LAN Scanning tool causes network disruption #20
Description
When using a network scanning tool to scan the LAN for network devices, the scan drops and ICMP drops as well to the routers. This is happ0ening for both AMD and ARM.
Tested using Advanced IP Scanner.
- Start ICMP ping to routers and verify no drops
- Start scanning with AIS tool to advertised LAN subnet
- Watched ICMP drops and scan fail
- Strop scan and the ICMP comes back after several seconds
This is happening for all my routers on different networks and both architectures so I know its package related. All other network services seem to work just fine. Its when the LAN is scanned that havoc begins.
