openvpn 같은 아이디로 다른곳에서 동시 접속시..

안녕하세요

openvpn을 설치해서 사용하고 있는데요.

1.openvpn 서버

2. 외부1

3 외부2

만약 test라는 아이디로 외부1번에서 openvpn 접속을 하고 사용 후 접속을 끊지 않고 연결해놓고 다시 외부2번에서 같은 test아이디로  openvpn 접속을하면 어떻게 되나요?

외부1과 외부2에 두곳 다 접속이 되있는경우 접속이 자꾸 끊어지는 문제가 있어서 서버 로그를 확인해보니 약 2분간격으로 외부1과 외부2에서 같은 사설 아이피로 계속 접속 하는것 같이 보이는데요. 아래와 같은 방법은 없는지 궁금합니다.

1. 외부1에서 이미 접속이 되있는 경우 같은 아이디로 외부2에서 접속할때 자동으로 외부1에서의 접속을  끊어줄수있는 방법

2. 같은 아이디로 접속했을때 다른 아이피를 받을수 있는 방법 (같은 아이디로 외부1이나 외부2에서 동시 사용가능한방법)
