Adding my local network (where server is) to OpenVPN without using OpenVPN clients on it

Question

I installed OpenVPN on a Funtoo system sucessfully: it works! I use default ips so my server is 10.8.0.1 and the clients conneted to it have IPs auto-asigned.

The problem is that I need to access to some computer on the network and looking on the OpenVPN config file I see that I can push my network:

# Push routes to the client to allow it
# to reach other private subnets behind
# the server.  Remember that these
# private subnets will also need
# to know to route the OpenVPN client
# address pool (10.8.0.0/255.255.255.0)
# back to the OpenVPN server.
;push "route 192.168.10.0 255.255.255.0"
;push "route 192.168.20.0 255.255.255.0"

The problem is that this is a local ADSL, where the network is the default 192.168.1.X and I can't change that (I can't access to the router, it's blocked by the ISP).

My question is, I can push a local IP to a OpenVPN ip? Because, if I push 192.168.1.X to a client that has the same routing at home can conflicts with his network, no?

Thank you in advance!

My question is, I can push a local IP to a OpenVPN ip? Because, if I push 192.168.1.X to a client that has the same routing at home can conflicts with his network, no?

Exactly. It will be conflict between server subnet and client subnet. The solution is use different subnet for the client.

The problem is that this is a local ADSL, where the network is the default 192.168.1.X and I can change that (I can't access to the router, it's blocked by the ISP).

What? The ISP shouldn't block your router. If you have ISP account (I assuming PPPoE username & password), you can reset your modem and re-configure.
