PHP Timeout

StefanoColombo

We have the following issue .

Accessing an external web server for an application in PHP which has to create a PDF, from a selection made by the user ,and then provide the link to it , it fails by timing out

If we disable the proxy and the user goes through the firewall it then is successful

the PHP process takes 1 minute to generate the PDF and provide the link

If we make a smaller selection the process takes less and it goes through even with the proxy

 

Is there a way to increase such timeout ?

 

thanks

    Stefano,

    are you using WAF rule to publish PHP webserver?

    Did you find something useful in the logs?

    Thanks

    The Server is published externally by the application provider .

    The logs provided no help since the last line logged is the ...php page which is accepted .

    Stefano,

    check the advanced-parameters from console using the command "show show advanced-firewall" and try to increate the tcp-est-idle-timeout using the command:

    set advanced-firewall tcp-est-idle-timeout "value in seconds"

    Regards

    Here is the current values

            Strict Policy                           : on
            FtpBounce Prevention                    : control
            Tcp Conn. Establishment Idle Timeout    : 10800
            UDP Timeout Stream                      : 60
            Fragmented Traffic Policy               : allow
            Midstream Connection Pickup             : off
            TCP Seq Checking                        : on
            TCP Window Scaling                      : on
            TCP Appropriate Byte Count              : on
            TCP Selective Acknowledgements          : on
            TCP Forward RTO-Recovery[F-RTO]         : off
            TCP TIMESTAMPS                          : off
            Strict ICMP Tracking                    : off
            ICMP Error Message                      : allow
            IPv6 Unknown Extension Header           : deny

     

    the settings of UDP Streams is the only that looks close to the timeout we're experiencing

    Hi StefanoColombo, 

    If you are using a DNAT rule , then you may take a tcpdump of the connection used to recreate this issue. 

    the command to monitor the traffic.

    console >drop 'host <src_ip>

    console>tcpdump 'host <src_ip>

    You may try disabling Strict policy and check if that reduces the delay and may need to toggle and check again.

    console >set advanced-firewall strict-policy off/on

    console> set advanced-firewall tcp-seq-checking off/on
