ASA 5510 DMZ setup

Unanswered Question
May 11th, 2008

I tried to make ASA 5510 work as it mentioned in the Getting Started Guide that came with the ASA appliance. It is a basic DMZ scenario where I have a web server running on and outside interface on ASA is I followed all the steps mentioned in the guide. For step 1, I configured IP pools for Network Translation, For step 2, I configured Address Translations on Private Networks. For Step 3, I defined external identity of the web server that is And for step 4 , I provided http access to the web server.

The problem is when I connect a pc on a outside network, I was not able to access the web server. I could ping web server ( from ASA but not from a pc that is connected to outside interface. Is it a routing problem? Do I need to do something else?

I have this problem too.

Before I set up DMZ, I should be able to communicate from inside interface to outside interface and vice versa. My outside interface is on and inside interface is network.

Also from the documentation, I should see two vlan, one for inside and one for outside. But when I did

ciscoasa# sh vlan

I don't see any vlan.

don't assign vlans unless they are plugged into dot1q ports. if you dont' know what this means, you probably shouldn't do anything.

Thanks, but what are the commands that will assign vlan to ASA ports and show vlan information. This is for future reference.

Before implementing VLANs, you need to understand the licenses required for this

interface gig x

vlan x

nameif outside

security-level 0

ip address xx.xx.xx.xx

no shut

interface gig y

vlan y

nameif inside

security-level 100

ip add yy.yy.yy.yy

no shut
