Multi-NIC configuration in RiskFilter
You can use Webmin to set up a multi NIC environment. Once this is done, both IPs can be used to access
the System Management console, the Management Console, the MTA and all other services. The
following scenarios are possible.
RiskFilter between two networks. You can set up RiskFilter between two networks, for example between
the user network and the DMZ (Demilitarized: Zone):
Figure 5 - 10 RiskFilter between two networks
• Network 1 – A network in which clients send e-mail to RiskFilter. This network could be blocked for
access to the System Management Console and the Management Console via a firewall. This is
connected to the eth0 NIC.
• Network 2 – The network where the internal servers lie. This network holds the mail servers and
RiskFilter administration clients. This is connected to the eth1 NIC.
• RiskFilter – Your RiskFilter appliance comes with eth0 configured. You set up the second NIC (eth1 in
the above example) as follows.
