topic Hello,I ran those exact in Network Security

Implicit rule blocking my outside network. Please help :(

JpetersonMonarch — Tue, 12 Mar 2019 08:04:08 GMT

Hello,

I'm new to ASAs but am nearly copying another config exactly as I'm learning it. What's going on is that my outside interface can send packets to 8.8.8.8 properly, but my inside network drops from the implicit rule. I've been desperately making changes, so I'm sure a lot of the config does not make a whole lot of sense.

My goal> Static IP for outside network

Inside network of 10.12.1.1 reaching the outside network.

Here is my running config:

Note: (( )) numbers are just static numbers from my ISP. I've deleted irrelevant information to save space. I do not have any VPN tunnel set up yet.

Result of the command: "show running-config"

Looks like you have an issue

Greg Smalley — Wed, 27 Jul 2016 15:38:50 GMT

Looks like you have an issue with NAT rules. Remove the following rules:


no nat (inside,outside) source static any any
object network obj-any
 no nat (any,outside) dynamic interface

!Add following 
object network LanNet
nat (inside,outside) dynamic interface

Thank you for the fast reply.

JpetersonMonarch — Wed, 27 Jul 2016 16:18:32 GMT

Thank you for the fast reply. I believe my ADSM wasn't updated fully so my settings may have changed a bit. I removed the static NAT I had set up and the obj-any interface. I believe I set up the LanNet modification correctly. I see the home screen on ADSM is receiving a lot of traffic, but I'm still having issues connecting to websites via Chrome. Sending a packet from outside to 8.8.8.8 succeeds but sending it from the inside interface is dropping at the implicit rule.

Sorry my formating got a

Greg Smalley — Wed, 27 Jul 2016 16:23:36 GMT

Sorry my formating got a little messed up on my earlier reply, I still see the manual NAT rule in there I wanted you to remove and then I wanted to add a new Auto NAT rule, we also need to make a slight adjustment to your LanNet network object. Try the following:

no nat (inside,outside) source dynamic any LanNet

object network LanNet 
 no host 10.12.1.0
 subnet 10.12.1.0 255.255.255.0
 nat (inside,outside) dynamic interface

We want NAT installed under the LanNet object (This is called Auto-nat).

If you'd like me to reset

JpetersonMonarch — Wed, 27 Jul 2016 17:16:32 GMT

If you'd like me to reset back to factory-defaults or anything like that, let me know. I'm very curious as to why this isn't shooting out to outside.

I am not seeing a problem

Greg Smalley — Wed, 27 Jul 2016 17:50:22 GMT

I am not seeing a problem when I use your configuration in my lab, my packets are going through.

Can you run the following command on the ASA? edit: I should note, run this from the # prompt not config.

packet-tracer input inside tcp 10.12.1.8 23232 8.8.8.8 80

Phase 2, type access list,

JpetersonMonarch — Wed, 27 Jul 2016 21:26:33 GMT

Phase 2, type access list, subtype result drop. Rule implicit rule. Result outside interface outside, output status up, output line status up, action drop

It works in my lab, the ACL

Greg Smalley — Wed, 27 Jul 2016 23:22:22 GMT

It works in my lab, the ACL that it hits is "access-list inside_access_in extended permit ip object LAN any" which is permitted:

Phase: 2
Type: ACCESS-LIST
Subtype: log
Result: ALLOW
Config:
access-group inside_access_in in interface inside
access-list inside_access_in extended permit ip object LAN any 
Additional Information:

Is your default gateway correct?

Perhaps you can post the entire packet-tracker, but this time also add "detail" to the end of the command?
