Hi my geek friends
I used to put my clients IP Phone (of course if it is only one) or ATA in router's DMZ (2wire routers: DMZplus) then I can access them without bothering customers with remote desktop settings or temviewer's anti-commercial use random disconnects.
My problem is some of them work like a charm, no matter from same ISP, US or foreign.
But some of them are stubborn!! I assign static IP to device (ATA or IP Phone) and put it in DMZ (or DMZplus) and when I type recent WAN valid IP of customer's router, nothing happen. No login page for device.
For ATAs I even enable Remote Access too, but no lock
Do you know anything that may help??? Thanks in advance.
