Blocking snmp

  • I was curious is it possible to block SNMP outbound on a specific client ?

    A bit more info.
    Theres a spammer on my friends network (A total of a few hundred hosts), He's running pfsense, Im sure I can find the spammer with tcpdump.

    I don't have access to the box right now or I probably would have figured this out by now.

  • SMTP I assume then (Simple Mail Transfer Protocol)?

    If you can identify them by IP then just create a firewall rule blocking access to 25/TCP for those IPs.
