Download CCcam on both boxes, the box with the card in goto menu/expet setup/communications setup and tick the DHCP box press the green button to save exit all then reboot, once its rebooted go back to menu/expert setup/communications setup, this will give you your correct IP.
IP 192.168.0 ?
Netmask 255.255.255.0
Type LAN
Nameserver & Gateway shoud be the same 192.168.0.1
Tick enable network
Port 80
if it all looks like that then your network should be fine.
Once you have downloaded CCcam you need to put an F: line in the box with the card, and the other box will need a C: line in cccam.cfg file.
I am unsure if we are supposed to be talking about this subject, if this is the case sorry in advance.
If its ok to talk about this subject and you get stuck, put on another post and i'll get back to you with the config files.
