Technical Tip: TCP/7810 port open when WANOpt is not enabled

TCP 7810 is used for WANopt. It has been identified while doing a vulnerability scan that TCP port 7810 is open and listening when WANOpt is not enabled.

config system interface
    edit "port2"
        set vdom "root"
        set ip 10.193.3.141 255.255.240.0
        set allowaccess ping https ssh http telnet
        set type physical
        set snmp-index 2
    next
 end

• When using telnet to port 7810 on 10.193.3.200, a TCP handshake can be observed on that port, indicating that the port is open and actively listening for connection.

The resolution for the identified issue, referenced as known issue 1070236, has been addressed and fixed. The solution for it is to upgrade to FortiProxy 7.0.19, FortiProxy 7.2.12, FortiProxy 7.4.6 and FortiProxy 7.6.0.
