NMAP Scan see SNMP UDP 161

Hi there

I ran a internet scan against WAN side of multiple sites with RV5X running 14.7.1 and see UDP 161 (SNMP) port open. I thought these RV5X doesn’t expose SNMP on WAN side, but only on LAN side. How do I make sure SNMP is only seen on LAN and not on WAN for security reasons.

Thanks

Hi @ahong,

Can you answer the questions below to analyze this issue:

  • When you ran an internet scan against the WAN side, among the RV50X you scan, are there any running 14.7.1 that don’t see UDP 161 (SNMP) port? If you have, please send me full log.
  • When you ran an internet scan against the WAN side, have you tried scanning RV50X running firmware other than 14.7.1? If so, can you see the UDP 161 (SNMP) port open? If you have, please send me the full log.
  • Please send me the screenshot and full log when you configure SNMP on RV50X to investigate the issue.

Thanks,
