Ping and reply from inside to dmz and vice versa

I'm just starting off on ASA's and i'm out of ideas here with this problem. I simply want to be able to ping from inside to dmz and vice versa. At this time i don't have any servers in the dmz except for the dmz interface which is, my inside network is 192.168.50.x.

I think i may have my static nat incorrect. if anyone could shed some light on this i would greatly appreciate it. I've also read numerous other discussions online but each one differs from the other.

Thanks all,

Ping and reply from inside to dmz and vice versa

Hello Cesar,

Looks good the configuration

You said you do not have any host on the DMZ

If you are trying to ping the DMZ interface from an inside host that will not work as you cannot ping a far end interface.

Place a host on the DMZ interface and run a test.

Any other question...Sure..Just rate all of my answers.
