Re: [Boost-users] udp with virtual network cards

If you by "virtual network card" mean "loopback adapter" this is not a boost/asio issue, but caused by changes to TCP/IP stack in recent Windows version. You'll need to enable weak host receive/send on the interfaces: http://blog.loadbalancer.org/direct-server-return-on-windows-2008-using-loop...

I mean the network adapter created by a virtualization tool (like VMware). I verified that a client on win7 with a such network adapter active does not work (I'm talking about udp multicast, while TCP works perfectly). On the other side if I disable the "real" card and then enable it again, udp starts magically working. Any idea? Regards Gianni
