Dear,
I have the following problem, a customer has a store with two subnets and each subnet had its own public IP.
Graphically
Subnet 1 is not my interest. Subnet 2 is my responsibility.
The problem is that it often loses connection to view the DVR remotely, if I do a portscan remotely, the result is that the ports are closed. When restarting the equipment, the problem is solved.
Subnet 1 has a VPN, and tends to give less problems.
What I can do to avoid this problem?
Router: TP Link TL-WR740N http://www.tp-link.com/en/products/details/?categoryid=241&model=TL-WR740N
Switch 5 port: TP-Link TL-SF1005D http://www.tp-link.com/en/products/details/?categoryid=224&model=TL-SF1005D
DVRs: DMR-1622ARV (16 ch) y DMR-0412NUV (4CH)
Any help here is greatly appreciated
