As of 6/12, 2019, zLink zChamber functions do not apply to Linux IPv6 environment in current releases. The zChamber functions in Windows environment are implemented using Microsoft Windows Firewall and thus are not in the scope of this article. The plan is to address this issue in 5.1.1.
For IPv6, a very good resource can be found here: Linux IPv6 HOWTO
Chapter 4 in the above document lists IPv6-ready system check including
Network configuration readiness
Test and debug programs like ping6, traceroute (or old traceroute6), tracepath6, tcpdump
Chapter 5 is about how to bring the interfaces up and down. However, the command usage below will likely stop traffics over the interface for not only IPv6 but also IPv4.
# ip link set dev <interface> up
# /sbin/ifconfig <interface> down
