Re: snmptrapd doesn't log SNMP trap messages
also with option snmptrapd -d, I can't see anything. But I can receive the messages with tcpdump. Can it be a firewall problem?

Re: snmptrapd doesn't log SNMP trap messages
We don't change any packages on the firewall with iptables. And the SNMP traps reach the destination host, because I see them with tcpdump. It this not an indication, that the firewall let pass the packets?
