OpenVPN connecting error! Process restart

Hi Everyone!

Fingers are crossed as i have worked on this issue from few days but no success yet. I have configured VPN at my VPS following this tutorial: http://servertutz.wordpress.com/2011/08/14/installing-openvpn-on-centos/

Here is my server.conf settings:

local 192.***.**.*** #- IP address hidden at forum
port 9911 #- change the port you want
proto tcp #- protocol can be tcp or udp
dev tun
tun-mtu 1500
tun-mtu-extra 32
mssfix 1450
ca /etc/openvpn/easy-rsa/2.0/keys/ca.crt
cert /etc/openvpn/easy-rsa/2.0/keys/server.crt
key /etc/openvpn/easy-rsa/2.0/keys/server.key
dh /etc/openvpn/easy-rsa/2.0/keys/dh1024.pem
plugin /usr/share/openvpn/plugin/lib/openvpn-auth-pam.so /etc/pam.d/login

I configured it to work on Pfsense. I have 2.0.3-RELEASE (amd64) FreeBSD 8.1-RELEASE-p13 installed. Here is the configuration at my Pfsense:

and here is the log error i get:

Okay I solved it. Don't know how exactly! but let me tell if someone like me having issue with this.

What I have done:=>

1. In sever conf file, i have changed TCP into uDP and port into 2500. looks probably it was because port before was blocked or something like that.

But now another problem,, I cant browse anything from that VPN? Is this problem from Server-side or client-side pfsense?
