What does this error means? My client.conf file works in other clients like ubuntu. But in centos 5.7 client it is giving this error;

Thu Mar 22 23:20:49 2012 us=231847 UDPv4 WRITE [14] to xx.xx.xx.xx:1194: P_CONTROL_HARD_RESET_CLIENT_V2 kid=0 [ ] pid=0 DATA len=0

Is there selinux enabled or any firewall ?? – B14D3 Mar 22 '12 at 21:31
SELINUX=disabled and I removed iptables – Baran Mar 22 '12 at 21:35
pasting logs from server would be helpful because now it's hard to tell what is wrong... but im considering that server has problem with comunicating with client – B14D3 Mar 22 '12 at 21:47
Nothing happens on server side from this client – Baran Mar 22 '12 at 21:49
can you ping server from client ? – B14D3 Mar 22 '12 at 22:14

It sounds like the packet is being rejected, either by a local firewall or a firewall which responds with an ICMP Destination Unreachable message. Try sending a UDP packet to your VPN server on port 1194 with something like nc -v -u 1194, or run tcpdump to see what response is being received.

Thanks. I can see all the traffic and I can check which ports that it can connect. – Baran Mar 27 '12 at 23:54
