I have a router Cisco 2811 and I am trying to configure one Fastethernet interface, but I have some problems and don't know how to solve them.
I configure this interface like a LAN one and I connect a PC with a IP of the same subnet but the lights don't light and the protocol is down.
This is the configuration:
ip address 192.168.4.1 255.255.255.0
ip nat inside
ip nat inside source list 102 interface FastEthernet0/0 overload
access-list 102 permit ip 192.168.4.0 0.0.0.255 any
This is the output of command : 'show interface fastethernet0/1':
FastEthernet0/1 is up, line protocol is down
Hardware is MV96340 Ethernet, address is 0024.14eb.8bb9 (bia 0024.14eb.8bb9)

I've tried this configuration in other routers and it worked so I think the interface can be damaged .The router is a new one. I've tried the same configuration in the other interface and it worked with the same cable and PC.
I also have problems to connect via consola, because I can connect one time when I the router start up, but next times I can't see anything on the hyperterminal screen.
Anybody can help me to know if the interface is damaged and what is wrong with the consola?
When I first read your post I thought that the issue was that when you connect the PC to the router that you use a straight through cable. When connecting a PC directly to the router interface you need a cross over cable.
I see that your post says that you have used this same PC and cable to connect to the other interface. Can you give us some details about this?
I am connecting the PC correctly. The other interface Fa0/0 is configured like a WAN interface and connected to another cable and it is working properly because I have connectivity from this interface.
Do you know any command to test the problem?
Thanks a lot
I've been looking for the IOS the router needs, and I've founded that is needed version 12.4(9)T, so I think it's not necessary to upgrade.
Any other ideas?? I don't know what to do.
Thanks a lot
I've configured in the router:
It works like this with the same configuration, cable and PC with the other interface F0/0.
