I have the following problem. First of all. Here are my interfaces.
# ip addr
ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff
inet 10.10.1.15/24 brd 10.10.1.255 scope global eth1
inet6 fe80::a00:27ff:fe28:b0c4/64 scope link
valid_lft forever preferred_lft forever
As you can see the loopback interface serves following network 127.0.0.1/8
, the network mask is 255.0.0.0
.
My problem is that I need to route all traffic for example for the network 127.22.0.0/16
to the interface eth1
.
I have following routes now
default via 10.10.1.2 dev eth1
default via 10.10.1.2 dev eth1 metric 203
10.10.1.0/24 dev eth1 scope link
10.10.1.0/24 dev eth1 proto kernel scope link src 10.10.1.15 metric 203
10.10.1.2 dev eth1 scope link
And I try to add the following route
ip route add 127.22.0.0/16 via 10.10.1.2 dev eth1
But unfortunately it doesn't work.
Here is the output
root@sys:/ # ip route flush cache
ip route flush cache
root@sys:/ # ip route get "127.22.0.1"
ip route get "127.22.0.1"
local 127.22.0.1 dev lo src 127.0.0.1
cache <local>
As you can see all packets are still redirected to loopback.
What is the best solution for that problem ?
