FTP timeout : sticky connection issue ?



  • Hey everyone,
    We put in prod firewall pfsense with 2 WAN.
    192.168.52.4 = WAN1
    192.168.53.4 = WAN2
    Sticky connection is enabled.
    Gateway group failover and loadbalancing works like a charm.
    But some users complain timeout when download multiple files from FTP server on WAN.
    I pfTop while downloading a dozen tiny files from one FTP server and I notice that : each time I have a time out, SRC changed. (last line)

    I tried conservative mode + 3600s tracking source timeout but no luck.

    Thanks for your help
