site to site vpn which has same private ip address

[kjanakiraman]

Hi,

How can i configure site to site vpn where both the sites have the same private ip address and subnet mask like 10.x.x.x 255.0.0.0. Is there any document that deals with this type of scenerio. Can some one help me in this.

Thanks in Advance

Hi,

With overlapping private network, you can use nat together with IPSEC to deal with, here is the sample config:

Thanks a lot. Is the procedure same for the Cisco Pix Firewall 515 or is the configuration different.

Thanks in Advance
