Because Windows. You don't get to *understand*; you just get to work around the brokenness. And drink. I've had reports of something similar happening with OpenConnect on a German Windows installation too. At http://lists.infradead.org/pipermail/openconnect-devel/2015-June/003033.html is a log showing the interface name failing for some operations, and working for others: 2015-06-17 10:48 executing: netsh interface ipv4 set subinterface "Ethernet= 2" mtu=3D1342 store=3Dactive 2015-06-17 10:48 Element nicht gefunden. 2015-06-17 10:48 Configuring "Ethernet 2" interface for Legacy IP... 2015-06-17 10:48 executing: netsh interface ip set address "Ethernet 2" sta= tic 137.248.72.208 255.255.255.0 2015-06-17 10:48 Element nicht gefunden. 2015-06-17 10:48 executing: netsh interface ip add wins "Ethernet 2" 192.16= 8.16.26 index=3D1 2015-06-17 10:48 executing: netsh interface ip add dns "Ethernet 2" 137.248= .1.5 index=3D1 2015-06-17 10:48 executing: netsh interface ip add dns "Ethernet 2" 137.248= .21.22 index=3D2 2015-06-17 10:48 done. Besides, route addition doesn't use the network interface name on Windows, does it? FWIW the reporting user said that *renaming* the interface would make the problem go away: http://lists.infradead.org/pipermail/openconnect-devel/2015-July/003088.html --=20 dwmw2
