I want to connect to AirVPN-Servers via SOCKS5 Server which supports UDP packets. So I added the line
socks-proxy sockshost 1080 login.txt basic
to my AirVPN-OpenVPN configuration file.
Connection to SOCKS was successful, but not to your OpenVPN server:
Wed Dec 16 10:44:55 2015 us=732339 UDPv4 link local: [undef] Wed Dec 16 10:44:55 2015 us=732453 UDPv4 link remote: [AF_INET]184.108.40.206:2018 WWWWW
Do you block incoming SOCKS connections (perhaps from common SOCKS ports?) to your OpenVPN-Servers?
