Hi,
I have a linux box which balances load between two interfaces ( say WAN1
and WAN2). I have masquerading on for any request coming from LAN to the
outside world.
The setup is in such a way that WAN1 drops packets with source ip
belonging to WAN2's network and viceversa.
For some strange reason, I find that packet coming out from the WAN
interface has source address of WAN2 and thereby getting dropped.
When I check the route cache , I find that for the same source and
destination, I have two route cache entries
192.168.52.66 192.168.26.73 192.168.19.76 0 0 0 eth1
192.168.52.66 192.168.26.73 192.168.20.25 i 0 0 23 eth2
Here 192.168.19.76 is the WAN1 gateway and 192.168.20.25 is WAN2
gateway, as we see the packets are going out through WAN2 , but the
masquerading has happened to the WAN1 IP address.
It seems to me that the root of the problem is the creation of the two
cache entries. Any idea why this happens, and how it can be avoided.
Thanks and Regards,
Vinod C
