2016-12-30 Thread Olivier Brunel
Hi, (Please cc me as I'm not subscribed to the list, thanks.) I'm trying to set things up using some policy routing, and having some weird issues I can't really explain. It looks to me like there might be a bug somewhere... This is done under Arch Linux 64bits, iproute2 4.9.0 (`ip -V` says ip
