You need to open udp/161/snmp) from your Orion-server to all your devices, and udp/162(snmp-trap) from your devices to your Orion-server.

Then you also need to open for icmp in both directions.

For the toolset to work you need to open tcp/23(telnet) and/or tcp/22(ssh) from Orion-server to your devices.

thank you for your reply.

i opened the ports 161 and 162, but it is not working.the icmp is working well, it seems like the orion using differnt ports for snmp , and also the toolset- for every toll it is a different port.

the orion and the toolset are installed on the server that has ghost all firewall.

it is look like it is using other ports...like 4664 for gauge, 135,445,1053 and a lot more... is there a list of the ports i need to open ?

SNMP is standard UDP161 (Read) and UDP162 (Trap). You rules should be :

permit udp <your orion server> <your devices being polled> eq snmp

That works for a stateful firewall....ACLs are a different story if you use a router. You need to create the reserse permit.
