16 If this is only chroot, you have to set all iptables rules (and
17 other network configuration) in the host system environment (on
18 Android). If you are using LXC or other container, involving
19 network namespace separation (not sure this is doable on Android,
20 kernel must support NET_NS as well as userspace tools should
21 support this), then you have to set up network inside container and
22 bridge/route it with the host system.
