OK, so this isn't really for me, it's for my boss. I believe he may be deranged, he wants to see the cameras on the DVR from his Iphone.
I started with ports on the DVR, it wants to use port 3000.
They use a Linksys Firewall, so I put in a rule that said something along the lines of "if you hit the WAN interface of this firewall with port 3000, forward it to 192.168.2.100" which is the IP of the DVR.
I have the username and password correct, but I get a timeout error trying to login (using Pegaso Lite).
My DVR has entries for DynDNS and such, but I can't see how that would work since the DVR is behind the NAT firewall.
Hope to hear some suggestions!
