NAT / VIP - Port forward

Lav VIPs for hver port der skal åbnes/forwardes, fx:

public.y.xxx.zz --> 192.168.1.50 (TCP: 3390 --> 3389)

Hvis der er flere porte mod samme server, kan der laves en VIP group.

Herefter er det bare at lave en policy med VIP group som destination og ALL i Service.

Session helper

http://help.fortinet.com/fos50hlp/52data/Content/FortiOS/fortigate-system-administration-52/Session%20Helpers/session_helpers.htm

The FTP session helper monitors PORT, PASV and 227 commands and NATs the IP addresses and port numbers in the body of the FTP packets and opens ports on the FortiGate unit as required. To accept FTP sessions you must add a security policy with service set to any or to the FTP, FTP_Put, and FTP_GET pre-defined services (which all listen on TCP port 21).

Husk at ændre port hvis du kører FTP på andet end port 21:

config system session-helper
edit 1
set name ftp
set port 21
set protocol 6
next

Layer-2 VPN with VxLAN over IPsec - Extend LAN over IPsec

Technical Note: Building a Layer-2 VPN with VxLAN over IPsec

VXLAN Encapsulation in FortiGate

Notes: Husk det er L2, så IP opsætning er ikke nødvendigt på interfaces/soft switch. Men hvis den ene side skal have IP, hvis man fx vil udvide LAN over IPsec, så skal IP sættes på soft switchen, og ikke det fysiske interface. Og kun på den ene side af tunnelen.

Fortigate 1:

config vpn ipsec phase1-interface
    edit "VXLAN-IPSec-VPN"
        set interface "wan"
        set peertype any
        set proposal aes128-sha1

    next

config vpn ipsec phase2-interface
    edit "VXLAN-IPSec-VPN"

        set proposal aes128-sha1
    next
end

config system switch-interface
    edit "soft_switch"
        set member "port2" "VXLAN-IPSec-VPN"
        set intra-switch-policy explicit   // (optional)
    next
end


config firewall policy //Hvis du har brugt intra-switch-policy explicit på switch.

config system interface //Hvis det lokale interface skal have IP opsætning, så sættes IP indstilling på switchen i stedet for interface.
    edit "soft_switch"

FortiClient

Gratis VPN klient og antivirus.

Vulnerability Scan: Holde programmer opdateret. Manuelt via Fix Now knappen.

Enforce FortiClient Compliance Check kræver man har 100% styr på alle devices der kræver internet forbindelse på netværket.

Når så Enforce FortiClient Compliance Check er sat til, kan FortiClient hente indstillinger fra Fortigate, fx Web filter, men man skal selv trykke Fix non-compliant Settings knappen for at rette indstillinger så de passer med dem fra Fortigate.

En work around kan være at exempt hele lan netværket.

Fix non-compliant Settings kommer ikke frem hvis ikke Enforce FortiClient Compliance Check er sat til.
