Packets gets lost. He gets the first IPv4 too (192.168.40.1, .0 in ipp.txt), but IPv6 works fine. Strangely enough, the incriminated IPv6 responds to ping even if no client is connected: {{{ root@OpenWrt:~# ping :: PING :: (::): 56 data bytes 64 bytes from ::254: seq=0 ttl=64 time=0.377 ms 64 bytes from ::254: seq=1 ttl=64 time=0.262 ms 64 bytes from ::254: seq=2 ttl=64 time=0.257 ms 64 bytes from ::254: seq=3 ttl=64 time=0.261 ms ^C --- :: ping statistics --- 4 packets transmitted, 4 packets received, 0% packet loss round-trip min/avg/max = 0.257/0.289/0.377 ms }}} Workaround: add a dummy entry in ipp.txt to ensure that no client gets the first IP Cheers, NicolaF_" Bug / Defect closed minor release 2.5 IPv6 OpenVPN git master branch (Community Ed) Patch Queue: New / awaiting ACK fixed Antonio Quartulli
