To improve your interactive job performance, you may want to consider using VNC, as described in the article below.
There are, however, times were your IT team may be blocking the required outbound TCP ports from your network. Should you choose to use VNC, please check with your IT team, and ensure they're allowing TCP port 5900 and 5901. Additionally, when your IT team is allowing these TCP ports out of your network, they may also want to know what the source network is, which is 220.127.116.11/23.
Let us know if you have any additional questions on how to leverage VCN to improve your remote, interactive based sessions.
