Fortigate virtaul IP and port forwarding
Usually we use VIP to implement Destination Address Translation. Mapping a specific IP address to another specific IP address is usually referred to as Destination NAT. When the Central NAT Table is not used, FortiOS calls this a Virtual IP Address (VIP).
Why virutal IPs and port forwarding in fortigate firewall
With the help of virtaul IP and port forwarding outside users I mean public users can acccess our servers which is installed behind a firewall, without knowing the server’s internal IP address and only through chosen ports.
