Thanks @Keith_Beddoe. I had already realized how to do all the cabling part (a real IT literate should figure it out quite quickly IMO). I have even put my own firewall in DMZ. Still no luck in accessing all the ports. If I run an NMAP from the outside to my public ip address, the open ports that are open on my firewall results being closed during the scan.
Hence my necessity to turn off the firewall of the BT Hub. Thanks!
I know this thread is a little old, but for those of you who haven't figured it out, and landed here while searching (like me), here's a way to disable the firewall:
Right click on the Disabled radio button and choose Inspect.
In the element pane, right click this line:
<input type="radio" name="Security" value="2" id="rdbbasicSecurity2" lang="1" disabled="" class="ori_radio" style="margin: 4px 5px 0px 0px;">
choose Edit as HTML and remove:
Now the button is fuctional again, select it and click Apply.
Sounds about right. If people are knowledgeable to think about firewall disabling - then perhaps they ought to get their own hub/router
Gee guys, instead of mucking around with an unconfigurable hub and then saying 'It doesn't work' just buy a proper router and you can do whatever you want with it.
