+Step 2) Navigate to System->Advanced->Networking in webConfigurator.
+
+IPv6 Options
+    DHCP6 DUID: DUID-EN
+    DUID-EN
+        Enterprise Number: 3561
+        Identifier: As shown above
+
+Click Save.
+
+Step 3) Navigate to Interfaces->WAN in webConfigurator.
+
+General Configuration
+    IPv6 Configuration Type: DHCP6
+    MAC Address: Same as MAC address of RG
+
+Other options are probably needed, so set those too.
+
+Click Save. This will finally save dhcp6c's DUID file and start the client.
+
+Step 4) Finished, hopefully.
+
+Good luck!
