I’ve got one, I’m afraid. I can’t see what they are doing — only a number of rejected probes, then my edge router crashes and reboots, with no supout. I’ve gone through the firewall and can’t see any holes. The only respite I get is blocking the Chinanet block involved, until a couple days later when they come at me from another block. I’ve considered blocking all of them, but the list is huge and I don’t want to swamp my 493G.
