Now to be fair, I've done most of it but there is just 1 thing I'm struggling with.
I have a WHS2011 box that runs 2 websites.
When I was on ADSL using a TP-Link TD-W8970, I could access the 2 websites using their external address but from within the LAN. It was a handy way of me being able to check that the connectivity was OK.
Since going to fibre, I now have a HG659, and I have set up all the same port forwarding rules as I had before.
Now I cannot access the websites from within the LAN. It works using their internal address and I am mostly sure that they can be accessed from outside the LAN.
What other setting do I need to adjust to be able to access my websites via their external address but from behind my router?
