VPN Overlapping issue

Dear Techie,

    Having a doubts in Site to site VPN,

I have 3 customer, cust1--- cust2 ---- cust3,

the private ip address is ,
Cust1 ---- 10.2.2.0 (PIX)
Cust2 ---- 10.10.10.0 (Checkpoing Nokia)
Cust3 ---- 10.2.2.0 (ASA)

connectivity is Cust1 ---- Cust2 ---- Cust3
                         | | |
                    10.2.2.0 10.10.10.0 10.2.2.0

I want to achive a site to site VPN tunnel between Cust1 -- Cust2 & also
Cust2 -- Cust3 . But, here the cust1 and cust3 having a same private ip
address range. So, when establishing a VPN tunnel in Cust2 with cust2 to
cust1 & cust2 to cust 3, there will be a confict between the 10.2.2.0
series range.

I know that there is an overlapping network. have seen the cisco site as
well

But this is somewhat different scenario as i understand.

Can anyone help me to resolve the issue.
Thanx

Regards,
Manoj
