Masquerading the same IP network range with OpenVPN

["Victor Rodriguez Cortes" <victor.rodriguez@valmesa.es>]

Hi

I have quite experience using VPNs with OpenVPN. But I don't know how to
handle this.

My problem is than both sides of the vpn have the same subnet range:

Network A                                                   Network B
192.168.0./24 openvpn<----VPN----> openvpn 192.168.0./24

It's imposible change the range of both subnets. The question is: Can I mask
one of the sides?

For example:
I wanna ping from a host placed A to a host placed in B, (for example to
192.168.0.5). In a host pf network A I will ping 192.168.X.5  (Where X is a
different network other than 0). The openvpn router will make the translation
(using ipmasquerading I think ) from 192.168.X.5 to 192.168.0.5 in the B
network and the B host should will be able to reply it.

The Idea is (remember, X!=0):
Network A                                               Network B
192.168.0./24 openvpn <----VPN----> openvpn 192.168.0./24
                                                      masqueraded subnet
                                                            B' 192.168.X/24

I think It's possible using ip masquerading but I'm not sure.
Thanks a lot for your help!

Regards
