I have a DLink ADSL modem which I have put into bridge mode and connected to a Fortigate 200A firewall. The Fortigate is able to connect through PPPoE and receives the static public IP. I can browse the internet through the Fortigate with this configuration.
However, the public IP on the Fortigate is not accessible from outside. I cannot ping it and I cannot connect to the Fortigate's admin UI using the ADSL public IP (I have enabled ping and admin access on this wan interface). Any virtual server policies I implement also don't work.
Any ideas on what I'm missing? If you need any additional info please just let me know.
