Hello,

You can do one of two things:

a) Create second tunnel between 10.20.30.0/24 and 192.168.2.0/24. Use 
exactly the same settings as the existing tunnel, just change the IP 
addresses.

b) On the existing tunnel change the subnet mask on the 192.168.1.0 entry to 
/23. This will then include all IPs in the range 
192.168.1.0-192.168.255.255.

You can't route packets over IPSEC tunnels in the traditional sense. 
Commercial products that can do this either negotiate a tunnel for all 
addresses or use some form additional encapsulation, such as GRE.

Regards,

Kris.
