Macos 本地源流量的pf-NAT

我正在尝试代理来自我的机器的22个流量，因此它将被代理/转发到远程服务器。这对ipfw来说很容易，但约塞米蒂只有pf

有人知道如何在OSX Yosemite上的本地（源于机器）流量上进行rdr吗

这不管用

# Custom pf Rules
#######################################
# target_ip is the ip of which I would like traffic to be proxied  
target_ip = "10.0.0.2” 
# porxy_ip is the proxy address 
porxy_ip = "192.168.1.100”


rdr pass log on lo0 proto tcp from en0 to $target_ip port 80 -> $porxy_ip port 8080

pass out on en0 route-to lo0 inet proto tcp from en0 to $target_ip port 80 keep state

# End

有什么建议吗
