ASA 5505: Outside Interface Becomes Inaccessible

Greetings --
I've been having occurrences of my ASA's 'outside' interface become inaccessible from the internet side. AnyConnect users that are logged in get kicked out ... can't ping to the IP address ... can't ssh into the ASA. Internally, I can ping the IP address and I can ssh into the ASA.
The 'lockout' typically occurs around 1PM, 7:30PM, and 10:30PM. To get the 'outside' interface working again, I would have to log into a host machine on the LAN (via TeamViewer) and then ssh into the ASA and reboot.
Any ideas why the lockouts are occuring? Is it possible my ISP is shutting down the IP?
Below is the configs to the ASA:

Hi,
I guess if you want to temporarily set up a software to receive the logs on some computer you could even use Tftpd (you will find it easily through Google search) The same software can be used for multiple different purposes.
I sometime use it personally when testing different stuff on my home ASA.
It naturally isnt a real option if you actuall setup a separate Syslog server.
You wouldnt really need to add much to your logging configuration
logging device-id hostname
logging trap informational
logging host
Where is the name of the interface behind which the server is and the is naturally the IP address of the server.
Though the above would generate a lot of logging.
I am not even 100% sure it would log anything when you are facing the problem.
Best would be to also troubleshoot while the problem is there.
Can you confirm that you use the Internet connection through the ASA when you are accessing the internal host behind the ASA? I assume that the host connects from the LAN to the Internet which enables you to have a remote connection to the host?
If this is so it makes it a wierd problem as the ASA and your ISP can clearly pass traffic to and from your network since that remote connections is working even if there is other problems.

How do I block pings from the outside to the ASA 5505 outside interface?

I was asked to block pings from the internet to the outside interface of our ASA-5505 firewall. I found a post that said to enter "icmp deny any outside", however that does not do it.
I created an ACL to try and do the trick, also to no avail:
access-list outside_in extended permit icmp any any echo-reply
access-list outside_in in interface outside
access-group outside_in in interface outside
Anyone have a clue what I'm doing wrong? I'm not the firewall guy as you can tell. :/
Thanks in advance...
Block / Deny ICMP Echo (Ping) on Cisco ASA Outside Interface
Most networks that you protect with a Cisco ASA device, will probably want to deny ICMP (maybe not all ICMP types, but a lot of network admins will want to block ICMP Echo, etc.) on the outside interface. This will make the network harder to find through external enumeration, but not impossible.
ASA5505(config)#icmp deny any outside
You will deny ICMP on the outside interface, but if you include ICMP as a protocol in the default global policy map, you can ping from the inside to any host on the outside, and it will be permitted back through the ASA, as it knows about the previous ICMP “connection

You are allowing echo-reply, thus it will reply to a ping
try this ACL:
icmp deny any echo-reply outside

Input and CRC errors on ASA 5505 outside interface

All,
I see input and crc errors on my ASA 5505 eth0/0(outside) interface and packet drops. There is very slow connection though we have 20mb line. ISP also sees the issue on the Lan interface side. We have the speed and duplex configured same on both ISP and our end.
I am suspecting if this is Physical cable issue. Please suggest.

Hello Ravi,
This kind of issues CRCs/ Input Errors are tipically known as L1 issues so make sure you check the cable and if that does not make a difference change the port on each side to see if there is a difference.
Unfortunetly the ASA does not support the Time-Domain Reflectometer feature so we must do the test of L1 by ourselfs.
Can you clear the counters of the interface, test the changes provided and provide us some feedback?
Looking for some Networking Assistance?
Contact me directly at [email protected]
I will fix your problem ASAP.
Cheers,

ASA 5505 backup interface

Hello,
I have setup ASA 5505 with 2 ISP, named outside (primary) and backup, the scenario is if outside down, then backup will take over, it works now.
But it is not working when the primary connection cannot reach the gateway with the interface still up.
Is it possible when the primary connection cannot reach the gateway then backup automatically take over?
Thanks before..

