How can I do a permanent port forwarding on my Mac Catalina:

  • it will run on background
  • it will work after reboot
  • FW is off

Today I use command:

ssh -L 5900:localhost:5901 localhost

But it runs on foreground and closes after computer restart. So, I need something like this command BUT with 3 requirements that I wrote above. Is it possible?

Ok, I think that I found the possible solution for me:

  1. sudo touch /etc/pf-xxx.conf

  2. Write to the file(/etc/pf-xxx.conf): I did it for my vnc ports

    rdr pass inet proto tcp from 127.0.0.1 to 127.0.0.1 port 5901 -> 127.0.0.1 port 5900

    rdr pass inet proto tcp from 127.0.0.1 to 127.0.0.1 port 5902 -> 127.0.0.1 port 5900

  3. Create & edit com.apple.pfctl-xxx.plist <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Disabled</key> <false/> <key>Label</key> <string>com.apple.pfctl-xxx</string> <key>WorkingDirectory</key> <string>/var/run</string> <key>Program</key> <string>/sbin/pfctl</string> <key>ProgramArguments</key> <array> <string>pfctl</string> <string>-e</string> <string>-f</string> <string>/etc/pf-xxx.conf</string> </array> <key>RunAtLoad</key> <true/> </dict> </plist>

  4. sudo chown root:wheel /Library/LaunchDaemons/com.apple.pfctl-xxx.plist

  5. sudo chmod o-w /Library/LaunchDaemons/com.apple.pfctl-xxx.plist

  6. sudo launchctl load /Library/LaunchDaemons/com.apple.pfctl-xxx.plist
