Steve, Problem solved!! i am using NOIP.COM to direct traffic to the public of my router and then on to my Allstar Node as well as my DVSWITCH server. The only time I have an issue is when I am at home and do this using USRP for digital contacts on DMR. So if at home I now use the DVSWITCH Lan IP address and all is good. When away from I use my service provider cell hotspot and all is well.
There others in our group that don't have the issue but they are using different routers. Mine is a Netgear.
Thanks for your help. The divide and conquer routine did its job.
