TCP/UDP: Socket bind failed on local address [undef]: Address already

Witam
próbuję zbudować mały serwer OVPN na potrzeby łączenia się z mikrotikiem. Niestety przy komendzie "openvpn /etc/openvpn/server.conf" wyskakuje mi następujący error:

Kod:

Fri Apr  8 09:57:58 2016 OpenVPN 2.3.4 arm-unknown-linux-gnueabihf [SSL (OpenSSL)] [LZO] [EPOLL] [PKCS11] [MH] [IPv6] built on Jan 23 2016

Fri Apr  8 09:57:58 2016 Exiting due to fatal error

W związku z tym errorem i poszukiawaniu w necie zapuściłem narzędzie "netstat -anp | grep 1194". Wynik:

Kod:

Mały update. Zmieniłem port na 1195 i po komendzie openvpn /etc/openvpn/server.conf otrzymuję:

czy ERROR: Linux route add command failed: external program exited with error status: 2 powoduje ze zewnętrzny klient sie nie połączy?


niestety na tym porcie pojawił się ten sam error

Re: TCP/UDP: Socket bind failed on local address [undef]: Address already
