When I go to iknowwhatyoudownload.com, a bunch of stuff shows up for my IP that’s definitely not being downloaded by anyone in my house (foreign language torrents). Aside from that my router (AT&T Arris BGW210) needs to be restarted about once a week, due to some kind of dhcp issue. The most recent event seemed bad - none of my devices had internet, they could all talk to each other, and my ONT activity light was flickering steadily. During this time I had no access to the router, even plugged in directly to LAN. Fixed by a restart but no idea what was going on.
The DHT torrent thing has been happening for months and the router thing could just be that AT&T sucks. I have no other evidence that something is wrong.
I could buy a firewall and put it downstream of the AT&T equipment.
I could switch internet providers, get a new IP address and router, and see if that fixes it.
Should I try to figure out what’s going on or just keep restarting the router once a week and ignore the DHT hits from my static IP?
There isn’t really a good reason to not be doing that already just because of the intrusion detection systems Proxmox has to offer. Most of them would alert you immediately if you were compromised told it to look for DHT broadcasts going out of the network.
