Pix 501 vpn to a Check point firewall

[BEEFjerky]

I have a Pix 501 firewall that I need to connect a vpn tunnel to a Check Point firewall. The company that I am connecting to wants to see my outside address. For some reason I am having trouble NATing to my one outside ip.

I do have another vpn tunnel that doesn't use NAT and it works fine.

global (outside) 1 interface
nat (inside) 0 access-list inside_outbound_nat0_acl
nat (inside) 1 0.0.0.0 0.0.0.0 0 0
