Cisco Firewall :: 5510 8.4 And ICMP

Sep 19, 2011

So I have my shiny new (used, but new to me) 5510 finally working and installed in my Dev network. I need to have icmp (ping and trace route) available from the inside network. I Google and found a few articles on how to do it. I tried modifying the class maps, but it looks like there are changes in the commands in 8.4 and the articles I found evidently were for 8.2 and lower. I tried doing it with access lists, again from examples and traffic stopped in all directions (not good) so I am back to being functional and how to do it in 8.4. Documentation seems sparse on the net with 8.4

Cisco Firewall :: ASA 5510 / PAT / ICMP Echo Outgoing IP

Apr 16, 2013

I have ASA 5510 with soft version 8.4(5) installed. There are two interfaces:
 
IP 1.1.1.1/24 - inside
IP 2.2.2.1/24 - outside
 
I have configured PAT, so network 1.1.1.0/24 gets NATted to 2.2.2.2 address. Everything works fine, except I can't reach 2.2.2.2 via ICMP from the internet.
  
X.X.X.X 2.2.2.2 Deny inbound icmp src OUTSIDE:X.X.X.X dst OUTSIDE:2.2.2.2 (type 8, code 0)
 
But I have configured an access list allowing ICMP from any to any: access-list outside_access_in extended permit icmp any any
 
Thus address 2.2.2.1, which is binded to outside interface itself, is perfectly reachable via ICMP.
 
I've got two questions:

1) Is there a way to fix it? It will be handy for diagnostic purposes.

2) is it possible to configure the secondary IP address on the interface on ASA? I've read, that there are some complications.

Cisco Firewall :: ASA 5510 - Allow ICMP From Three Blocks Of IP Addresses?

Jul 12, 2011

I have an ASA5510 running version 8.4. ICMP is blocked from the internet to the outside interface of our firewall but now our ISP is requesting us to allow ICMP from their network to the outside of our ASA. I need to allow ICMP from three blocks of IP Addresses?

Cisco Firewall :: ASA 5510 How To Limit Icmp To Just Single Host

Nov 1, 2012

I am working on an ASA 5510 on 8.4 IOS and need to know how to limit icmp to just a single host? What I would like to do is be able to PING from the Inside interface 10.X.X.X to host 4.2.2.2 on the Outside, but thats it no other host would be PINGable.I tried MANY different access-list statements but the only way I can get icmp out and working is using the "fixup protocol icmp" but then everything is PINGable and the ASA does not block anything.

Cisco Firewall :: ASA 5510 Allowing ICMP Unreachable On Outside Interface

Oct 25, 2011

I am having some issues with my ASA 5510 (running ASA 8.2) dropping ICMP unreachable-fragmentation-required-but-df-bit-set type messages coming in on the outside interface. I have the following entry in the ACL for the outside interface:access-list outside_acl extended permit icmp any interface outside and there are no other entries in that list that should take precedence and drop the packet. Pings from outside to the ASA work when this ACE is present and do no when it is absent so it is clearly taking effect. I see the following entries in the debug log when sending a large non-fragmentable packet (that would cause an intermediate router to send back this ICMP response) out to the internet through the ASa,As far as I can tell I am not running ICMP inspection; I don't want it to do any stateful magic here since the outgoing traffic would have been ordinary data from another protocol and would not have caused an outgoing ICMP connection to be built to match against.

Cisco Firewall :: ASA 5500 And ICMP Unreachable

Jun 27, 2012

Is it really the case that the ASA will not generate ICMP Host Unreachable messages for sub nets connected to any of its interfaces (in breach of RFC1812) as claimed here: [URL]

I'm investigating a situation where an organization uses ASAs to control traffic between different v lans in their internal production systems as well as Internet traffic.  They are having problems with internal load balancing because the ASAs do not (as currently configured) generate Host Unreachable packets.  Can this be changed in the configuration or not?  I have to say, if it can't then I'd urge them to find something else to route between their internal sub nets.

Cisco Firewall :: 2811 Not Allowing ICMP To PBX Through Same Interface

May 31, 2013

Attached is our network diagram showing the details of our remote office and the corporate side which are connected via private fiber. The workstation (10.10.102.84) can ping the 10.20.0.31 IP address of the PBX but not the .30 address and I know if we can’t ping it we can’t remotely manage it. The 2811 router, ASA 5510 and the 6509-E can ping both IP addresses on the PBX. The ASA logs the error "Denied ICMP type=0, from laddr 10.20.0.30 on interface inside to 10.10.102.84: no matching session" when the workstation pings the .30 address.
 
We changed the default gateway of the PBX from 10.20.0.2 to 10.20.0.1 (2811 router) and we were able to ping both IP addresses from the workstation but the SIP trunks from the Internet stopped working (they NAT to the .30 address). Because calls may be forwarded from the PBX to the corporate network (via IP phones) we will eventually need to change the default gateway to10.20.0.1 and still need the Internet SIP trunks.
 
My two questions are, how do we resolve the issue of pinging the .30 address from the workstation and then when the time comes how do we resolve the issue with the SIP traffic reaching the .30 address when we change the default GW of the PBX to the 10.20.0.1 address of the 2811 router.

Cisco Firewall :: ASA 8.2(5)26 - ICMP Echo Request Denied On Outside?

