> Why the interface need to be in 'default route'? Thanks.

As sugested by a private reply, i've disabled 'rp_filter' and packet
flow correctly.

AFAI've understood, packet get routed correctly to the intended
interface, but when reply come back the reverse path filter interpret
it as 'impossible' (because there's no a forward route, and this is
true indeed), and filter it away.


There's some 'smarter' way, or fine-grained way, or i have to disable
rp_filter as the only option?


Thanks.
