I am a newbie to networking, so need some help to understand if what I am doing is right:
I have a VM which hosts a Ubuntu guest OS with an internal IP: 192.168.15.6 I have setup an ssh server on port 8002 (in case the ISP blocks 22). I also have a web server (Apache 2) setup on port 8012 (in case the ISP blocks 80).
My external IP is: xx.yy.aa.bb. I have configured my router to port forward port 8002, and now I am able to acces my web server from an external box. But going by the same pattern, I port forwarded my ssh port as:
source ip: xx.yy.aa.bb source netmask: 255.255.255.0 destination ip: 192.168.15.6 destination netmask: 255.255.255.255 (I cannot change this) destination port start: 8002 destination port end: 8002 destination port map: 8002
Why am I not able to telnet into my machine?
