Hi All,
I recently put some access lists on our Internet router to drop RFC 1918 addresses. Internally we use 172.19.x.x. I was surprised to see packets getting dropped from our internal network on the router since everyone going through the firewall should be NATed to the legal address 63.169.12.6. I experienced this on FW 4.0 and now on FW 4.1, both for NT.
Anyone have any idea why some of my internal network addresses are not being completely NATed when going to the outside world? Anyone know of other information that may be leaking through the firewall.
Any help or ideas are appreciated.
Regards
Eric
