ASA5506X Help - Cannot connect to the ASA FirePOWER Module

Need some assistance with the new ASA-5506X for my home network.  For some reason, i can no longer access the FirePower module via the ASDM.  ASDM starts to load at stops at 17% (Initializing FirePOWER communication).  Here is the error:

Cannot connect to teh ASA FirePOWER module.  Check that it is correctly configured and on the network.  It is also possible that the management address is being translated by NAT.  Please verify the IP address/Hostname and port.

This unit has been challenging to say the least for a non security guy to get going.  Very little documentation on the 5506X is out there.  Here is what i'm trying to follow:

I have a 3560GC connected to interface Gig1/2, right now it's a very simple config using VLAN1 & the IP address of  I wanted to get the basic configuration working before i tried to introduce any complexity

Could really use some help

Your interface m1/1 also needs to be connected to the internal switch on the same vlan as your gi1/2.

The FirePOWER module can only use the physical management port for its IP communications directly to the rest of the network. Otherwise you can only access it via the internal dataplane as you do when you session to the module from ASA cli (or redirect the traffic via the service-policy for inspection).

Thanks Marvin, i left that out that it is also connected to the same switch on the same VLAN (i only have one vlan for now), however something is up with that port.  I kept wondering why the m1/1 interface was down/down...  I moved to a different port & all is working now...:o)...

Now onto some additional advanced settings.  I was originally thinking i would make the ASA be the default gateway for each VLAN.  My thinking was mark/map Guest traffic to a lower security level.  I wanted to get the basics working before moving on. 

Found the thread about the 5506 isn't a switch & doesn't support VLAN's but i'm going to try Subinterfaces to see what i can get working...:o).. Bridge groups could also be an option, just have to play around with is.

Subinterfaces should be fine for what you describe.

Bridge groups would mean moving to transparent mode.

Hello Dear Friends,


I am installing and configuring a New ASA 5506x, I have a little issue, I cannot connect to the sfr module If I connect in a diferrent subnet, I can ping, I can access the ASA via ASDM, but cannot access to the SFR.
If I am in the same subnet connect successfully.

When I try to connect to the ASA using the ASDM in of the ASA loggin I see the atacched log.

Any help will be appreciated.


Thanks in advance.

The sfr module has its own routing table and needs to have a default gateway set that tells it how to reach the external devices it communicates with.

The information you have given us doesn't tell us enough to be able to give a good suggestion as to what might be wrong.

If you could provide a diagram with the ASA interfaces, sfr address and its gateway as well as your client PC location, it would help. 

Hi Marvin,


Thanks for your quick response. Sorry for the previous post, I was in a hurry when I wrote that.

I attached a diagram with description of the issue.

If you need more information please let me know.

Thanks in advance.

Sergio Garrido

I agree with Gary's post.

Since you have an inside router, you would be better setting it's interface address in the subnet as the gateway for your sfr module.

Ok, I will do this change this afternoon. I will let know the results in briefly.

Thanks for your time and help.



Hi Gary and Marvin,


I fixed my issue following your suggestion.

Thanks you very much.

As per the Quick Start guide:

Note: If you want to deploy a separate router on the inside network, then you can route between management and inside.  In this case you can manage both the ASA and ASA Firepower module on the Management 1/1 with the appropriate configuration

Have you created that route?


Hi Gary,

Thanks for your reply.

I have a EIGRP process between the outside router, ASA and Inside Router.

The routing configuration between those three device works fine, only I have issues to manage the sfr module from other subnet through the ASDM.

Attached de diagram to get the topology and the issue.

Best regards,

Sergio Garrido

It is working. Thanks.

Hi Gary,


I have this problem too, but for me, everything are reachable to each other like the DC, ASA and SFR. I observe on your "show network" command, it specify that the management port is 8305. When I do "show network" it state below

===============[ System Information ]===============
Hostname                  : Sourcefire3D
Domains                   :
DNS Servers               :
Management port           : 443

Management port is not 8305 but 443. I also paste here the logs from DC.

I used windows 7 and installed esxi. inbound and outbound port on 8305 are open already.

I use firefox in linux.  I could only see the status tab in asdm.  I fired up a windows VM and IE showed the tabs.  I would like to see firefox work since IE is not available on linux. 

It looks like ASDM uses port 443.  Defense Center uses port 8305. 

I would like to have a Protect license over a Control license but that's me.  5 dmz's is a massive improvement over the 5505.  The professionally built SF solution with a reasonable home license subscription price would save me time building the in-line open source solution.  This is one of the few things I've seen that can catch the latest malware.
