Same problem here - Recently upgraded to new high speed cable service (Telstra Bigpond Australia) using DOCSIS3.0 Gateway Modem (Netgear CG3100) and now I cannot use Matchmaking in Halo Reach or Halo 3 ODST. The new high speed 3.0 cable service from Telstra uses 101.x.x.x IP addresses so looks like we are all in the same boat!! WTF!! Surely this cannot be that complicated to rectify - Something must be going on with 343i for them not to fix this, are they too busy developing Halo 4, have they blocked these IP addresses for development reasons or are they simply incapable of employing technicians to do their F*&^ing job correctly???? How can a simple user be expected to navigate their way around the mess of ISPs that don't know their pings from their packets, Microsoft who seem to not give a **** once they have sold you the product, XBOX Live who pass the buck all the time & 343i who seem like a ghost company that nobody works for???? Thanks to everyone that has posted here and on other forums - lets keep pushing these people and challenge their integrity.
