Changing tempAgent port in V3 using IP address

Hello,

I've been attempting to use the msdeploy tempAgent setting to deploy to remote machines. I want the listener to run on port 8172 like the Web Handler service would, but it seems that msdeploy will only respect the use of a port if I use the actual computer name and not its IP address. That is,

-dest:auto,computerName='192.168.1.100:8172'

fails, but

-dest:auto,computerName='my.test.machine:8172'

succeeds. Leaving off the quotation marks has no effect. Am I doing something wrong or is this a limitation of the service? Thanks,

- Daniel
