I have upgraded to 7.2(2) from 7.0(7) and I'm having the following problem.
I have two interfaces Outside 192.168.1.1/23 and Inside 172.16.1.10/24. I'm using the following static nat to hide addresses static (outside,inside) 172.16.20.0 192.168.1.0 netmask 255.255.255.0. When trafic for the network 172.16.20.0/24 arrives to the inside I receive a No route to host error.
The same configuration is working fine on PIX 7.0(7) and this problems I found it also in 7.2(3) 7.2(3)-12 8.0(2).
Does any one know what has changed in 7.2 or grater that makes this haven? any ideas to resolve this?
