本地端口转发 - macOs Big Sur

Question

我需要将所有发往 127.0.0.1:5432 的流量转发到 macOS Big Sur 上的 192.168.1.103:543。Windows 上的类似命令是

netsh interface portproxy add v4tov4 listenaddress=127.0.0.1 listenport=5432 connectaddress=192.168.1.103 connectport=5433

谢谢。

您可以使用 rdr 命令将流量从 127.0.0.1:5432 转发到 192.168.1.103:543

echo "

rdr pass on lo0 inet proto tcp from any to self port 5432 -> 192.168.1.103 port 543

rdr pass on en0 inet proto tcp from any to any port 5432 -> 192.168.1.103 port 543

rdr pass on en1 inet proto tcp from any to any port 5432 -> 192.168.1.103 port 543
