Chapter7. Network Configuration
Physical device
Thistells the physical device name of the network interface. The physical interface eth0 corresponds to Network
Interface1, and eth1 corresponds to Network Interface 2.
Type
Herethe speed options for the interface are shown.
MAC address
TheMAC address of the interface.
Active
Showsif the interface is activated or not.
Link
Hereyou can see if the interface has physical link to the network.
Speed
Hereyou can see the negotiated speed on the interface network.
Duplex
Hereyou can see the negotiated duplex for the interface.
Surroundings
Settingson the Surroundings page are only required when the Telecommuting Module has been made the DMZ
type.
TheTelecommuting Module must know what the networks around it looks like. On this page, you list all networks
whichthe Telecommuting Module should serve and which are not reached through the default gateway of the
firewall.
Allcomputers that can reach each other without having to go through the firewall connected to the Telecommuting
Moduleshould be grouped in one network. When you are finished, there should be one line for each of your
firewall’snetwork connections (not counting the default gateway).
Oneeffect of this is that traffic between two users on different networks, or between one of the listed networks and
anetwork not listed here, is NAT:ed.
Anothereffect is that for connections between two users on the same network, or on networks where neither is
listedin Surroundings, no ports for RTP sessions will be opened, since the Telecommuting Module assumes that
theyare 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
performNAT for any traffic.
