I did some archive digging and it was shorewall that got me on this.  
And then I went into conservative mode, as this impacted my firewall on 
Centos.  Obviously overly conservative.

I am learning more, and this time, for example, I am trying hard NOT to 
edit http.conf, instead to put some http.d/00-init-nn.conf files 
together so I can know as much as possible what I have added.  I don't 
know yet if that can be done.  I have done this on my test mail server.  
Will see if I can do it on my web server.
