You are routing the outside interface to itself ??

If you can count on proxy arp, then just do a basic configuration, ip address the inside, ip address the outside, nat (inside) 1 the internal IP address range, global (outside) 1 interface and make sure the default route is set to the next hop.
If you cannot count on proxy arp, then the configuration is as above but the router must also be specifically set to route the appropriate subnet to the PIX.
If you want the outside to see the internal IP addresses unchanged, then static (inside, outside) xxx.233.235.0 xxx.233.235.0 netmask 255.255.255.0 and skip the nat and global statements; after that it is as per above, except that it becomes increasingly likely in that case that you will need to have the router explicitly route the internal IPs to the outside interface of the PIX.
