Hi Bogdan, Thanks for the suggestions!
So this means we´ll need new "listen" lines, right? Plus, we´d need some mechanism to round-robin through the destinations sockets - like dispatcher? We´re also using force_send_socket(). Will we need to round-robin through the many ports we´re listening as well and choose one to force, or can we keep only one socket for that? In other words, could OS1 use only 1 output interface and still create multiple connections (given that OS1 is sending each call to a different OS2 interface at a time)? Thanks again. Mariana.
