

Thanks all.

Regards
