We're working with a Cisco ASA 5520 with older 8.2 code and in doing a sniff, I'm seeing some private IP's coming through the ASA and trying to get out. Some of them to public IP's and some to private IP's such as 10.10.10.10. As the ASA is setup with NAT and working, i would have thought if it was a simple access list issue, I wouldn't see the private ip of the internal host? What could be cause it not to show up as the global ip or nat? In fact, netbios was shown on the outside as well so you could see the device's name. It couldn't get anywhere, but you could still see it. Any ideas?
