After all that headache, the one problem I first suggested. The cable was to blame. My boss bought a cable-meter to check the pins, and only 2 of the 4 pairs of cables were actually live. We changed to a new cable and it worked fine. Thanks for the help

Okay, I'm at my wit's end. I have everything configured correctly as far as I know and yet I cannot connect to the DVR even locally, let alone remotely. The DVR's configuration is the following: DVR set to LAN IP: 192.168.1. 149 Gateway: 192.1.68.1. 1 (Router's IP) Subnet Mask: 255.255.255. 0 DNS: (taken from router) Port: 80 I have set up my Router to forward port 80 for 192.168.1. 149. When I try to access my DVR from my computer, it times out. I tried to ping it's IP address and it doesn't work. It is not the network cable because we tried out an IP camera and had no problems connecting to it using the same cable. I had done this same setup before with another DVR of the same make and it was working fine, both local and WAN connection. So I cannot fathom where to START looking for what's wrong. The only info I have on model is SA-KC700. It's I believe a 'generic' Chinese DVR.

Okay, so here's an update on what we've tried. We got it working on the router intermittently, we could see and access it, then suddenly it would stop working. When we tried using the crossover it worked flawlessly and continuously, unlike with the router connection. We do need to port forward because we want WAN access to the DVR, but since we hadn't been able to access it locally (LAN) I needed to concentrate on that first. What would make a network connection work sometimes and other times not? Apparently sometimes it'd start working then stop, then not work at all for an hour no matter how many times we restarted everything, then suddenly once it'd work again.
