In computing, a stateful firewall is a firewall that keeps track of the state of network connections traveling across it. The firewall is programmed to distinguish legitimate packets for different types of connections. Only packets matching a known active connection will be allowed by the firewall; others will be rejected.

I'd like to know why "for" is used for the verb "distinguish", not "from."
Thank you in advance for your help.

    There are different types of connections.
    Each of these connections has legitimate packets.
    This firewall can distinguish between legitimate packets and inappropriate packets for a variety of connections.

    Does that help?

    The firewall is not distinguishing legitimate packets from different types of connections. Perhaps a better word for "distinguish" would be "identify."
