Personal web server setup problem

[#1]

I am attempting to set up a personal web server on my static IP of 80.229.0.173 without success. I have 2 test boxes running, one with Apache on port 80 and the other with Lighttpd on port 3000. Both are working okay on my internal network. I have set the PlusNet broadband firewall to off. I have forwarded the ports on my router using the "Virtual Server" set-up. Also I tried putting the web servers in DMZ. An external port scan shows that both these ports are open on my static IP however it is not possible to connect. I guess this may be a result of TCP filtering by PlusNet. Am I correct, and will upgrading from Option 1 to Option 2 fix the problem?

I can connect to your IP fine, on both the mentioned ports. I get the "It works!" page, and the "Hi! You got here" page.

You will not be able to connect from inside your LAN, using your external IP address.
I use ; http://www.google.co.uk/language_tools?hl=en to test external connections from inside my LAN, and as a bonus you  get a funny translation of your web site.

Thanks for all your replies - I should have checked properly first!

If you want to use say a domain that points to your internal web server in any URL for testing, then just enter it and the local IP address in your hosts file (in /etc in Linux, windows\system32\drivers\etc in XP).
e.g.
192.168.0.10 domain.com
192.168.0.10 www.domain.com
