Port forwarding and blocking

I got a UTM5 and for some unknown reason ports such as 445 are not even hitting the firewall. No packets are even touching this thing which leads me to belive my isp (Time Warner) is blocking. I spoke to three level 3 techs who all confirm Time Warner does NOT block and ports. I have other ports open and working fine such as 3389. My modem is Netgear CM600. Netgear Level 2 support is clueless to what is happening since the utm5 is configured properly.

Does anyone have any idea what the problem is?
