Does it work with rp_filter=1 now again? In recent kernels with this commit:

(git commit 27fed4175acf81ddd91d9a4ee2fd298981f60295
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=27fed4175acf81ddd91d9a4ee2fd298981f60295)

they changed the behavior so that you needed to set it to 0 or 2, or
packets would not be delivered to the initiator when using iface binding
which uses SO_BINDTODEVICE.
