Solved: Packet Tracer (Implicit Deny) issue

Kemal Zuko · ‎12-26-2013

Hello,

I am trying to do a simple packet tracer on my ASA and this is what I am getting

ASA# packet-tracer input DMZ tcp 10.250.0.5 2234 10.250.0.6 22 xml

</result>
ASA#

The 10.250.0.6 deve is a router directly connected to the DMZ interface 10.250.0.5

However I am getting the reason for droped packet as (Implicit Rule) which I can see is only on the global interface.

I am permiting ip any any on that same interface as well.

How can I make this work?

The reson for this is I need my ASA to authenticate with TACACS server which is behind the 10.250.0.6 router

Collin Clark · ‎01-01-2014

It's just strange that TACACS can't be ping'd, yet traffic through the ASA is good.

What type of device is 10.250.0.6? Do you have access to it?

Hi Kemal,

Reading your post 2 things came in to my mind:

1. Why you use /30 mask on your firewall? With this mask you have only 2 useable addresses. One you're going to use for the firewall interface IP, second one for the router.

2. Packet tracer with specified same source and destination network will always fail even if you allow all the traffic and enable same security traffic. Devices communicating within the same subnet will not hit the firewall.

Unless this is just a typo and you should just change the destination IP in the packet tracer? What is your TACACS IP ?

Regards

Mariusz

Kemal Zuko · ‎12-27-2013

the reason I have a /30 between my ASA and my router is tat behind my router I have another IP scope for my LAN (10.250.100.128/25)

I am douing dynamic pat on the asa and the router for the workstations to get out

the ip address of the tacacs server is 10.250.100.142 I am getting the same packet tracer resoult with the other IP as well

Mariusz Bochen · ‎12-27-2013

Would you be able to post the config fot us?

Kemal Zuko · ‎12-30-2013

Hello

yes the config is below...

Hi Kemal,

Sorry, but I have few more questions

Can you see the 10.250.100.128/25 network in the routing table (learned by eigrp)?

Are you able to ping the 10.250.100.142 from the ASA's DMZ interface?

Can you please post the result of

packet-tracer input DMZ tcp 10.250.0.5 2234 10.250.100.142 22 ?

Regards

Mariusz

We can see that an ACL is dropping the traffic. Can you do another packet-tracer with detail?

What are you seeing in the logs on your TACACS server? Do you see authentication attempts fromthe ASA?

No I dont see any requests from the 10.250.0.5 (DMZ) to the TACACS Server

here are the only two logs I see on my Tacacs

I am puzzeld on how the above device can talk to the Tacacs Server but my ASA DMZ interface cant even Ping it.

Can you try this-

Remove-

aaa-server BiHTac (DMZ) host 10.250.100.142

Add-

aaa-server BiHTac (inside) host 10.250.100.142

key ********

Kemal Zuko · ‎01-01-2014

Negative

I now cant even log in using my local database

aaa-server BiHTac protocol tacacs+

accounting-mode simultaneous

aaa-server BiHTac (inside) host 10.250.100.142

key *****

aaa authentication http console BiHTac LOCAL

aaa authentication ssh console BiHTac LOCAL

aaa authentication enable console BiHTac LOCAL

aaa authentication serial console BiHTac LOCAL

aaa authentication telnet console BiHTac LOCAL

aaa authorization command BiHTac LOCAL

http server enable

http 10.250.0.2 255.255.255.255 inside

ssh 10.250.0.2 255.255.255.255 inside

ssh timeout 20

ssh version 2

ssh key-exchange group dh-group1-sha1

Collin Clark · ‎01-01-2014

When it was set to (DMZ) you were also using local creds to get in correct?

Kemal Zuko · ‎01-01-2014

correct,

now I cant get in via ssh or http on inside interface

The only access I have is via console

I removed the ssh and http configuration for DMZ
