Router question

[whenever]

anyone know if this works:

--------        ----------------------------          ---------------
The    |        | Cisco 25xx               |          | Linux Router|
Colud  |--------|23.24.25.26    192.168.0.1|----------|192.168.0.2  |
       |        |                          |          |             |  
--------        ----------------------------          |             |
	                                              |190.191.192.1|
                                                      ---------------
                                                             |
                                                             |
                                                       --------------
                                                       |    LAN     |


Config:
1) cisco with static route 190.191.192.0/24 gw to 192.168.0.2
   0.0.0.0 gw to the other end of the colud

2) Linux 0.0.0.0(default route) to 192.168.0.1

3) LAN host's default route to 190.191.192.1

will I encounter any problems by joining 2 routable networks with a non-routable(private ip) network ? have anyone tried this to save ip before? how does traceroute looks from outside to the 190.191.192.0 network ?  Will I cause any problem to the internet when I am doing this?  The reason for this is to use Linux's Class Based Queueing for bandwidth management. 

Thanks for your help
