plz tell why when i scan a few ip ranges does masscan kill my internet connection... i even dropped the rate to 1000 is there any special settings or am i doing something wrong - am using kali linux 2022 your help is appreciated

Got the same problem but with windows. It doesn't just drop the Internet-connection, it crashes the Fritz box on Windows (when having rate more than 4000).

I tried it on several Computers with fritzboxes and different ETH/WIFI Adapters.

It must be a bug with masscan and winpcap. Same drop doesn't happen using Linux.

Can confirm, but I think this is a bug in FritzBox, not in masscan.

I can reproducably crash my fritzbox with latest firmware by running

masscan 192.168.0.0/16 -p80 --banners -oG scan.txt --rate 100000 --adapter-ip 192.168.178.254

from a linux-PC.

I'll try to contact avm support now.
