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

If the client is on windows XP it works fine. Does anybody know if there is a problem related to Windows 7?

Hi Gianni, 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... -- Best regards, Martin Dyring-Andersen
