Static IP Address in LAN with DVR?

[Seelands]

Hi
I've an Ethernet LAN network without connection to the Internet. The LAN consists of a CCTV-DVR, a D-Link Dir 632 Router and a Laptopcomputer. Now my questions: If the DVR is unplugged or there is a power outage, the router might assign an other IP address to the DVR. I was thinking to assign a static IP address to the DVR. In doing so, do I need to set up only the DVR with a static Ip address or has the D-Link router to be set up with a static IP address (for the DVR) as well? Or will it work with the dynamic IP addresses?

And an other question: If I would need a connection to the Internet, to have remote access, then the router needs to be set for Port Forwarding?

Thanks for advice
Seelands

You can set up the DVR with a static IP without issues - just make sure it's in the same address range as everything else in your network, or you won't be able to see it. Avoid the area where your router assigns DHCP addresses, or you might get an IP conflict.
