Subnet zero is the network address that the routers uses for routing to the
network and the broadcast address sends a broadcast to the entire network
everytime it is used, which means it goes to all subnets. Therefore, these
are not used as host addresses. They encompass the whole network. O

It's probably caused by Netbios packets on ports 137, 138 & 139 ( I'd check
these to make sure), they will cause the router to dial every time it sees
them. You need to set up some IP call filters to prevent them from bringing
up your dial connection. It's normally caused by Microsoft's Client on

Hi, I was reading RFC3022 about Napt last night, and I still dont
understand one thing about it. From what I understand is that Napt allows
you to use one single globally unique IP address on the WAN interface of
your router, and then a large number of local addresses inside your network

You can use 'show processes cpu' to see what process is consuming cpu. The

with standard ping it takes the ip of the outgoing interface as source

hi savvas,
did you try a 'show proc cpu' to identify where the cpu utilization is

To identify who is causing the high packet load you could use logging

No luck with that router. It can only run 10.0 on a good day. If you can
