I have a couple of boxes on my network I've been accessing externally with no problems for years now, but starting on 10/14 I've noticed the connections are being refused. It looks like the ports are being filtered.Nothing has changed with the configuration of the router or the boxes I'm trying to access. They remain accessible from the local network.
Host is up (0.084s latency). PORT STATE SERVICE VERSION 22/tcp filtered ssh 80/tcp filtered http 443/tcp filtered https
