OPenVPN Client is not Accessible from Same Subnet IP

[sudipmaity]

I have recently configured OpenVPN Access Server on My Ubuntu 13.04 64 bit Server . Also i have created 2 OpenVPN Client with static IP by using this tutorial - http://openvpn.net/index.php/access-...n-clients.html .
My OpenVPN Server IP is 54.XX.XX.XX and I have Configured my 2 OpenVPN Client Static IP 54.XX.XX.63 & 54.XX.XX.64. I can Connect through client and access my server. The OpenVPN Access Server is assigning me the the static Public IP 54.XX.XX.64 , Subnet - 255.XXX.XXX.192 , Gateway - 50.XX.XX.1.

The OpenVPN Client Server and Open Access Server Is pinging each other and accessible. But Problem is that OpenVPN client is no accessible from same subnet , neither it is pinging.
