Conditions to make outbound packets go through this redsocks instance.
If set to false, no packet will be forwarded. If set to true, all packets will be forwarded (except packets excluded by redirectInternetOnly).
If set to a string, this is an iptables filter that will be matched against packets before getting them into redsocks. For example, setting it to "--dport 80" will only send packets to port 80 to redsocks. Note "-p tcp" is always implicitly added, as udp can only be proxied through redudp or the like.
