2. Select Advanced settings and highlight Inbound Rules in the left pane.
3. Right click Inbound Rules and select New Rule.
4. Add the port you need to open and click Next.
5. Add the protocol (TCP) and the port number (8085) into the next window and click Next.
6. Select Allow the connection in the next window and hit Next.
7. Select the network type as you see fit and click Next.
8. Name the rule and click Finish.

To open port with firewalld (Linux):

sudo firewall-cmd --permanent --add-port=8085/tcp
sudo firewall-cmd --reload
