Interfaces

Network

The Network tree menu allows you to configure device interfaces, DNS configuration, static routing, and packet capturing.

Interfaces

To view the interface list, go to System > Network > Interfaces.

The following information is shown:

Edit Select to edit the selected interface.
Search Enter a search term in the search text box then select Search to search the interface list.
Interface The names of the physical interfaces on your FortiAuthenticator unit. The name, including number, of a physical interface depends on the model.
IPv4 The IPv4 address of the interface.
IPv6 The IPv6 address of the interface, if applicable.
Link status The link status of the interface.
To edit an interface:
  1. In the interfaces list, select the interface you need to edit and select the Edit button, or select the interface name. The Edit Network Interface window opens.
  2. Edit the following settings as required.
    Interface The interface name is displayed.

    Status

    The interface's current link status is displayed.

    IP Address / Netmask
    IPv4 Enter the IPv4 address and netmask associated with this interface.
    IPv6 Enter the IPv6 address associated with this interface.
    Access Rights
    Admin access

    Select the allowed administrative service protocols from: Telnet, SSH, HTTPS, HTTP (GUI), and SNMP.

    When HTTPS is enabled, you can also specify GUI (/login), REST API (/api), and/or Fabric (/api/vi/fabric) access.

    Services

    Select the allowed services from: HTTPS, HTTP, RADIUS Auth, LDAP, LDAPS, FortiGate FSSO, OCSP, FortiClient FSSO, Hierarchical FSSO, DC/TS Agent FSSO, Syslog, RADIUS Accounting SSO, and/or RADIUS Accounting Monitor.

    When HTTPS is enabled, you can also specify Self-service Portal (/login), Guest Portals (/guests), SAML IdP (/saml-idp), SAML SP SSO (/saml-sp, /login/saml-auth), Kerberos SSO (/login/kerb-auth), SCEP (/cert/scep), CRL Downloads (/cert/crl), FortiToken Mobile API (/api/v1/pushauthresp, /api/v1/transfertoken), and/or OAuth Service API (/api/v1/oauth) access.

    When HTTP is enabled, you can also specify SCEP (/cert/scep) and/or CRL Downloads (/cert/crl/) access.

    Note that Syslog is only available if Syslog SSO has been enabled. See General settings for more information.

  3. Select OK to apply the edits to the network interface.

DNS

To configure DNS settings, go to System > Network > DNS.

The following settings can be configured:

Secondary DNS server The IP address of the secondary DNS server.
Enable DNS cache Enable to cache the responses to DNS queries.
DNS cache maximum TTL When DNS cache is enabled, configure the length of time in seconds responses to DNS queries are cached. If the configured value is larger than the time to live (TTL) value specified in the DNS record, the DNS TTL value is used. The default is set to 0, which uses the TTL value specified in the DNS record.

To apply changes, select OK.

Static routing

To view the list of static routes, go to System > Network > Static Routing. Routes can be created, edited, and deleted as required. Use the checkboxes to select the static route entries you want to either Delete or Edit.

  3. Select OK to create the new static route.

Packet capture

Packets can be captured on configured interfaces by going to System > Network > Packet Capture.

The following information is available:

Edit Select to edit the packet sniffer on the selected interface.
interface The name of the configured interface for which packets can be captured.
For information on configuring an interface, see Interfaces.
Maximum packets to capture The maximum number of packets that can be captured on a sniffer.
Status The status of the packet capture process. Allows you to start and stop the capturing process, and download the most recently captured packets.

To start capturing packets on an interface, select the Start capturing button in the Status column for that interface. The Status changes to Capturing, and the Stop capturing and download buttons become available.

To download captured packets:
  1. Select the download button for the interface whose captured packets you are downloading.
  2. If no packets have been captured for that interface, select the Start capturing button.

  3. When prompted, save the packet file (sniffer_[interface].pcap) to your management computer.
  4. The file can then be opened using packet analyzer software.

To edit a packet sniffer:
  1. Select the interface whose packet capture settings you need to configure by either selecting the configured interface name from the interface list, or selecting the checkbox in the interface row and selecting Edit from the toolbar.
  2. The Edit Packet Sniffer page opens.

  3. Configure the following options:
    interface The interface name (non-changeable).
    Max packets to capture Enter the maximum number of packets to capture, between 1-10000. The default is 500 packets.
    Include IPv6 packets Select to include IPv6 packets when capturing packets.
    Include non-IP packets Select to include non-IP packets when capturing packets.
  4. Select OK to apply your changes.
