NIPS inspection dropping legitimate ( Telnet/ SSH ) traffic

We are haing ASA SSM 40 module NIPS at perimeter network. When I keep  the IPS in promiscuous mode then eveything is workign fine and when i had configured the same module in inline mode then i am not able to take putty or telnet of the internet router.

During the inline mode,  IPS is drooping our telnet and SSH traffic and also event is also not genrating the for the same.

We have tried to find the traffic event for router ip and as well as for my system ip. nothing is showing in event.

I used the command sh event from CLI and also checked from ASDM alsbut not getting any scusses.

NIPS IOS version is 7.1(4)E4.

Please help me for the troubleshooting for this issue.
