cisco 878 and 3com how to get it working and getting access to IP camera via public IP
I am making an assumption here, as you have not put in your exact config, that the subnet mask for your LAN segment is a /24 (255.255.255.0). Be aware that you cannot NAT to port 80 on the IP address 192.168.0.0 as it is the network address and as such unusable as a host address. [...]

What happened if I set ip unnumbered fa0/0 in my serial interface and later my fa0/0 went down?
If you use “ip unnumbered fas0/0″ on your serial interface and your fas0/0 interface goes down then any packets destined for the that IP address will not be processed and OSPF will drop. The packets are not processed by the interface per say, they arrive on the interface and then they are actually processed by [...]

Cisco 3560 port shutting down
There are lots of reason why IOS will shutdown an interface but basically it is due to the software detecting an error condition. It could be that a cable is out of specification (either too long, the wrong type, or defective).
