Cisco Firewall :: ASA5505 NAT For Group Of Objects

Oct 4, 2010

My ASA5505 has an external address of x.x.x.13. We have got another 2 spare ip addresses: x.x.x.10 and x.x.x.11.We also have 2 internal hosts, which we need to provide with internet access using NAT. y.y.y.146 and y.y.y.70.
We recently updated our ASA to software version 8.3(1). I was thinking that I could do it using network objects and groups, but didn't understand quite good how this should be done.
The goal is to set up ASA in the way, that if either of the abovementioned 2 hosts will connect to the internet, it needs take one of 2 external addresses. All other hosts should use PAT through x.x.x.13.

Cisco Firewall :: ASA5505 How To Convert 3 Group Mac Address To 6

Apr 16, 2013

Recently i bought asa 5505 to practice for my exams and i failed to connect to internet since my internet provider binds IP and mac for every users and  supports only 6 group mac address (xx-xx-xx-xx-xx-xx) format. because asa 5505 has  3 groups (xxx-xxx-xxx) mac address they are unable to provide me the connection.So my question is how can i assign 6 group mac address to asa5505.

Cisco Firewall :: ASA 8.3 - Migration Changes Hosts To Objects?

Sep 24, 2012

I'm testing upgrading an ASA from 8.2.5 to 8.4.4.  During the the upgrade, it change all of my ACL host entries to objects.  But I noticed that the keyword "host" is still a valid option when creating an ACL.
I'm trying to understand why this change is made during the migration.

Cisco Firewall :: ASA 5520 Adding Network Objects Via CLI

Nov 3, 2011

I'm working with ASA 5520s. how to add network objects via CLI. I know I could easily do it using ASDM, but I like to learn the hardway first. How do I add the subnet mask for a network object when creating via CLI? [code] That sets up the hosts with IP addresses, but how do I add the subnet mask?

Cisco Firewall :: Recreate Objects In Groups After Migration To 8.3?

Feb 22, 2012

when I migrated the ASA config from 8.2 to 8.3, in all groups the group members has been replaced by the IP address object. However, the "name" for this object has been migrated, but there is the "object network name" configuration missing.
What I can do now is that I can open the new created object in the ASDM, search for the object with this IP address and then enter the object name I had before. When I apply the config, ASDM then creates the object and replaces all affected objects in all groups, by replacing the object group memeber "network-object host hostname" with "network-object object hostname".
Do you know if there exists an automated way, which checks all the groups for members "network-object host", creates the "object network" and replaces the "network-object hosts" with "network-object object" within the group? As long we have a lot of groups which contains partially > 50 members?

Cisco Firewall :: Can't Create Network Objects On ASA 5505

May 17, 2011

I have a customer an exisiting 5505 which connects to multiple sites for a site-to-site VPN.  This firewall was not installed by myself originally I have just been asked to take a look now.The situation is that we now need to edit one of the existing site-to-site VPNs to include the remote sites expanded network.  I have tried doing this through the ASDM and have found that I cannot add new network objects.  I have tried creating a new network object group and then added the new networks from there but I am completely unable to add the new objects.I believe a picture tells a thousand words in this case so I have attached some images which show the problem.  I have also tried going through the VPN wizard, this also does not allow me to add new network objects.

Cisco Firewall :: Number Assigned For Firewall-group On 6509 Significant

Nov 17, 2011

Is there any significance to the parameter "firewall-group" in the command

firewall vlan-group <firewall-group> <vlan-id>…<vlan-id>?
In other words is the series of commands
firewall switch 1 module 3 vlan-group 1,2
firewall vlan-group 1 100,101,102
firewall vlan-group 2 200,201,202
exactly equivalent to
firewall switch 1 module 3 vlan-group 3
firewall vlan-group 3 100,101,102,200,201,202
firewall switch 1 module 3 vlan-group 1,2,3
firewall vlan-group 1 100,200
firewall vlan-group 2 101,201
firewall vlan-group 3 102,202

All three of these options associate the same set of  vlans to the FWSM but using different groupings. As far as I can tell, these groupings have no functional significance either on the switch side or the FWSM side. These are simply three different ways of specifying exactly the same thing? Am I correct?

Cisco Firewall :: Users Behind ASA5505 Firewall Are Unable To Access Internet

Feb 24, 2011

I have a normal setup of ASA5505 (without security license) connected behind an internet router. From the ASA5505 console I can ping the Internet. However, users behind the Firewall on the internal LAN, cannot ping the Internet even though NATing is configured. The users can ping the Inside interface of the Firewall so there is no internal reachability problem. In addition, I noticed that the NAT inside access list is not having any hit counts at all when users are trying to reach the internet.

When i replace the ASA5505 with a router with NAT overload configuration on it, the setup works normally and users are able to browse the internet.

The ASA5505 configuration is shown below.

hostname Firewall

interface Ethernet0/0
description Connected To Internet Router

Cisco Firewall :: ASA5505 Can't Ping New Firewall On Inside Interface

Jul 14, 2011

I've recently upgraded my old firewall from a PIX to an ASA5505 and have been trying to match up the configuration settings to no avail. I have is that I can't ping the new firewall on it's inside interface, despite having "icmp permit any inside" in the running config. Secondly, the server I have on there ("Sar") can't connect out to the internet.I've included the ASA's running config incase anybody can see if something stands out. I have a feeling it's either not letting anything onto the inside interface, or there is no nat going on. Lastly (and possibly relevant), the firewall is actually going at the end of a vlan, which is different to the firewall's inside vlan number. I don't know if this is actually the problem because the server can't connect out even if connected directly into the firewall.

