请教pptp修改1723端口的问题

honggaoyan

server和client两端都是在内网的linux机器,server端的路由器上只做1723/1723的映射
原来源码编译安装用默认的1723端口配置成功

但是在代码上把1723改为1724后就不行了。
好像是GRE的问题
客户端报如下日志：

pppd[3702]: pppd 2.4.4 started by root, uid 0
pppd[3702]: Using interface ppp0

client 端一开始netstat -anpt能看到pptp的1724的链接的

请教各位，GRE协议只针对1723端口？

ojuba

服务器上47端口也要开发，gre协议走的是这个端口

      问下楼主，pptpd源代码1723端口在那修改啊！

congli

GRE不是47端口,应该是IP 47.
