OpenVPN Support Forum

Hi, i'm running openvpn 2.1.4 in contOS 5.5 and having problem connecting with client connection to protocol UDP port 80. It worked fine with TCP port 80 but under UDP in displays
TLS Error: TLS key negotiation failed to occur within 60 seconds
Client internet connection is fine but still it is unable to connect to server. Server log does not show any changes.
Is it with the server firewall or what because I'm not good when it comes to iptables and firewall.

Anyone can show me ho to do this if its with my server firewall settings?

Thaks!^^

sounds like a firewall issue OR an 'selinux' issue; try disabling the firewall to see if it makes a difference: if you can connect afterwards then you know it's your firewall; if not then it might be an 'selinux' issue. Set 'selinux' to 'disabled' in /etc/sysconfig/selinux and reboot and see if that helps.
