Question

I am trying to install VPN tunnel through SMPP on my centos server and need help or some tutorial which shows how to do it.

Answer 1

I think what you want to achieve it create a VPN tunnel connection form your system/server to another system/server that has SMPP installed

Brief Information on VPN : http://www.centos.org/docs/5/html/Deployment_Guide-en-US/ch-vpn.html

it does not matter if its HTTP , SMTP , SMPP , or simple socket solution .. when you have a VPN connection you an force all traffic to use that connection
