More on UMA

May 15, 2007 at 1:45 pm · Filed under imported

I’m peeking at some of the traffic on my T-Mobile UMA phone. Here’s what I’ve found so far.

  • My phone gets an IP from my router (duh).
  • All of the traffic is over port 4500 and going to 208.54.3.1, which is m010336d0.tmodns.net (one of many t-mobile servers for this, I’m guessing).
  • There seems to be something like a 0.03-0.13kb alive message. I see ~20-200kb spikes when calls are initiated

But now I can’t seem to figure out how to capture the packets. Ethereal doesn’t seem to want to capture the phone (or maybe I have a filter that’s hiding all the UMA communications). After struggling to get rflow collector for dd-wrt to shove data into a mysql database (way harder than it should have been…) I learn that only collects the same information as is visible from the UI, nothing about the data. Oh well, another project for another night!
