You need putty for this.
Next, go to your IPCOP web configuration page. System-> SSH Access-> Tick the SSH checkbock.
Click save. That's it, you're done. Now you can access IPCOP from your putty by entering IPCOP's GREEN interface (if you're inside your LAN). Remeber to use port 222 instead 22! This can be done within putty GUI, you can see text box beside IP destination. That's where you put port 222.
