openvpn tun에서 인터넷 사용-Azure Linux -t nat -L Chain PREROUTING (policy

나는이 작업을 수행하려고 OpenVPN TUN온 Azure Linux예 :

-=Android Client=- --> -=VPS=- --> -=Internet=-

클라이언트는 연결하지만 인터넷에 액세스 할 수 없습니다.

iptables 명령

iptables -t nat -A POSTROUTING -s 10.0.0.0/24 -o eth0 -j SNAT --to 191.236.xxx.xxx

(Azure의 공개 가상 인터넷 IP)

iptables -t nat -A POSTROUTING -s 10.0.0.0/24 -o eth0 -j SNAT --to 100.75.xxx.xxx

( eth0로부터 의 IP- ifconfig내부 Azure IP)
