One thing I notice is that the addy 192.168.0.1 is very likely your router, not the
computer you are using. The computer addy should be somewhere between
192.168.0.100 to 192.168.0.199. It works best for me BTW, to assign a static addy
in my router to the computer HFS is on. Othewise the router will reassign one sometimes.
The 202.137.112.7 sounds more like your IP. There should be a page in your router config.
that shows you the external IP address assigned to you by your ISP ?
I'd turn off the remote administration, and reassign a port in HFS. Try something like
9xx, then after checking that this is not assigned by the router to something else,
port forward private port, say 901 and public port 901. Turn off all firewalls and try
self test. If it works, it should work from anywhere.
