It is recommended to reinstall the system at the control panel after product activation to add all IPv6 Subnets.
To toggle the unlocked region:
1. ip -6 route (default via AAAA dev BBBB, AAAA~Gateway, BBBB~NIC)
2. ip -6 addr (to see the IP address bound on the BBBB NIC)
73b1:1:XXX/112 for HK Region Unlock
73b1:2 for SG
73b1:3 for TW
73b1:4 for JP
3. ip -6 route replace default via AAAA dev BBBB src CCCC
(AAAA/BBBB is the information viewed in 1 and CCCC is the IP address viewed in 2)
You can also specify the source IP of the network outbound directly in the application.
