Cisco Firewall :: ASA 5510 Object Groups / Creating New ACL

Jul 20, 2011

I have an ASA5510 where I have defined object-groups and then associated them with a specific ACL.  Our ISP is pulling their point of presence from where I live and I am force to move to a new ISP.  I am in the process of setting up another interface for the ASA5510 to connect to the new ISP.
 
My questions is can I create a new ACL lets call it new_access_in and use it with the same object groups that I have already defined?  I know that I can only have one ACL bound to an interface, and will bind this new ACL to the new interface I am setting up, but I wasn't sure if I could use the same object groups and connect them to a different ACL.  I really don't want to have to create new object groups if I don't have to.

Cisco Firewall :: ASA 5510 Object-Groups Not Working

May 9, 2012

I have an ASA 5510 and have just started using object-groups which are super handy in theory, but not working in reality. I have a service object-group with a mix of tcp, icmp, and udp ports. Let's call it Sample_Port_Group. I'm trying to apply it to my dmz_access_in ACL. Here's the line giving me problems:
 
access-list dmz_access_in extended permit object-group Sample_Port_Group 192.168.1.1 any
 
The asa throws up an error between 192.168.1.1 and any. When I put up a ? after Sample_Port_Group, it gives me the option of putting in an IP address, any, etc. When I put in a ? after 192.168.1.1, it only gives me the option of putting in an IP address.URL

Those posts gave me the impression my line was possible, especially the "access-list outsideacl extended permit object-group myaclog interface inside any" line, which is at the end of the 2nd article linked.

Cisco Firewall :: Using Object-Groups For Easy Maintain ASA 5520 Configurations

Sep 19, 2011

After reading the post titled "ASA 5520 nat access-list query for internet access" I realized the object-group command could and should be used to make a more efficient and cleaner configuration. My current environment is very small and straight forward consisting of one FTP server in the DMZ. Though the guide: [URL] is straight forward, my inexperience hinders me from seeing how to use the commands effectively. A summary of the configuration is at the bottom of this post
 
Question: How can I clean up my current configuration? I have two references to the same server, dmz-rdp and dmz-ftp, created for port forwarding ports 3389 and ftp through the outside interface. I can combine them into one object statement, right? for each port I want to forward through the outside interface?
 
object network dmz-rdp
host 10.10.10.4
nat (DMZ,outside) static interface service tcp 3389 3389

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

Mar 5, 2012

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 :: 5510 - Create Network Object For IP To NAT Through? 

Jan 30, 2012

I have recently upgraded my ASA 5510 to 8.3 code and honestly I am confused on the best and most efficient way to do many nat translations through it.  I have a group of about 100 IP's that need http/https/and sqlnet allowed through for our web farm.
 
I have a text file with the real and translated IP addresses and in 8.2 I could simply modify it and dump the thing in and make the NAT rules and access-lists.  Now with the new object based model I am having a hard time wrapping my brain around how to do this using as few lines of code as possible.
 
Do I have to create an network object for each and every IP i want to nat through?

We have Cisco ASA 5510, I am about to add another 2 Objectgroup network  groups on the firewall to our already growing list. Under this Object-group Network xxxx , we are planning to add about about 500 network-object host xxx.xxx.xxx.xxx . This objectgroup will then be applied to an ACL. Just wanted to know if thats possible - meaning addnig 500 hosts? If it is whats the limit?
 
Also are there any other things to keep in mind before i go-ahead with this huge object group?

Cisco Switching/Routing :: Object-groups In Access-lists On 3750X?

May 29, 2013

I have started to use ip extended access-lists on several 3750X-switches to filter inbound and outbond traffic on the VLANs. But it seems that the use of object-groups is not supported, is this correct? Is it really no way to group different ip-addresses into groups and then use these groups in the access-lists?
 
I am running sw version 15.0(1)SE2.

Cisco Firewall :: 5520 - Object-group With Network-object Containing IP Address Range

Apr 7, 2013

Does the ASA treat an object-group with a network-object containing a range of IP addresses as a netmask? For example, I can apply this configuration without the ASA throwing any errors though the configuration calls for a 'net mask':
 
object-group network test
network-object 192.168.0.0 192.168.63.255
?
network-object-group mode commands/options:
A.B.C.D  Enter an IPv4 network mask
sh run ob id test
object-group network test
network-object 192.168.0.0 192.168.63.255
 
I found that in the documentation it requires a netmask as oppose to a range. Is this a bug in the code? I am running code version 8.0(5)23 on a 5520. If this is not a bug how does the ASA treat this type of configuration when applied to an access list? When I ran a quick packet trace and denied access from that range it looks like the ASA doesn't read that configuration properly.

