Hi - I’ve received multiple emails to say that a device on my network has a potential SNMP vulnerability, and I need to find out why. Wondering whether this could be caused by having a VPN on one of our devices, which allows files to be shared with someone abroad?
If you have questions about the setup and configuration of your network, you'll be more likely to get useful answers in the 'Networking and WiFi' forum where there are a lot of networking experts who might be able to advise
It is unlikely use of a VPN triggered the SNMP vulnerability notice.
If you are unable to scan your public IP Address using the snmpget (or similar) command, see Open SNMP Report, then either review the security of devices that provide SNMP service within your home network (for example network attached storage, network printer, etc.) or use Hub's port forward feature to block such scans, see mDNS and SSDP vulnerabilities a suggestion for devices in the DMZ — for SNMP forward port 161 UDP
