+# Network Tunnel Card
+![Tunnel vision?](item:oc2:network_tunnel_card)
+
+The network tunnel card allows [computers](../block/computer.md) to send messages to and receive messages from another tunnel device (tunnel cards and [tunnel modules](network_tunnel_module.md)) linked to the card.
+
+Computers *have to be shut down* before installing or removing this component. Installing it while the computer is running will have no effect, removing it may lead to system errors.
+
+To link two tunnel devices, open their configuration interface (use while holding), and insert the other tunnel device to link to. This allows linking any two network tunnel devices.
+
+When using the default Linux distribution, this device will provide a regular ethernet device. Network setup can either be performed manually, or using the convenience script `setup-network.lua`. This script provides the option to either use a fixed-address setup, or a DHCP setup. For a DHCP setup, exactly one computer in the network must act as a DHCP server.
+
+After initial setup, use the command `ifconfig` to see the currently used IP address.

+
+When using the default Linux distribution, this device will provide a regular ethernet device. Network setup can either be performed manually, or using the convenience script `setup-network.lua`. This script provides the option to either use a fixed-address setup, or a DHCP setup. For a DHCP setup, exactly one computer in the network must act as a DHCP server.
+
+After initial setup, use the command `ifconfig` to see the currently used IP address.
