    Likely. Take a look-see at src/sbbs3/websrvr.c and have at it! :-)

    digital man

    I need return to this topic,


    my log still show that connection from proxy as 127.0.0.1

    Dec 25 20:27:08 scarlet synchronet: web 0086 HTTP Logon (user #2)
    Dec 25 20:27:08 scarlet synchronet: web 0090 HTTP connection accepted
    from: 127.0.0.1 port 57490


    Then, i cannot get my fail2ban working optimal for block the source ip
    address because, it's get 127.0.0.1 instead of the real:


    synchronet: web 0031 HTTP Throttling suspicious connection from:
    127.0.0.1 (5 login attempts)
    Dec 25 06:27:17 scarlet synchronet: web 0087 HTTP connection accepted
    from: 127.0.0.1 port 49286

    Could someone else who uses nginx in front of sbbs confirm what address appears in the log?

    thanks!
