group type cannot be changed once it has been created.
The cfgFilterNetworkGroupTable is used for managing
information about IP Addresses.
The cfgFilterIpProtocolGroupTable is used for managing
information about protocols.
The cfgFilterIpServiceGroupTable is used for managing
information about services(ports).
The cfgFilterICMPGroupTable is used for managing
information about ICMP protocol.
The cfgFilterNestedGroupTable is used for supporting
nesting of filter groups(i.e configuring filter groups
inside the other filter groups).
