Well I think I figured out why my node 28238 can connect. It registers just fine, but it’s not on the status page. BUT. I added this line into my rpt.conf file: 
 
2560 = radio@208.70.77.197:4569/2560,NONE
 
And now it will reliability connect to the WIN system.
 
I also installed an ISP supplied router in place of my D-Link router. That also seems to help.
 
So why doesn't it show up on the status page?  And when I look at connected nodes on 2560, my node is listed but no information is displayed?
 
Thanks
