Hi,

I'm trying to use aliased interfaces to run multiple instances of a 
process that receives UDP broadcasts; I want to test all in a single 
computer when I have no access to the network.

My problem is that I can bind to the virtual interface ip to send and 
receive packets, but I don't receive udp broadcasts. I have no firewall 
rules that block it and udp bcasts are generated from the same computer 
too.

Is there any sysctl param I need to change? I'm usre this can be done but 
I haven't found how.

Thanks
Pau
