But it can never be efficient because of http://sites.inka.de/bigred/devel/tcp-tcp.html Also it prevents *desired* behaviour of no attempts to deliver dropped packets (well, UDP nature). It is completely good, simple, tempting and acceptable solution for the mesh network, but not the replacement for VPN between two hosts, between machines in the LAN, for multi-gigabit datacenter solutions and that kind of things. I was only concerned about that kind of use-cases. -- Sergey Matveev (http://www.stargrave.org/) OpenPGP: CF60 E89A 5923 1E76 E263 6422 AE1A 8109 E498 57EF
