I'm a complete beginner with Cisco Packet Tracer.
I somehow cannot ping inside my dmz for some reason?
Any help is appreciated.
Kind regards

Hello @jonasvanessen
some issues...
ASA interfaces (red circle) are with IP address (L3) and on their respective Switches facing these 2 interfaces your are in Trunk mode...
Also your Multilayer Switch (L3) has got no route !
Servers on DMZ have got Gateway 10.0.0.1....where is this address ? On ASA you have on DMZ interface 10.0.0.2 configured.

This is by design. You only can ping the interface that is near to you. If your device is on the inside network, you can ping the inside interface but not the dmz interface. If you are on the dmz, you can ping the dmz interface but not the inside interface.

are they use same security level ?
12-12-2023 05:59 AM
yes, just to make it easier i've put both on security-level 100, see the .zip

I can not open zip
If same level
Then add
same secuirty level permit intra interface
Same secuirty level permit inter interface

Hi M02@rt37,
Thanks for your detailled feedback. I tried to implement all the points from your input, but sadly failed in getting it to work. Nevertheless i guess you are right, i think i just lack some basic understanding in certain areas, in order to get it to work.
Thanks & Kind regards
