Re: PIX Outside NAT and Overlapping networks = No route to host
Yes, it is broken. The solution is to connect 2 overlapping nets with the IPSec tunnel. IPSec picks up the returning packet 172.16.1.10 (192.168.1.4 before NAT) -> 192.168.1.112 (192.168.2.112 before NAT) encapsulates it and sends it to the IPSec peer. After that routing process routes it to the IPSec peer wtihout any problem.
