It isn't SOX, but sadly enough, PCI DSS Requirement 1.5 says:
Implement IP address masquerading to prevent internal addresses from
being translated and revealed on the Internet. Use technologies that
implement RFC 1918 address space, such as port address translation (PAT)
or network address translation (NAT)
I know that some auditors want to hold people to that standard.
I stopped working with the credit card people at that point...
