Thanks for the prompt response. I shall set up the port forward also and send the images. But another main issue i am facing, port forward or not, when I am trying to use the dynamic dns address to access the pfSense server from within the network, it works and i get the web gui. But it does not happen from an external network (When I say within network, when my laptop is connected to pfsense and pfsense has internet connection. But when I say external nework, my laptop is disconnected from pfsense and I use a usb modem based internet connection on the laptop).
