502坏网关

Question

我运行了以下iptables命令来启动pptp服务器：

iptables -A INPUT -i venet0 -p tcp --dport 1723 -j ACCEPT
iptables -A INPUT -i venet0 -p gre -j ACCEPT
iptables -A FORWARD -i ppp0 -o venet0 -j ACCEPT
iptables -A FORWARD -i venet0 -o ppp0 -j ACCEPT
iptables -t nat -A POSTROUTING -j SNAT --to-source 33.122.21.177

但它破坏了php服务。Nginx返回一个错误“502坏网关”。Nginx错误日志

failed (104: Connection reset by peer) while reading response header from upstream, client: 199.239.99.13, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000"

php服务正常运行。

service php-fpm status
php-fpm (pid  14157) is running...

你能告诉我如何解决这个问题吗？

Answer 1

我找到了解决办法。

我只需要运行命令

iptables -t nat -D POSTROUTING -j SNAT --to-source 33.122.21.177