Cisco ASA 5505 - >Inernal LAN switch.
1.  Internet  is connected to Juniper Ge0/0/0  via /30 IP.
2. Juniper fe0/0/2 port is configured as inet port and configured the Internal public LAN pool provided by the ISP. And this port is directly connected to  Cisco ASA 5505 E0/0. Its a /28 pool IP address. This interface is configured as outside and security level set to 0.

From Juniper SRX, am able to ping public Internet IPs (

1. From ASA am unable to ping public ip configured on Juniper G0/0/0 port.(/30)
2. From ASA no other Public internet IP is pinging.
Troubleshooting Done so far.
1, Configured icmp inspection on ASA.
2. Used the packet tracer in ASA, it shows the packet is flowing outside without a drop.
3.  Allowed all services in untrust zone in bound traffic in Juniper SRX.
4. Viewed the logs when I was trying the ping in ASA. It says "Tear down ICMP connection for faddrr **** gaddr **

Cisco WAN :: 2821 / IP SLA Tracking Objects Dropping?

Mar 24, 2013

I use tracking objects aroung the organization where I work to monitor WAN and VPN connections and add/remove routes based on the state of the object.  I'm having 2 locations that are constanty going up and down and I've been troubleshooting and monitoring for the last few weeks without finding anything.  I've been incrementing the timeout for the SLA and it seems like this is working a little (less overall drops) but the drops still occur.  Our ISP reports no issues and we see no issues internally on the circuits.  Just out of curiosity could this be some kind of IOS bug or hardware malfunction?  The router logs are full of these:
Mar 21 16:18:33: %TRACKING-5-STATE: 2 ip sla 2 reachability Up->Down
Mar 21 16:18:38: %TRACKING-5-STATE: 2 ip sla 2 reachability Down->Up
Mar 21 17:24:14: %TRACKING-5-STATE: 2 ip sla 2 reachability Up->Down
Mar 21 17:24:19: %TRACKING-5-STATE: 2 ip sla 2 reachability Down->Up

The IOS version of the router I took these from is 151-4.M6 advanced IP services and it's a 2821 router.

Cisco WAN :: 800 Network Objects To Allow Management User IP

Aug 27, 2012

I'm trying to add an extended ACL (120) to an 800 series router (887) using Network Objects to allow the management user IP range full access to IP services and restricted access to email only for standard user IP range. However as soon as I apply the ACL to the outbound of my Vlan no matter what is in the ACL my PC looses internet connectivity. I've tried adding an explict allow for my IP address and still no access so I'm thinking possible a NAT issue, please have a look at my attached config and let me know what you think. Would I be better trying to control data flow with ZBF? I want to restrict standard users to email access only during the work day with web access and IM access after hours along with blocking all P2P programs for standard users at any time. Management group will have unrestricted access to all IP protocols. My original plan was to use time based ACL's!

Cisco VPN :: ASA 8.4 LDAP Group To ASA Group Policy Mapping?

Jul 31, 2012

I try to map LDAP Group to ASA Group policy following documentation:
This is a config for ASA 8.0. I would have expected it to work on 8.4 as well but I do run into problems. The mapping as shown in LDAP Debug and ASA Log will actually happen but it is overwritten by the "GPnoAccess" Group Policy configured locally in the Tunnel Group. From earlier works with RADIUS I would have expected the user specific Attribute to be "stronger"?
ASA Log:
AAA retrieved user specific group policy (correct Policy) for user = XXX
AAA retrieved default group policy (GPnoAccess) for user = XXX

Cisco Firewall :: ASA5505 Firewall Rule Not Blocking

Apr 1, 2013

I'm trying to troubleshoot an ASA5505.
The original goal was to block "Mumble/Murmur" (a voip app) traffic, which runs on TCP/UDP 64738, both inbound and outbound, except to a certain host (
However, when nothing I tried seemed to make a difference, just to troubleshoot, I decided to try blocking all inbound traffic.  I first disconnected ethernet port 0/0 to ensure that it was cabled correctly and the outside interface went down when I did.  That worked as expected, so I confirmed I had the right interface and it was cabled correctly.
I then applied a "any any deny ip" rule as the first element in the outside interface access_list, as you can see below.  However, it appears to have had no real effect and the hit count is very low (it should be astronomical).

Cisco :: Named Objects Or Object Groups In ASR 1000s?

Any way of doing named objects or object groups for ACLs on the ASRs? (1000 series in this case.) I'm setting up an ASR with a zone-based firewall and writing out all the addresses, ports and protocols for the ACLs associated with the various zones is creating huge, unwieldy ACLs in the config.

Cisco Firewall :: ASDM Access Through S2s Tunnel Group On ASA5510

Feb 7, 2012

For years now we've had an ASA5510 running an old version of ASA/ASDM (7.0/5.0) and couldn't access ASDM through a modern system with a recent JRE, so we didn't bother with this.
However, we've recently upgraded ASA/ASDM for purposes of adding failover and want to be able to access ASDM through our site to site tunnel. The site to site tunnel gives us access to the VLAN that the firewall is the gateway for, but not access to the firewall itself.
This side of the network is the subnet, and that side of the network is the subnet. I can ping devices on the subnet, but not the firewall, (not that I really need to) and devices can ping me back. I can access ASDM through RDP or ssh into a server on the subnet, but not directly from the subnet.
This is the current config relative to the subnet:
access-list trust_nat0_outbound extended permit ip
access-list untrust_cryptomap_600 extended permit ip


As far as I'm aware, the tunnel comes into the firewall through the untrust (public) interface, because that is the destination of the tunnel on the subnet side.
What am I missing here that would allow asdm access through the untrust interface for the subnet?
