We ran into a similar problem with the MAC clean access agent when connecting to the VPN. We called TAC and it was bug on the MAC Clean Access agent which has not been fixed. It appears that the VLAN detection module on the MAC Clean Access Agent clears the ARP table which was causing the VPN client to disconnect and reconnect.

Cards from AT&T and T-Mobile running especially on MAC OS 10.6 do not work. The MAC is able to login into the VPN fine but then the NAC agent does not launch and run the posture assessment. Have any of you had any experience with this? We have opened a case with Cisco but the tech seems stumped. Thanks.
