Thanks Jay.
I was testing few things.
So, I used DigitalOcean’s Discourse marketplace image to create the forum and tested to see everything is working fine.
Then I followed this tutorial - Beginners Guide to Install Discourse on Ubuntu for Development and Importing from vBulletin 4 for DB migration.
Now can I bind port 3000 to listen to the development application that runs vb DB?
If not, any additional steps necessary?
Many thanks,
