Basically, port 80 is blocked, so a redirection from my box wouldn't work..
I've decided to try dyndns as my IP will probably change every so often anyhow (even though it hasn't changed in a week)... Firewall rule is kinda out of ? too becuase its ISP firewall that is blocking port 80,not under my control

...
I think I'll have it working in a few days... dyndns seems to have some nice services for stuff like this
