NetworkManager를 사용하여 OpenVPN에 연결하는 방법

OpenWrt 10.03 라우터에 OpenVPN 서버를 설치했습니다. [새 새로 고침]:https://pastebin.com/raw.php?i=hRECWuf1

"괜찮아"인 것 같습니다.

내 컴퓨터를 라우터의 LAN 포트에 연결하고 한 번 사용해 보고 싶었습니다. 저는 Fedora 14와 GNOME을 사용하고 있습니다. NetworkManager 애플릿에서 다음을 설정했습니다.이것그리고이것. 좋아요! 연결을 시도했지만 실패했습니다. 로그는 다음과 같습니다.https://pastebin.com/raw.php?i=gv2xChxW

한 가지 중요한 점: 내 라우터[openvpn 서버가 있는 라우터] IP 주소는 192.168.1.2이며 어디에도 쓸 필요가 없습니다. 그렇다면 네트워크 관리자 애플릿은 내 openvpn 서버의 IP 주소를 어떻게 알 수 있습니까? 그게 문제인거 같은데 192.168.1.2를 어디에 써야할지 모르겠네요

ps: 예, Google에서 검색을 시도했습니다. "서버 인증서 확인 방법이 활성화되어 있지 않습니다." 그러나 아무것도 발견하지 못했고 지금까지 몇 시간 동안 노력했습니다... :\

ps [다시..]: 예, 인터넷 검색을 시도했습니다. "서버 인증서 확인 방법이 활성화되어 있지 않습니다." 그러나 아무것도 찾지 못했고 지금까지 몇 시간 동안 노력했습니다... :\

추신: 라우터에서 이 작업을 수행하는 경우:

iptables -P INPUT ACCEPT
iptables -P FORWARD ACCEPT
iptables -P OUTPUT ACCEPT
iptables -t nat -P PREROUTING ACCEPT
iptables -t nat -P POSTROUTING ACCEPT
iptables -t nat -P OUTPUT ACCEPT
iptables -t mangle -P PREROUTING ACCEPT
iptables -t mangle -P OUTPUT ACCEPT

그리고 stat tcpdump를 실행하고 내 컴퓨터에서 연결을 시도했지만 아무 일도 일어나지 않습니다! ..그래서 네트워크 관리자 애플릿에 오류가 있는 것입니다! ?

다시 말씀드리지만 추신: 그렇게 한다면:

$ telnet 192.168.1.2 1197
Trying 192.168.1.2...
telnet: connect to address 192.168.1.2: Connection refused

[openwrt 라우터의 Pastebin 링크에서와 같이] 이러한 종류의 openvpn을 설정하는 좋은 방법이 있습니까? 다른 openvpn 클라이언트 프로그램을 찾아볼 가치가 있나요? [Network Manager 애플릿 제외]
