Hi,
I require clarification on the ports required to be opened for NET-SNMP to work. I know that UDP 161 is required, but I have been unable to confirm if this needs to be opened as a 2 way rule as shown below: Source Destination Port Monitoring Server Monitored Server UDP 161 Monitored Server Monitoring Server UDP 161 Or a 1 way rule as shown below: Source Destination Port Monitoring Server Monitored Server UDP 161 I have checked the FAQ and archived messages and have been unable to find this information. I managed to find the following info (Link <http://www.net-snmp.org/wiki/index.php/FAQ:General_18> ), but it doesn't quite clarify the question for me: What ports does SNMP use? There are three main network ports (and one named socket), which are typically used by SNMP. These are: UDP port 161 - SNMP requests (GET* and SET) UDP port 162 - SNMP notifications (Traps/Informs) TCP port 705 - AgentX /var/agentx/master - AgentX We don't use SNMP Traps and I am not aware of what AgentX is, we use Solarwinds as our monitoring server and NET-SNMP as the SNMPv3 agent for all servers within our DMZ.
