Login with WinSCP (if you've not used that before, see here viewtopic.php?t=8505)
Navigate to /www/
Open the file dhcp.sh in the text editor (double click).
Ctrl+F to find the following phrase (including the quotes): id="dhcpv6"
Below that you will see 3 lines beginning with <option...
The one that says "relay", you will see the word disabled next to the > symbol.
Remove the word disabled so it just reads <option value="relay">...
So you'll have OLD:
Code: Select all
<option value="server"><%~ Enabled %></option>
<option value="relay" disabled><%~ Relayed %></option>
<option value="disabled"><%~ Disabled %></option>
Code: Select all
<option value="server"><%~ Enabled %></option>
<option value="relay"><%~ Relayed %></option>
<option value="disabled"><%~ Disabled %></option>
Save and close the file.
Now in your browser go back to the Connection->DHCP page and those dropdowns will no longer have the middle option disabled. Set them both to "Relayed" and save your settings.
