Changing SSH Port Fail To Login In Centos – No route to host

Recently i have been setting up with my own server in Centos playing around with Centos and understanding more about Linux. It has been a challenging and interesting process for me. From a beginner point of view, there is really a lot to learn and explore with hardware. One of this problem i faced was ssh giving me a headache when i change the ssh port to something different rather than port 22.

The whole process of changing SSH port 22 to something else was really to harden the security side for SSH. However, who would have though problem will come for something so simple such as changing SSH port to something else rather than 22?
