            Bug ID: 93861
           Summary: Problem in source route of interfaces
           Product: Networking
           Version: 2.5
    Kernel Version: 3.10.0
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: IPV4
          Assignee: shemminger@...ux-foundation.org
          Reporter: kidboy@...urbo.com.br
        Regression: No

I have 2 internet links, where do a test to assess the connection applying a
ping on each output interface and getting the result, in version 2.6.XX i can
ping and route source works fine, but in kernel 3.X.XX its not work anymore, i
dont know why.

My configuration is here:

/etc/sysconfig/network-scripts/ifcfg-eth0
TYPE="Ethernet"
BOOTPROTO="static"
IPV4_FAILURE_FATAL="no"
NAME="eth0"
UUID="68ec71ab-62f4-41fc-9ad8-085bb3b78eae"
ONBOOT="yes"
HWADDR="10:FE:ED:07:B3:38"
IPADDR="192.168.25.2"
GATEWAY="192.168.25.1"
PREFIX="24"
NM_CONTROLLED="no"

/etc/sysconfig/network-scripts/ifcfg-eth1
TYPE="Ethernet"
BOOTPROTO="static"
IPV4_FAILURE_FATAL="no"
NAME="eth1"
UUID="6ddee48f-3296-4158-86e6-d4104593d942"
ONBOOT="yes"
HWADDR="50:E5:49:FB:AF:0D"
IPADDR="192.168.26.2"
GATEWAY="192.168.26.1"
PREFIX="24"
NM_CONTROLLED="no"

# /etc/rc.d/rc.local ( Permission is 755 in file )
ip route add 192.168.25.0 dev eth0 src 192.168.25.2 table 1
ip route add default via 192.168.25.1 table 1

# Rules for out ADSL1
ip route add 192.168.26.0 dev eth1 src 192.168.26.2 table 2
ip route add default via 192.168.26.1 table 2
# Rules for out ADSL2
ip route add 192.168.25.0 dev eth0 src 192.168.25.2
ip route add 192.168.26.0 dev eth1 src 192.168.26.2
# Rule for tables
ip rule add from 192.168.25.0 table 1
ip rule add from 192.168.26.0 table 2
ip rule add fwmark 1 lookup 1
ip rule add fwmark 2 lookup 2
ip route flush cached


So if i use command 'ping -I192.168.25.2 8.8.8.8' its work fine because its the
default route of system, but if i use command 'ping -I192.168.26.2 8.8.8.8' its
not work, in tcpdump report its out using lo interface. In kernel 2.6 the
output of tcpdump is the interface 192.168.26.2 and works fine. I dont know
what change for new kernel or if its a bug. The forwarding is enable,
configuration in kernel 2.6 and 3.x is the same.