Cisco Security :: ASA 5510 Object-group And Range Option

Feb 6, 2013

I have 3 ASA 5510s; two of which are in production and the 3rd one is new. I inherited the two in production and was trying to configure that 3rd one using some of the existing object-group network statements.  The problem is that when I try to create a range of IPs in one of the object-groups; the range command is not available. Here is one of the statements extracted from one of the production ASAs:  object network REMOTE range 62.77.130.14 62.77.130.208.Both ASAs have the same image ver (asa842-k8).  Is there something that I am missing to be able to enable the range option on the new ASA?

Cisco VPN :: Creating GRE Tunnel Over ADSL Between ASA 5510 And 2901 Router?

Jul 6, 2011

I've been looking to see if its possible to create a GRE tunnel between a Cisco 2901 with 3 adsl WIC cards and a Cisco ASA.The Cisco 2901 is at our remote office and we have 3 adsl lines for resillience as they tend to go down alot.The Cisco ASA is at our Head Office sitting behind our ISP's managed router.
 
The desired end result would be to have three GRE tunnels, 1 for each DSL line terminating on the ASA at head office and use EIGRP routing protocol to move traffic across to another tunnel should one fail, and encapsulate all of that with IPSEC.

Cisco Firewall :: Object To Twice NAT Configuration ASA5505 8.4?

Dec 18, 2011

We have an ASA5505 that we need to enable hairpinning on.... In the old firmware versions, we used to be able to configure a public to private static mapping along with hairpinning by using
 
static (inside,outside) outside_ip inside_ip netmask 255.255.255.255
static (inside,inside) outside_ip inside_ip netmask 255.255.255.255
 
In 8.4, if I use object nat, the hairpin functionality works perfectly,
 
object network obj-insideip
  nat (inside,inside) static publicip
 
however, since object nat only allows a single nat statement, I was attempting to use a twice nat to enable the hairpin functionality, but have been unsuccessful in coming up with the right combination of parameters for the functionality.
 
nat (inside,inside) source static private_object public_object destination static public_object private_object
 
allows hairpinning to successully work from the same machine.  Meaning on any given host, I can ping itself using the private or public ip, but I can't get the right combination for hairpinning from any private host to another private host via the public ip.  Other combinations have yielded icmp responses, however, they specify the private IP as the source of the reply instead of the public ip.

Cisco Firewall :: ASA 8.4 Network Object NAT Ordering

Aug 19, 2012

There is something wrong with the ordering of our NAT-rules.We are running ASA Version 8.4(2)8 and the nat config is pasted below.
 
I want outgoing smtp-traffic to be translated to xxx.yyy.zzz.18, but instead it's translated to xxx.yyy.zzz.20 (the outside-interface address).The same goes for ftp-traffic, according to packettracer this is also translated to the xxx.yyy.zzz.20.
 
Ciscos manual states that static nat rules takes precedence over dynamic nat but that doesn't seem to work for us. [code]

Cisco Firewall :: 6509 - FWSM To ASASM Object Conversion

Nov 4, 2012

We are in the process of migrating to the ASA service modules on both our 6509E switches from our current FWSM. We have used the Cisco conversion tool and applied that to the service module. When viewing the context in ASDM we are unable to view the object names in the right hand pane.
 
On the FWSM I would see the following under Network Objects:
 
Network Objects
- JQ-Test
- JQ-Test2
- JQ-Test3
 
Network Object Group
+ JQ Group
      - JQ-Test
      - JQ-Test2
      - JQ-Test3
 
Now I have run the conversion tool and applied that to the ASA's I now get the following results.
 
Network Objects
- 10.1.1.1
- 10.2.2.2
- 10.3.3.3
 
Network Object Group
+ JQ Group
     - 10.1.1.1
     - 10.2.2.2
     - 10.3.3.3
 
I am aware that the naming convention on the ASA's are different to the FWSM as you can no longer use the "name 1.1.1.1 JQ-Test1" format but I was hoping that the conversion tool would do this for me.
 
Is there any way I can get the names of the object back without having to script something that takes the old FWSM format and convert it into an ASA format?

Cisco Firewall :: ASA 5520 - Create Network Object For Range Of Hosts?

Oct 25, 2011

I'm migrating our network objects from our current firewall to a new ASA 5520 configuration. I'm using ASDM 6.4 for configuration.
 
We have a range of IP addresses for hosts that we need to add to a firewall rule/ACL. In the previous FW software I could create an object that was a range of IP address. For example there is an object called emailservers that is defined as 192.168.2.25-192.168.2.50.
 
Is there a way to do a similar thing on the ASA 5520?
 
I can see how to create subnets, but in this case I only have a range of IP addresses, no subnet mask.

The default configuration shows the eth0 with no access vlan and interface eth1 with access vlan 2... does it mean the eth0 is in vlan1 ? (Nativ Vlan ) ???

The group is located in LAN zone, so a permission from one zone to another zone is needed i think, but i can allow the internet acess to that group Is there another way to get that , different from NAT ?

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?
