Change route interface if set by custom app via SO_BINDTODEVICE

[ra9ftm]

I have a compiled binary linux application that selects particualar network interface by system call setsockopt(.., SO_BINDTODEVICE,.. ).

I want to change interface.

As for me there can be this options:

• App reverse engineering, patch the binary.
• Patch the linux kernel so it will not pay attention for SO_BINDTODEVICE.
• May be some routing trick with iptables patch-o-matic.

Is it possible to change route interface?
