R7800 internet crashes with nmap scan

When I am attempting to scan a target outside of my network over the Internet and use the nmap scanning tool my router drops the Internet connection.


R7800 with firmware (latest as of 4/8/2020).


nmap -n -p- TargetHere

When I log into the web interface of the router it shows the Internet as (disconnected).  If I try to manually release and renew the connection it eventually gets an IP again, but the network is still non-functional until I cancel the nmap scan.


Machine on my network running the scan is directly connected via Ethernet to the router which uplinks to my ISPs ONT.


Other devices lose their Internet connection as well, but local LAN and WiFi to local NAS devices still function.



Anyone else see a problem like this one?
