ASA 5512x No Internet Connectivity

All,

I am updating my 8.2(3) code for my new ASA5512 that is running 8.6(1) and am unable to get on the internet with my current configuration from the inside interface.

Information:

Outside: ***.***.33.11

Gateway: ***.***.32.9

Inside: 192.168.215.0 /24

dhcp 215.100 - 150

This should be VERY SIMPLE, yet the new NATting is killing me. PLEASE HELP.

Thanks,

Greg

ASA 5512x No Internet Connectivity

Hello,

Can you ping 4.2.2.2 from the ASA?

Add the following:

     object network any_net

          no  nat (inside,outside) dynamic interface

          exit

      nat (inside,outside) source dynamic any interface

Regards,

Julio

I added the code without success.

No, I have tried a ping to 8.8.8.8 as well as the gateway.

Gonzalo,

Hola, The fact that you cannot ping is probably because of this:

icmp permit any inside

There is an implicit deny under that, meaning it will block any icmp messages on the outside interface.

Do the following,

Clear config icmp

Show ARP (make sure that the Next hop mac address is ther)

Remove this (not because it is necessary, because it bugs me a lot)

-access-group inside_access_out in interface inside

-access-group global_access global

Try to ping the next hop again

Gather show xlate

After that is done, run a packet tracer like:

packet-tracer input inside tcp 192.168.214.2 1025 4.2.2.2 eq 80

And give us the result.
