Centos 5 ssh problem

[Andromeda05]

Im new to Linux so please bear with me. I'm trying to setup a ssh connection from to my house that way I can learn Linux on a box that won't make my boss the sys admin grind his teeth. He say that ssh port is allowing connections out of the firewall but not in so I can connect to my house. However If I try to connect to my box I get a message stating that the connection has time out. I have port forwarded port 22 to my box and have even changed the port to see if it is my isp blocking me. I am able to connect via SSH internally but when I try outside my house I am running into trouble. I looked up how to disable my fire wall and as far as I know it is.

disable firewall - Howto disable the iptables firewall in Linux

All help is VERY MUCH appreciated

I could be wrong, however i believe that if your work cannot receive packets on port 22 (SSH port) then your Linux box wont be able to send packets back to your PC at work.

I think you'll find that port 22 is only needed to establish an inbound connection.
The ssh server will use the established connection to send/receive data, no need for port 22 on the originating host.

How is your home computer connected to the internet. If it's via a router then you'll have to forward port 22 to your linux box.

I said that I change the port number in order to see if cox my isp was blocking it and I have port forwarded it to the linux box Im just gonna plugg in the box directly to the modem to see if which is the culprate