I'm having problem getting ICMP echo monitoring on outside interface to work. I've set: icmp permit host monitoring_station_adress outside but I still get:

%ASA-3-313001: Denied ICMP type=8, code=0 from monitoring_station_adress on interface outside. I'm trying to directly monitor ip on ASAs interface outside.
 
I have access-group tied to "in" direction on interface outside. Do I still have to put "permit icmp" rules despite the fact that icmp permit outside command is set?

Cisco Firewall :: PIX515 - Timeout ICMP / Access Lists?

Mar 29, 2011

I am using a Pix 515 with IOS 8.0(3).I have in my access list on the outside interface.......access-list outside_access_in extended permit icmp any 12.23.34.0 255.255.255.0 echo access-list outside_access_in extended permit icmp any 12.23.34.0 255.255.255.0 echo-reply.......in order to allow ping requests and ping replies into my inside network. This certainly works since I can ping the inside from outside and vice versa, but in the ASDM display of access rules, the hit count for these two lines is always zero. If I run 'show access-list', the hit count for these lines is non-zero.
 
Why doesn't the hit count show up in the ASDM gui display?Also, I have read that the PIX does not treat ICMP in the same way as TCP or UDP and there is no stateful behaviour towards ICMP.  However, if I set up a continuous ping from outside to inside and then disable the above access list rule allowing echo requests towards the inside, the ping continues whereas I would expect it to stop.
 
In the config there is 'timeout icmp 00:00:02' if there is no stateful connection for ICMP, why is there a timeout value for it?

Cisco Firewall :: ASA 8.4(2) Doesn't Respond To ICMP Echo On Ip Address With Port

Dec 13, 2011

In order to meet our requirements we had to configure PAT for TCP 80 on 2 external IP addresses to one internal IP in DMZ. TCP port 80 is being translated for both external IP addresses and it works as expected. However, since we have migrated to ASA both external IP addresses don't respond to ICMP echo requests generating following error:
 
%ASA-3-106014: Deny inbound icmp src outside:<Source IP> dst outside:<Destination IP> (type 8, code 0)
 
Previously we have been using Cisco router to achieve the same objective and it worked well.I have noticed that when I add "same-security-traffic permit intra-interface" to a configuration the message mentioned above stops appearing in a logs.
 
As far as I can tell ASA sends packet back through outside interface, despite the fact that appliance advertises its mac address in response to arp request for the same external IP address.Is there any way to make ASA realise that it should respond to ICMP echo requests on external IP addresses that have forwarding setup?
 
I do realise that ICMP would work in 1-to-1 NAT scenario, but we can't apply 1-to-1 NAT for 2 external IP addresses to point to one internal IP address.

Cisco Firewall :: ASA 5510 / Multiple VLANs Behind Single Firewall Segment?

Feb 5, 2012

I need to create a firewalled segment that not only separates hosts from general population, but also from each other.  The solitary confinement of firewalled segments.I know that I could create a bunch of sub-interfaces, one for each host or group that needs to be isolated, but I'd really rather not have to do that if possible.  1) It could become a management nightmare between ACLs and sub-interfaces and 2) it's a waste of IP addresses.s there any way that I can create a bunch of separate VLANs behind the firewall and have them all terminate at the firewall, using a single firewall IP address for the gateway?
 
VLAN 1 - hosts 1.1.1.5 and 1.1.1.6VLAN 2 - hosts 1.1.1.7
Firewall DMZ Interface - 1.1.1.1VLAN 3 - hosts 1.1.1.8 and 1.1.1.9 

This way, the hosts are isolated and can't talk to each other unless they're on the same VLAN.I'm working with an ASA 5510 running 8.2.4(4).

Cisco Firewall :: 5510 Major Flaw In Identity Firewall?

Nov 21, 2011

I have just configured identity firewall on our ASA 5510.I have 3 nodes that authenticates against Active Directory, using the Windows Server 2008 R2 builtin Network Policy Server: A laptop, a stationary PC, and a Android Phone. All 3 nodes are authenticated using the same user/password.
 
Now, in ASDM -> Monitoring -> Properties -> Identity -> Users, I can see two of the nodes with my user name attached to it, namely the laptop and the stationary PC.But not the Android phone.
 
Then it dawned on me. To set up the ADAgent properly, you have to apply 2 group policy entries. Unfortunately, those 2 entries are applied to the Computer Configuraton part of the Group Policy.This means that your COMPUTER has to be a member of your domain for USER IDENTITY to work.So my Android phone and other nodes not a member of the AD Machine Store will never be detected by identity rules, and can roam the network free.

Cisco Firewall :: 5510 - Transparent Firewall Installation Using ASA Version 8.4(3)9

May 14, 2012

I'm trying to install an ASA 5510 transparent firewall using ASA version 8.4(3)9 but I don't understand how traffic will ever pass through my firewall if both interfaces are on the same sub net(V lan) as the host and it's default gateway? The reason I'm doing this is were installing UAG (or Direct Access) and the UAG appliance need to have public IP's but still be behind a firewall (see attached diagram).
 
Looking at the documentation (which all seems to be for 5505's running 8.2) it almost seems like i need to have the transparent firewall 'in-line' to the ISP router?, but this router services another IP address range on another v lan for other (routed) firewalls (not shown on diagram) so putting it 'in-line' is not possible. Surely this can't be the case can it? If not how is it supposed to be cabled up and configured so packets go through the firewall?
