Lee,
You need to configure your NAT in such a way that BGP traffic is
not in the inside local pool. Try something like this:
ip nat inside source list 100 interface atm0/0/0 overload
!
access-list 100 deny tcp any any eq bgp
access-list 100 deny tcp any eq bgp any
access-list 100 permit ip any any
BGP is matched as both source and destination because you don't
know in which direction the BGP session was initiated.
HTH,
