Controling network/internet access in specfic sandboxes

[mrstrong]

Hi,

I’m trying to run multiple instances of a program in separate sandboxes which is working fine, the program runs in two processes that communicate through a link local address (ie 127.0.0.1) and requires some internet access.
The issue is that if I allow network access under ‘restrictions->internet access’ the application can communicate over the link local address to the other sandboxes as well as any other network available


My question is, is there a way of having a more explicit way of allowing different networks rather than, this process can have complete network access or not at all



Thanks in advance
