Tracerouting through PIX

[Ricter]

Hi All,
When I traceroute from a switch on the DMZ through the pix to an inside network address I get an odd response:

dmz-switch> (enable) traceroute 161.112.113.232
traceroute to 161.112.113.232(161.112.113.232), 30 hops max, 40 byte packets
1 161.112.113.232(161.112.113.232) 7 ms 7 ms 8 ms
2 161.112.113.232(161.112.113.232) 8 ms 7 ms 7 ms
3 161.112.113.232(161.112.113.232) 7 ms 7 ms 8 ms

All the ips are the same. Is this because the request is coming from a lower security to a higher security interface?
It as if the pix is disguising the internal network ip's

Switch-PIX-INSIDE

Any help is appreciated
Thanks

That is the normal behaviour of the PIX. It is protecting your internal network by hiding the internal details from non trusted users. Otherwise your internal network could be scaned and compromised. Hope this helps!
