I build a LAMP server behind a router.
The current situation is:
1.I could access index.html of apache within the LAN.
2.I could access the vsftp outside of the LAN.
3.I could access the ssh outside of the LAN.

I have configured my router to do reflections(although I don't know it's correct or not.). I think the LAMP works good since I could use it inside the LAN. The configuration of the router is at least partly right because ssh and vsftp work fine(I test by browsing the ip:74.***.***.*** in the lan, not 192.168.1.8 --this also works. ).

I cannot access web service outside the LAN. And the error message is "Oops! Google Chrome could not connect to 74.***.***.***"

Did I miss some configuration of router?Apache2?Ubuntu? I use the ubuntu server 2010.10 version.

Really appreciate who is concerning on this problem.

In your router, make sure you've forwarded port 80 to your LAMP server's IP address. If you're sure you've already done that, then I suspect your ISP is blocking port 80 inbound. Mine does. You can check if this is the case by designating a different listen port on the Apache server and then forward to that port.
