Hi guys, i just want to ask something
I’ve been install SNMP Plugin in graylog then i test with snmpwalk, but i cannot recieve message in Graylog Web Interface.
This is my configuration :

This is my WLC SNMP port and SNMP Trap Port :
163 for SNMP TRAP 161 For SNMP Port

Then i’m add my gralog to communities and TRAP Reciever in my WLC
And this is my Input Configuration

i’ve been redirect port 163 to port 1630 in my graylog server this it the iptables
root@graylog-server:/home/user# iptables -t nat -L -n -v --line-numbers
Chain PREROUTING (policy ACCEPT 4 packets, 1027 bytes)
num pkts bytes target prot opt in out source destination
1 0 0 REDIRECT udp – eth1 * 0.0.0.0/0 0.0.0.0/0 udp dpt:163 redir ports 1630

But i cannot recieve any message from that :

snmpwalk is for query, not for SEND snmp traps.
it’s two different things

send an SNMP trap instead of query a reciever port.
