Tuntap

The TunTap project provides kernel extensions for Mac OS X that allow to create virtual network interfaces. From the operating system kernel's point of view, these interfaces behave similar to physical network adapters such as an Ethernet network interface.However, the virtual interface does not...

As Mac OS X has not implemented the GRE virtual network, it is somewhat unpleasant using general tunnel such as TUN/TAP, so, it comes here, gre for OSX Platforms: Mac

PyTap provides an object-oriented interface to Linux' TUN/TAP device. It can be used to easily build TUN/TAP VPN daemons and software that generally introspects network traffic on such devices. #md5=fcb9a2ea9fc57f1cfcccec1800855531 #md5=7f391baa4cf317491e124c18c250ad66 Platforms: *nix

libdnet provides a simplified, portable interface to several low-level networking routines, including network address manipulation kernel arp(4) cache and route(4) table lookup and manipulation network firewalling (IP filter, ipfw, ipchains, pf, PktFilter, ...) network interface lookup and...

tunctl is used to set up and maintain persistent TUN/TAP network interfaces, enabling user applications to simulate network traffic. Such interfaces is useful for VPN software, virtualization, emulation, simulation, and a number of other applications. Platforms: *nix
