I tried IceFloor, but it's not working to white list all traffic from a single IP to bypass firewalls.

  • In a specific way or just access? SSH? Remote?

  • Initially it's a local IP accessing a webserver. May 28, 2012 at 13:58

The firewall in Mac OS X v10.5.1 and later is an Application Firewall, which allows you to control connections on a per-application basis, rather than a per-port basis. This makes it easier to gain the benefits of firewall protection, and helps prevent undesirable applications from taking control of network ports that have been opened for legitimate applications.

You can not limit or allow access via ip address using the OS X firewall. You can use ssh and set restrictions in /etc/sshd_config. For limiting to certain ip addresses only see this answer.
