Firewalld 已启用以下端口 1723/tcp

我的options.pptpd如下

name pptpd
refuse-pap
refuse-chap
refuse-mschap
require-mschap-v2
ms-dns 8.8.8.8
ms-dns 8.8.4.4
proxyarp
lock
novj
novjccomp
nologfd

请问有人可以让我知道我哪里做错了吗？我还应该在防火墙中启用什么吗？

谢谢

谢谢，但问题已解决，因为防火墙阻止了 pptp.conf 中配置的本地和远程 ip

问题已通过以下命令解决：firewall-cmd --add-source=xx.xx.xx.x/24

谢谢
