user tracking don't display all host IP under VLAN

[prasetiohadi]

I have problem using User tracking utility, I am installed LMS 2.5 under Win 2000 Server SP4 and my Network using two 6506 and 2 Firewall Blade module.

from about 250 hosts detected only 2 host ip address appears and the other blank.

before i deploy vlan (Flat) there is no problem using user tracking.

Cisco.com says that this problem maybe because of IP default gateway problem, but i already checking and fix it.

Anyone know how to solve this problem ?

For addition after i read user tracking problem thread from Mr.moazzam.ali2.I Found that UT read IP address from Router.

And I think that is true because 2 detected hosts is hosts that that remain existing in VLAN in 6500, the other user on other vlan that already moved to firewall blade is not detected.

So is IP address can be found on user that reside on Firewall ?

or maybe any special configuration either on LMS or Blade ?

Anyone can help this problem ?

Tks.
