I config the static nat in pix and use global / nat command to make source nat for inside host's internet connection. But when i try to connect the map ip config in pix as static ip, it dosen't work. I sniffor the packet and find the the source ip address which response from remote server(pix) is still the private ip address of the inside host, and hasn't been translate to public ip address.
and the ping result is :
C:\>ping 218.x.179.3 -t
Pinging 218.x.179.3 with 32 bytes of data:
Reply from 10.0.0.3: bytes=32 time=25ms TTL=55
218.x.179.3 is the map ip address.
10.0.0.3 is the host ip address.
and show xlate is :
4 in use, 14 most used
Global 218.x.179.4 Local 10.0.0.4
Global 218.x.179.3 Local 10.0.0.3
Global 218.x.179.5 Local 10.0.0.5
Global 218.x.179.6 Local 10.0.0.6
seems ok, too.
why pix dose't translate the inside ip to the map ip? is it bug in 6.3(1) os???
the configuration is the following:
