Blocking snmp
« on: March 02, 2009, 05:18:14 pm »
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.
If you're planning on PMing me to ask me to look at a thread, or for individual support, don't.