ASA 5505 - Outside Outbound Bandwidth Issue

ZyXel DSL modem (10MB download and 768Kbps or so upload)
DSL modem is operating in bridge mode
Cisco ASA 5505 in routed mode with ten users behind the ASA. Nothing fancy about the ASA setup.
Each user relies on their own FirePass or Cisco VPN client (outbound, no configuration required in the ASA) continously from 8am to 5pm. Outlook and light application usage over the VPN only.
On Friday, 05/17/13, the outbound connections were working well. Latency was good throughout the day (less than 40ms to Google). On the outside interface, output bandwidth was less than 500Kbps (much less for large portions of the day!). Three users were using streaming Internet radio.
On Monday, 05/20/13, the outbound connections were working poorly. Latency was bad (170ms and higher to Google). On the outside interface, output bandwidth was remaining steady throughout the day between 800Kbps and 850Kbps. Occasionally, the outside output bandwidth would drop to 40Kbps, then 600Kbps and then back to 800Kbps or so. No user on Monday was uploading any large files, no cloud backup or anything of the sort. No users were listening to Internet radio.
On Monday afternoon, I shut down five client machines and the outside output bandwidth was still around 800Kbps.
On Monday evening, I stopped by the office after each user had left the building and checked the outside interface output bandwidth and it was between 0Kbps and 45Kbps (virtually no load). I verified that all machines were powered on, but the VPN clients were disconnected.
On Friday and Monday, for the outside interface, the input bandwidth was between 200Kbps and 500Kbps with occasional higher spikes when users downloaded something.
What could cause the difference between Friday and Monday? Is the DSL upload simply maxed out? If the DSL upload is maxed out, why did it work well on Friday when I had a greater demand on the connection?
Thank you

Hello Modulus,
Did you take captures on the outside interface or the ASA ( This to check what is leaving the ASA ) as you are using VPN clients traffic will go encrypted so you will not be able to determine what is the traffic used for but at least you might notice some extra-traffic (outside the VPN traffic) as this does not look right or normal,
Regards
Julio

Firewall Cisco ASA 5505 new interface license problem

Hi
I have one ASA 5505 with a Base License
The problem is when i want to use a new named interface the system says "With current License maximum number of named interfaces allowed is 3. Name cannot be set for this interface"
And the question is if with this base license the interface cannot be used or only cannot be named?

Hi,
The ASA5505 has with Base License the limitation of 3 Vlan interface of which 1 is also limited in access (shown by the above output mentioning DMZ Restricted)
For an interface on the ASA to operate it must have a name with the command "nameif"
If you already have 3 Vlan interfaces in use then with this license you wont be able to configure 4th Vlan interface without getting a license that supports more interfaces. I guess that would be the Security Plus license.
I know that this has come as a surprise to several users that have posted here on the forums. I too think that its a needles "feature" in the ASA to limit the use of the device in such a way.

ASA 5505 external interface dying

Hi,
We have an ASA 5505 ( version 9.1(2) ) that frequently stopped functioning ie the external interface refuses to pass any traffic , ASDM wont connect,etc.
The internal interface does continue to function and if we SSH into the unit and do a reload , everything springs back into life again.
What are the best steps to troubleshooting and finding a fix to this problem?
Chris

Hi Amrin,

Asa 5505 sub interface plus ports

I have never used 5505 I gave used higher firewalls and all of them can do sub interfaces normally we make sub interfaces and vlans are assigned to them I m trying to config 5505 can someone tell me how I can create sub interfaces ? As I saw few config and it seems that you config vlans like switch ??? Secondly all interfaces have to b part of vlan ? Ie outside which is g0/0 ....can I config it as normall routed port ?

The 5505 is configured nearly the same a a L3-switch. You configure the Vlan-interfaces and assign these to your switch-ports. The switch ports can be configured as access- or as trunk-ports (if you have a SecPlus license).
You find more on this topic on the Config-Guide:
http://www.cisco.com/c/en/us/td/docs/security/asa/asa84/configuration/guide/asa_84_cli_config/interface_start_5505.html

Cisco ASA 5505 - outside can't DHPC as router use same range

Hi
Im new to the ASA and is trying to setup at test net. The ASA is connected to my router on port zero using DHPC.
(Or i guess its not as the router use the same ip range as ASA does inside).
I tried to set a static IP in the same range (eg. 192.168.1.20) but then get the message "cannot overlap with the subnet of interface inside".
So I belive that is why it dont get a IP from my router - it does show up in the router DHPC table as 192.168.1.5 but ASDM home says outside "no IP address".
I tried to change the inside range of the ASA but if I change the inside IP i loose connection.
(Had to restore factory-default useing the console).
I guess I could setup another range using the console, but how?
How can I setup this test net?

