Hello All,
I am trying to setup a linux box as a forwarding router based of src IP. The
problem is that it does forward the pkts to the intended server specified in
the ip rule, but it also forwards it to the original dst (dst specified in
the pkt).
Here is the setup:
[10.1.0.166]
[192.168.1.225]
|
|
| [A]
[B] |
|-------[10.1.0.63/172.16.1.63] ----------- [
172.16.1.64/192.168.1.65] ---------|
| linux box only has linux-router in
question |
| net.ipv4.ip_forward=1
|
|
|
[10.1.0.167]
[192.168.1.100]
A - is just a linux box doing forwarding for the 2 networks 10.1.x.x - >
172.16.1.x.
B - is the linux router which I want to setup as forwarding.
The pkts come from 10.1.0.166 and .167 -> to 192.168.1.100
I want to setup rules on [B] to forward all pkts with src addr. 10.1.0.166to
192.168.1.225.
And, all pkts from 10.1.0.167 to 192.168.1.100 should still go to
192.168.1.100.
Here are the rules I setup.
[EMAIL PROTECTED] ~]# ip rule sh
0: from all lookup local
32765: from 10.1.0.166 lookup 225
32766: from all lookup main
32767: from all lookup default
[EMAIL PROTECTED] ~]# ip ro sh tab 225
192.168.1.0/24 via 192.168.1.225 dev eth1
The pkts still go to both .225 and .100. I checked on another machine
connected to the same switch as 192.168.1.100 and 192.168.1.225 and its not
receiving the pkts. So, it doesnt seem like the switch is screwing up and
broadcasting the packets everywhere.
I would appreciate any kind of help or pointers.
Thanks for your time.
