Yes, the configuration is correct, the shaping will be performed at the level of 30 Mbps. Regarding the Bc value, it does not influence the average bandwidth but rather the size of the data burst. There is no special default and if you decided to use the size of 640 kbit then fine, you should just observe whether your applications are running fine with this setting. The relation of CIR, Bc and Tc (Tc is the time in which tokens are refilled to allow further data to be sent when shaping) is given by the formula
CIR = Bc / Tc
Modifying the Bc with the CIR being constant results in different Tc values being used, which in turn translate into different queueing latencies for your packets when being deferred by the shaping mechanism to the next Tc interval waiting for necessary tokens.

The need was to reach an host inside a LAN through a VPN connection managed by the LAN gateway (Cisco 1921).
The LAN gateway performs NAT and there was a dedicate nat rule for the host i wanted to reach through VPN.
