Set Filtering Network Adapter

What to do If failed to filter Internet activity after the setting of Monitoring Port on Cisco Switch?

When it is in the default mode, the network adapter which captures communication data packages will be the same one for sending the blocking packages, however, the user may let system use another network adapter to send blocking packages for controlling the target computer through the setting up of the filtering network adapter.

There will be one circumstance that the user is required to add a special network adapter for filtering. That is, after setting “mirror port” for monitoring data packages, the user might find that the computer can’t communicate with other computers in the same Intranet (suppose that the IP and gateway configuration is correct in the computer), the “mirror port” configured can only receive communication packages, but not be able to send them. It means the “mirror port” is now a single directional one. In this case, we suggest that an additional network adapter be added as appropriative filtering network adapter for iNetWatcher.

The filtering network adapter can be setup in the above 'Advanced'  settings. The user should pay attention that filtering network adapter, mirror port and mirrored port should all be in the same Vlan in the same switching exchanger.
