Cisco ASA 5510 DMZ No ping from host inside to gateway

Hello everyone,

I can not connect to the internet or ping the gateway or the outside interface from my host in the inside network. 

These are my settings:

:
: Serial Number: xxx
: Hardware: ASA5510, 1024 MB RAM, CPU Pentium 4 Celeron 1599 MHz
:
ASA Version 9.1(7)32

On my host I have the settings IP: 192.168.97.5 NM: 255.255.255.0 GW: 192.168.97.1

 

In packet tracer it shows me, that the implicit rule is dropping the package, I already tried to create a rule, which is letting all traffic through, but it still did not work.

I will be very thankful for everyone helping me.

@AlessandroDP211 you need to configure NAT, example:

object network INSIDE
subnet 192.168.97.0 255.255.255.0
nat (INSIDE,OUTSIDE) dynamic interface

To enable ping from the inside to the internet

fixup protocol icmp

 You cannot ping the IP address of the ASA's outside interface when connected to the inside interface, that's by design. You can only ping through the ASA to a device on the other side of the ASA.

only config

inspect icmp
