That probe uses the Net::SNMP module to manage SNMP queries. IIRC,
Net::SNMP defaults to using UDP, however it will switch to TCP if it
can't reach the host via UDP.<br>
<br>
Can you confirm whether you can reach the router with UDP from the
server hosting Smokeping by using other SNMP tools (e.g. snmpwalk, etc)?<br>
