Re: [Qemu-discuss] Unable to do UDP communication

[Anshul]

May be problem is with SLIRP module of qemu
like what vbox had before 
https://www.virtualbox.org/pipermail/vbox-dev/2007-May/005795.html

I am not that smart in networking, as user in the above link.
Not very good in networking was the only reason to choose slirp instead 
of other network module.

If anyone here dont know the solution that is ok to me.
but atleast give me some pointer to pin point and correct my problem
