Steve,
You will have to put on an ingress filter to allow your outside traffic to
get to the ntop server. I have 2 vlans on a cisco 3560, one for the
customer. Vlan 40 is the link to our data center, and 41 the user link.
Below are the commands that I use.
monitor session 11 source interface Fa0/1
monitor session 11 destination interface fa0/12 ingress untagged vlan 40
This allows me to access the ntop server.
