    I have a linux server with services and an iptables configuration set to
    discard any NEW incoming packets that aren't for these services.  I do
    this based on protocol and port.  (e.g. Accept: TCP/80, TCP/21)
    
    I want to add a SOCKS5 server (Dante) to the list of services.  The
    problem with this is that this server can listen to any arbitary port
    above 1024 for port tunneling, but I don't want to automatically allow
    all ports > 1024 in iptables.
    
    I'm wondering if there is a way for iptables to determine which ports
    are in use by the SOCKS5 server and selectively allow those.


You can allow related packets.
