4G?

putting vita on dmz is working fine too bad have to ignore ps3 on dmz... sorry abe ninja last nite bck home late, the moment i play u already log of, so only managed to join 1 session smoothly yesterday lol really so addict!

High possibility that you're on NAT TYPE 3.

Go to Settings > Network > Internet Connection Test.

And check what NAT TYPE you're currently on. If NAT TYPE 3, definitely not suitable for KZM.

If you're using normal router, it's possible to change from NAT 3 to 1/2 using DMZ or port forward.
But if using Celcom Broadband, I have no idea. Anyone else have experience with port forward on Celcom BB modem?

@jieson77~ can you access your modem menu? i.e: using http://192.168.1.1 at browser

if it's a USB stick modem, I'd be surprised if you can change the NAT Type.
especially since the laptop acts as a secondary transmitter.

I just tried my Mifi device (mobile router) and got a NAT Type 3 as well.

My guess is that 3G based routers/internet services will always get NAT Type 3.

sometimes free wifi networks block ports used by online games :/

no harm trying,though.

so sad dont have the beta try...

Wow some of the Intel needs some brainstorming. And also need certain equipment to get. I guess it needs to be replayed, but the saving part sux. Have to restart the missions..
