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.

Just recently installed ntop to do some preliminary testing. Ntop is connected to Cisco Catalyst 2950 switch with port spanning configured to mirror all data to ntop. However, I cannot seem to connect to ntop sensor via web interface. I had verified the installation prior to putting it into the LAN and everything was working fine.
My question is in this configuration, do I need to install a second NIC card in my ntop box? I thought that since all data is being mirrored to the existing NIC, I may need a second card which would then plug into a non-spanned (mirrored) port on the switch which would give me access to the ntop interface. Or is it that I may have simply configured the switch incorrectly?
Thank you.
