I want to know which port softethervpn listens to.
Execute command: netstat -alnp | grep vpnserver
root@AtopTechnologies:~# netstat -alnp | grep vpnserver
udp 0 0 0.0.0.0:33147 0.0.0.0:* 4007/vpnserver
udp 0 0 192.168.5.143:1194 0.0.0.0:* 4007/vpnserver
udp 0 0 127.0.0.1:1194 0.0.0.0:* 4007/vpnserver

udp 0 0 0.0.0.0:63972 0.0.0.0:* 4007/vpnserver
udp 0 0 ::1:1194 :::* 4007/vpnserver
udp 0 0 fe80::8ee7:48ff:fe00:1:1194 :::* 4007/vpnserver
