MBCDN

Virtuelle Domänen (VDOMs) werden verwendet, um ein FortiGate in zwei oder mehr virtuelle Einheiten zu unterteilen, die unabhängig voneinander funktionieren. VDOMs können separate Sicherheitsrichtlinien und im NAT-Modus völlig separate Konfigurationen für Routing und VPN-Dienste für jedes verbundene Netzwerk bereitstellen. Ähnlich wie Context auf ASA.

Um den Clients Zugriff auf das Internet zu geben kann man eine einfache Firewall Policy erstellen und dabei den Haken bei NAT (als Adresse das Interface) setzen.

config firewall policy
    edit 1
        set name "INTERNET ACCESS"
        set srcintf "port2"
        set dstintf "port1"
        set srcaddr "LOCALSUBNET"
        set dstaddr "all"
        set action accept
        set schedule "always"
        set service "ALL"
        set nat enable
    next
end

Um einen Server zu exposen erstellt man eine virtuelle IP und eine Firewall Policy (WAN → LAN) dazu. (Bei der Firewall Policy nicht die IP selbst angeben oder als Objekt erstellen sondern das Objekt der virtuellen IP verlinken).

config firewall policy
    edit 4
        set name "test"
        set srcintf "port1"
        set dstintf "port2"
        set srcaddr "all"
        set dstaddr "server"
        set action accept
        set schedule "always"
        set service "ALL"
    next
end

config system gre-tunnel
    edit "GRE-Tunnel"
        set interface "port1"
        set local-gw 100.0.0.2
        set remote-gw 200.0.0.2
    next
end

# Alternativ (untested)
config system interface
    edit "GRE-Tunnel"
        set vdom "root"
        set ip 192.168.0.2 255.255.255.255 # muss /32 sein!
        set allowaccess ping
        set type tunnel
        set remote-ip 192.168.0.1 255.255.255.0 
        set interface "port1" # Lokaler Tunnel Endpoint
    next
end

Auth via User/Pass oder API Token.

API Admin erstellen; System → Administrators → new with API key

curl -k -L "https://10.5.1.1/api/v2/my/path?access_token=xxxxxxxxx"

In Postman die Auth auf „API Key“ stellen.

• Key: access_token
• Value: API-Token
• Add-to: Header
