All, I'm seeing unexpected behavior with Linux and NAT through a Cisco PIX. The problem can be seen with a simple traceroute. When I trace to a NAT'd system, the Linux system gets the "real" IP rather than the NAT'd IP. [root@linux-system root]# traceroute 10.254.41.226 traceroute to 10.254.41.226 (10.254.41.226), 30 hops max, 38 byte packets 1 10.83.131.240 (10.83.131.240) 0.924 ms 0.871 ms 0.877 ms 2 10.254.41.226 (10.254.41.226) 0.842 ms 0.632 ms 0.560 ms 3 192.168.41.226 (192.168.41.226) 0.671 ms 0.614 ms 0.631 ms But from a AIX system, I get: AIX-System# traceroute 10.254.41.226 trying to get source for 10.254.41.226 source should be 10.83.131.48 traceroute to 10.254.41.226 (10.254.41.226) from 10.83.131.48 (10.83.131.48), 30 hops max outgoing MTU = 1500 1 10.83.131.240 (10.83.131.240) 3 ms 1 ms 1 ms 2 10.254.41.226 (10.254.41.226) 2 ms 1 ms 1 ms 3 10.254.41.226 (10.254.41.226) 2 ms 2 ms 2 ms Causes? reasons? Ideas? I don't manage the PIX, so if someone here manages one, has seen this, and knows the fix. Please advise...
