make sure, the port is used open. Example, if use L2TP protocol, generally open udp 500 and 4500.
On centOS server u can use this commend to open port udp 500:
$ sudo iptables -I INPUT -p udp -m udp --dport 500 -j ACCEPT
$ sudo service iptables save

Thanks Budi for pointing this out again,

my mistake. One port was wrongly typed as TCP - not UDP. Now it works.
