Chapter 7. Network Configuration
Physical device
This tells the physical device name of the network interface. The physical interface eth0 corresponds to Network
Interface 1, and eth1 corresponds to Network Interface 2.
Type
Here the speed options for the interface are shown.
MAC address
The MAC address of the interface.
Active
Shows if the interface is activated or not.
Link
Here you can see if the interface has physical link to the network.
Speed
Here you can see the negotiated speed on the interface network.
Duplex
Here you can see the negotiated duplex for the interface.
Surroundings
Settings on the Surroundings page are only required when the Telecommuting Module has been made the DMZ
type.
The Telecommuting Module must know what the networks around it looks like. On this page, you list all networks
which the Telecommuting Module should serve and which are not reached through the default gateway of the
firewall.
All computers that can reach each other without having to go through the firewall connected to the Telecommuting
Module should be grouped in one network. When you are finished, there should be one line for each of your
firewall’s network connections (not counting the default gateway).
One effect of this is that traffic between two users on different networks, or between one of the listed networks and
a network not listed here, is NAT:ed.
Another effect is that for connections between two users on the same network, or on networks where neither is
listed in Surroundings, no ports for RTP sessions will be opened, since the Telecommuting Module assumes that
they are both on the same side of the firewall.
Normally, at least one network should be listed here. If no networks are listed, the Telecommuting Module will not
perform NAT for any traffic.
