Creates TUNTAP interface and translates traffic to PDUs. See TUN/TAP for an explanation of the functions.

When the TUN option is chosen, a virtual ethernet interface is allocated to the specified Interface name (tun). It's IP address can then be set by:

sudo ifconfig tun 192.168.200.1

GNU Radio needs root privileges to use this block.

Note for 3.10 This block has been moved from gr-blocks to gr-network, which causes a name change of the id. See Porting_Existing_Flowgraphs_to_a_Newer_Version for details.

Parameters

Interface name
Device name to create
MTU
Maximum Transmission Unit size
Flag
Flag to indicate TUN or Tap

Example Flowgraph

Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI. Currently we have no standard method of uploading the actual flowgraph to the wiki or git repo, unfortunately. The plan is to have an example flowgraph showing how the block might be used, for every block, and the flowgraphs will live in the git repo.
