Figure 80: Interface status detection settings
Detect Server The IP address of the server to test connecting to.
Ping Use standard ICMP ping to confirm that the server is responding. Ping confirms
that the server can respond to an ICMP ping request.
TCP Echo Use TCP echo to confirm that the server is responding. Select this option if the
server is configured to provide TCP echo services. In some cases a server may be
configured to reply to TCP echo requests but not to reply to ICMP pings.
TCP echo uses TCP packets on port number 7 to send a text string to the server
and expect an echo reply back from the server. The echo reply just echos back the
same text to confirm that the server can respond to TCP requests.
FortiGate units do not recognize RST (reset) packets from TCP Echo servers as
normal TCP echo replies. If the FortiGate receives an RST response to a TCP
echo request, the FortiGate unit assumes the server is unreachable.
