Forefront TMG disconnected a non-TCP connection

Hi,

I am getting the following error alerts in  TMG

Forefront TMG disconnected a non-TCP connection from 192.168.0.1 because the connection limit for this IP address was exceeded. Larger custom connection limits should be configured for the IP addresses of chained proxy servers and back-to-back Forefront TMG computers with a NAT relationship. 

This error show two msgs for my both dns servers.

My DNS servers Ip addresses

192.168.0.1

192.168.0.2

Please help me out

Thanks
