IMPORTANT: The quotes around the text may be added automatically for you, or you may have to add them in - we've received conflicting reports and it seems to vary by CPanel version, so just check what happens when you save. It should look like this:
*** Insert "in25" for "default"
Now go to restart services
Restart the DNS Server (Bind)
You will have to wait a few hours for the DNS changes to propagate, but in a short while LeadFWD should be able to verify that your records have been added. Make sure you have clicked the 'Authenticate' button in your account after you have added the records to your DNS zone.
