Multiple vpn setup with same subnet for remote control

I must configure the following.

On oure head office whe have a cisco 827 router, i must configure this that it make's a connection to at least 3 other side's wich also hava e cisco 827. We having a ADSL conection with static ip adresses.


    main office<----->internet |<---------->office one  <192.168.10.0>
192.168.50.0                        |                
                                           |<---------->office two  <192.168.20.0>
                                           |
                                           |<---------->office three <192.168.10.>

So i need three vpn connection's, but i have also two site with the same subnet.
I need this config because on oure main office we want to setup a monotoring tool.

I don't believe this is possible. The remote network must be on a spearate subnet otherwise there is no way it will hit the gateway and travel over the vpn tunnel. This is by design with TCP/IP. What you really want to achieve is some kind of bridged connection between Office one and Office three.
