Trusted networks

A trusted network is one that is given access to various NetManager resources such as:

• Access to web-proxy
• Open access to webpages (see "Controlling access to webpages" for more details).
• Sending mail via SMTP
• Ability to update DNS records
• Ability to send network traffic through the firewall

By default, all local networks ranges that are directly configured on the NetManager are trusted (this includes all VPN clients too). The exception to this is if your default gateway is on a separate network to your internal network (i.e. if you are using NAT. In this situation, the gateway network will not be trusted unless explicitly enabled.

The list of trusted networks may need to be altered if your internal network is more complex, for example there is another network range that is not directly configured on the NetManager).

There is an overall list of trusted networks, as well as the ability to configure different trusted networks for different servcices. N.B. Configured trusted networks are in addition to the ones automatically determined from the local configured networks.

In addition, you can configured Untrusted Networks from which access will be denied. This is useful if you only have administrative control to a subnet of the whole network.

The list of trusted networks for services can be configured using webadmin. Currently, the global trusted and untrusted networks must be configured using the trusted_nets and untrusted_nets variables in the NetManager configuration file.
