Configure server to listen on UDP IPv4 and IPv6 simultaneously
Posted: Sat Oct 14, 2023 7:53 pm
Hello,
I am trying to configure OpenVPN server to listen both on IPv4 and IPv6 UDP simultaneously, thus in my server.conf I've set, as said in OpenVPN documentation https://openvpn.net/community-resources ... envpn-2-5/, variable proto udp.
Unfortunately when I try to list open ports using netstat -tunlp I have there open only port for IPv6/UDP
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
udp 0 0 0.0.0.0:1194 0.0.0.0:* -
Do I understand the documentation correctly that if in server.conf is set proto udp, server should listen both on IPv4 and IPv6, or do I have to make any other changes?
Thank you for your advice!
