This is usually an ISP issue.  Happens to me all the time with my crummy cable ISP.  Usually have to restart the cable modem and router to get it playing nice again.  DMZ or not, your router or the remote router could be blocking traffic.  I’ve seen it a 100 times here though your issue could be different, my two cents.

Subject: [App_rpt-users] What is wrong with my node?

Why is this happening? See below.....   The internet is working just fine from the site. I logged into the node and the router remotely at the moment. The node repeater is in the DMZ. I can ping google.com so the DNS is working.

This node not being able to re-connect or connect is really not cool!

What is going on here?

Thanks!
