Lost of connectivity between routers on private NW..

Hi,

is there anything blocking the tcp communication between the two ICM sides?

TCP reset does not happen just out of the blue.

Pls check the port Blocking and TCP Chimney Offload configuration.

Thanks for the update.

For the Offload, we disabled the configuration as per the following post:

Can you elaborate on the port blocking? you mean from the server side or the network side?
