I’ve seen normal Ethernet cables last 10+ years outside without issue.

Northern New England here, have had a UTP Cat 6 cable running from my house to the shed for about 5 years, I didn’t even bury it. Not suggesting its the right way to do it, but it works fine. I do network installs all day, last thing I feel like doing at home is work :p

I block all RU and CN ip addresses. No ill consequences.

Netstat shows locally established/awaiting connections to the LAN and WAN. Traceroute is a completely different utility that shows a path traffic takes to get out to a specific address. You are wrong.

The one thing that almost makes sense in your incoherent comment is that the gateway device (typically an isp supplied modem/router) identified from a tracert command is that which an engineer could potentially observe internal clients’ traffic on.

Found the Indian tech support scammer :p
