iptables rules that match packets based on their security contexts is a
bad idea for several reasons. For a discussion of these reasons, a list
of alternative resources, examples, and a netfilter module that will do
what you're asking for if you decide to ignore the reasons why this is
bad and do it anyway, see https://github.com/markmont/xt_selinux
If at all possible, use the advice Dan already sent:
I am not sure about proxying, but you can force all packets from the
sandbox to go to a proxy server and block them if they tried to go direct.
