Own ASN and IPv4 / IPv6 Prefixes Configuration

Dear All,

Currently we are using the IP addresses our ISP gave us to surf the Internet with a few other public IP addresses for some of our internal services. However, we have just got assigned our very own IPv4 and IPv6 public addresses (prefixes) and ASN so we can have the same public IP addresses no matter the ISP we use.

In this case, how can I configure these new addresses and the new ASN into the Fortigate unit so my ISP understands I have my own public IP addresses and ASN? Moreover, how can I configure a second WAN interface for a second ISP in case I need WAN redundancy?

Thanks a lot for your help as your comments are really appreciated.

Kindest Regards,

Elkin D.
