Jon,

search www.phoneboy.com/fw1 for the following FAQ: Can't Talk to Translated IP
from Internal Net.
I think that'll explain your problem.

Cheers and good luck,
Olaf

I have checked out everything I have received so far.

I have the local.arp file in %systemroot%/fw/state.
I have the static route in the os.
I have stopped and started the service, twice.

I can ping the number from an external location, just not internal.  Just to
clarify, what I want to do is ping from an internal, unregistered number to
an external, registered number that is natt'd back to the same internal,
unregistered lan my orig. request came from, just different machine and ip.

I am trying to ping an internal machine by its nat'd public address and get
no reply.  Is this possible with FW-1.  Here is my setup

FW-1 4.0 sp1
Win NT

Router  -  public address  - Firewall  -  DMZ unreg. addresses
                                 |
                               internal
                        unregistered addresses

For instance:

internal address is 10.10.10.10  nat'd to 111.111.111.111
>From machine 10.10.10.11  ping 111.111.111.111.  Get time out on all 4 tries

I know I can ping private address directly but for testing I need it to go
through the firewall.

Thanks for the help