If I need to save I did not. (I have not used the console before).
Found the: "write memory" and reload command.
I cant connect to the asa using ADSM-IDM Launcher (from PC connected to the inside lan).
It seems that the asa DHPC server does not work.

Asa 5505 transparent firewall issue

hi i am having uc560 with voice and data vlan and i am having 3560 layer3 switch and my network is working fine the dhcp for voice and data both are running in uc560.
now i add asa 5505 between uc560 and switch in transparent mode means from uc560 to asa 5505 outside interface and from asa inside interface to switch,
i conigured vlan1 -- inside and vlan 2 as outside in asa 5505
in my uc 560 data is vlan 1 and my voice is vlan 100.
when i connect my network with transparent mode firewall no dhcp amd no phones are working . but if i remove asa and i connect with uc560 to switch everything is fine.
is there anyway to work multiple voice and data vlan in asa 5505 transparent mode.

hi rojas,
here is my problem,
my internet and voice all connected in the uc 560 so wat i am doing i am connecting firewall outside to uc 560 trunk port and the from inside to my switch.
when i connec to my switch it is giving message inconsistant vlan and it is port is blocked. and my phones are not working.
my data vlan1 is 192.168.123.x
and my voice vlan100 is 10.1.1.x
and the firewall ip 192.168.123.3

Thank you one more time for everthing. It is workingin indeed
Reason why maybe sometimes I had some 'weird' results was because I had all devices connected to the same switch.Separtated all networks to a different switches helped.Anyway if you could take a look one last time to my configuration and let me know if it's good enough to deploy it on live ( only www for all , ssh restricted from outside, lan to dmz) .Thanks one more time.

Cisco ASA 5505 configuration

Hi,
I have configured cisco ASA 5505 but I can't get access to internet using my laptop connected to the ASA. I did not use the console but the graphical interface for the configuration. I changed the inside adress of the ASA and it is 192.168.2.1. From the inside I can't ping the material in outside and from outside I can't ping the laptop connected to the ASA.
Here is my configuration:

Thank you for your help

Hi Sylla,
The static route you have configured for Internet access needs to be corrected:
route outside 0.0.0.0 0.0.0.0 192.168.1.48 1
The next hop address should be your ISP's gateway IP address and not the ASA's outside interface IP. Currently, both are configured for 192.168.1.48.

ASA 5505 - L2TP over IPsec - Remote Address shows outside interface address

Using an ASA 5505 for firewall and VPN. We've enabled L2TP over IPsec to allow Windows clients to connect without third party software.
The devices complete the connection and authenticate fine, but then are unable to hit any internal resources. Split tunneling seems to be working, as they can still hit outside resources. Packet tracer shows tcp flowing freely between VPN clients (192.168.102.0/24) and internal resources (192.168.100.0/24). Even the NAT translation looks good in packet tracer.
I pulled up the session details for one of the VPN clients in the ASDM and under the IPsecOverNatT details, it is showing the VPN client's remote address correctly, but displays the local address as the address assigned to the outside interface (which the client is using to connect.) This seems to be the problem, as viewing detailed connection logs shows the internal resources trying to send packets back to the outside interface rather than the VPN client's assigned internal addresses.

Any ideas? The remote clients connect but when internal resources try to send traffic to the VPN clients, the packets are directed to the outside interface address instead of the local address assigned to the VPN client.

I have what I believe to be a similar issue. Site to site vpn is working well. That is site b can ping and send traffic to site A but Site A can not. Site B is a 3rd party vpn router. Site A is a Cisco 5505.
It appears that when the crypto map inserts the route into the routing table it shows the route via the outside IP of the outside interface and not the IP of Site B. in the crypto map I can see the proper ip address for the peer. I can't figure out why when it inserts the route that it uses the wrong ip address

ASA 5505 - Cannot ping outside natted interface

Hello,
I have a Cisco ASA 5505, the problem is I am not able to ping to outside natted interface (ip: 172.88.188.123 and 124 and 125) from inside network
Could someone help me to resolve this? I have looked for ASA documentation through the internet and still got nothing.
Thank you in advance

Do you have a diagram of yourt setup and a more detailed description what you want to do?
The public interface of your main ASA looks like you are connecting to the internet. In that case, the IP address for the client has to come from the ISP and not from your main ASA.
