Site to Site - No routing over established p1 &p2

Guys!

Have a slight situation where as we are trying to connect our CC to a CISCO ASA… We have the phase 1 and phase 2 all connected and the connection has been established. However we are unable to transmit any data over the tunnel.

We have placed NAT rule: srcnat from Src.Address ( our internal vlan range ) to Des. Address ( the cisco asa internal range ). Unable to ping/see anything of each others network?

Does anyone have any words of wisdom?

Thanks in advance!
