Permanently add routes to iMac running OS 10.7

Question

My iMac gets its ip address and default gateway from a windows DHCP server.It fails to pick up the static routes from the DHCP server for my other internal network, which is not accessable via the default gateway device.I can make it so that the computer can picj up these routes but then the info is removed on reboot! Need to find a way of being able to permenantly adding the routes to the Mac either through a specific file or startup scriptOther ones i have tried do not seem to work for OS 10.7If anyone can help that would be great!

Hi,Not sure if you have fixed this, but I&#x27;d use launchd to create the route on startup.If you create a text file in /Library/LaunchDaemons/local.imac.route.plistwith:&lt;?xml version&#x3D;"1.0" encoding&#x3D;"UTF-8"?&gt;&lt;!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"&gt;&lt;plist version&#x3D;"1.0"&gt;&lt;dict&gt;          &lt;key&gt;Label&lt;/key&gt;          &lt;string&gt;local.imac.route&lt;/string&gt;          &lt;key&gt;OnDemand&lt;/key&gt;                    &lt;false/&gt;          &lt;key&gt;ProgramArguments&lt;/key&gt;                    &lt;array&gt;                              &lt;string&gt;route&lt;/string&gt;                              &lt;string&gt;add&lt;/string&gt;                              &lt;string&gt;[NETWORK/16]&lt;/string&gt;                              &lt;string&gt;[GATEWAY]&lt;/string&gt;                    &lt;/array&gt;          &lt;key&gt;KeepAlive&lt;/key&gt;                    &lt;false/&gt;          &lt;key&gt;RunAtLoad&lt;/key&gt;                    &lt;true/&gt;          &lt;key&gt;ServiceIPC&lt;/key&gt;                    &lt;false/&gt;          &lt;key&gt;UserName&lt;/key&gt;                    &lt;string&gt;root&lt;/string&gt;&lt;/dict&gt;&lt;/plist&gt;You need to replace [NETWORK/16] with the network you are trying to add, like 10.15.14.0/24 or 10.0.0.0/8and [GATEWAY] with the IP address of the gateway to use like 10.11.12.13Then as root (login as an admin user and use "sudo su -" to become root) type:launchctl load /Library/LaunchDaemons/local.imac.route.plistYou should be up and running.

Hello,I know this thread is a little old but need additional help with this if possible. What&#x27;s written above works great but I need to apply this to the wireless interface. Is this possible? Does the local.imac.route.plist file apply to all interfaces?Thanks,Tony
