In the multiple_IP.pdf, it suggest that we create the following static route:
Destination Gateway Genmask Flags Metric Ref Use Iface
10.10.10.1 0.0.0.0 255.255.255.255 UH 0 0 0 eth0
10.10.10.5 0.0.0.0 255.255.255.255 UH 0 0 0 eth0
10.10.10.6 0.0.0.0 255.255.255.255 UH 0 0 0 eth1
10.10.10.7 0.0.0.0 255.255.255.255 UH 0 0 0 eth2
10.10.10.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
10.10.10.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1
10.10.10.0 0.0.0.0 255.255.255.0 U 0 0 0 eth2
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 10.10.10.1 0.0.0.0 UG 0 0 0 eth0
However, Open-E DSS prompts: Error, Following route is invalid....
Thus, I only manage to setup the first 4:
10.10.10.1 0.0.0.0 255.255.255.255 UH 0 0 0 eth0
10.10.10.5 0.0.0.0 255.255.255.255 UH 0 0 0 eth0
10.10.10.6 0.0.0.0 255.255.255.255 UH 0 0 0 eth1
10.10.10.7 0.0.0.0 255.255.255.255 UH 0 0 0 eth2
