In that case, you're stacking TCP over TCP, which does not work very well. See http://sites.inka.de/~W1011/devel/tcp-tcp.html for a pretty good (technical) explanation on why that is the case. If you stack it over UDP instead (e.g., with OpenVPN), you should be fine. -- < ron> I mean, the main *practical* problem with C++, is there's like a dozen people in the world who think they really understand all of its rules, and pretty much all of them are just lying to themselves too. -- #debian-devel, OFTC, 2016-02-12 ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Nbd-general mailing list Nbd-general@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/nbd-general
