Hi there,
"For example: On one server, vpn client can not access the services publishing to the Internet while other services not publish to the Internet on the same server remains accessible via vpn client"
Include public address into the tunnel by the means of split-tunnel.
"while other services not publish to the Internet on the same server remains accessible via vpn client"
Your client accessing none-publish service via the private address, right ?
thanks
