Hosting Website - DNS Rebinding Attack

[dizydiz]

Hi,
  I have pfSense 2 up and running and port 80 inbound redirected to my IIS box via NAT. This works fine from external. However when I am internal and I try to brows my hosted website on IIS, I get "Potential DNS Rebind attack detected" message.

How can I fix this so I can brows my internal websites, while being on the internal network?

Thx,

DizyDiz
