Thank you all for help.
Let me summarize issues and solutions.
Internet access:
Problem: Help/About shows "Internet Access Disabled" This does not mean anything except if you are using older router. I hope UDI will fix that in a new firmware.
Solution: Do not use File/Enable internet access if you do not have router listed in in Wiki help.
Instead go to you router virtual server or port forwarding if router do not have virtual server. Type in name (https isy) for your ISY, IP address, port number and select TCP.
Enable virtual server you just created.
UDI suggested that you do this only for https. This will require log in on your remote device.
Alexa interface
Problem: Create account in my.isy.io Click on connection/Alexa Echo and you are getting "ISY is not online"
Solution:You need to buy ISY portal from UDI not network module as I did. In Alexa app or log in online to alexa and select "smart home". Select "Get More Smart Home Skills" and select "Universal devices"
Go to my.isy.io portal, log in, select tools/connect/Amazon Echo. You should see that is connected.
Click "My profile" link Amazon Echo account. You will need to log in to Amazon Echo account. Log off from portal and Log in again.
Click on Tools/Connect/Amzon Echo. Click on Device and start linking devices. Give them spoken commands.
In Alexa app select Discover devices. There should be same number of devices you are linked in portal.
Try to use Alexa to control devices.
If some device do not work try to change spoken command in ISY portal. Select refresh in Portal and repeat Discover devices in Alexa app. I found that longer command works better with Alexa. For example "Backyard light (ON) works better then "Backyard" (ON).
I do not know if in ISY console when right click on device select "Notes" and in "Spoken", the command needs to be same as in ISY portal,
Dashboard on your cellphone will not update and show status of your device when you use Amazon Echo. I hope UDI will fix this in next app revision.
I hope this will help someone.
I spend lot of frustrating hours trying to resolve this issues.
