Fun facts you discover on the road: I noticed that when connecting from some corporate nets, I would lose connectivity back to my own kit at random intervals, with a "no route to host" status.

It turned out that the little cron job I had on my server end that blackholed no hostname mailers was the culprit.

Somehere in these nets, somebot was NATed to the same routable IP I was using. #NAT #blackhole #PF #openbsd #nohostname #reversedns
