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.
Any detailed knowledge about Cisco ACS 5.1 and Windows AD interaction? I wonder why does Cisco ACS domain account must have permission to create/delete domain objects. This fact does really surprided me, because to my mind Cisco ACS only reads domain structure, and does not make any changes.
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?
I have a Cisco 5505 with a security plus license and but I can’t seem to create sub interfaces on it.

I have a production ASA 5505 that is working perfectly. I wanted to take a spare ASA 5505 and copy the running config to it so that I would have a backup unit that could be swapped out if the production unit went down.
Both units have security plus and running 8.2(1). The only difference is that the production ASA has 512MB of RAM while the backup ASA has 256MB. Also the backup has anyconnect and the production unit does not.
I copied the running-config to my tftp server and then copied the running config from my tftp server to the backup ASA as startup-config. After reload the device booted with an identical configuration to my production ASA, but after swapping out the units to test it, I have no access to the WAN or DMZ from my LAN. Swapping back to the production unit and all works as it should.
I printed out the running config from both devices and compared them line by line. They are identical except for the anyconnect line on the backup ASAs config file.
trying to configure our ASA 5505 (hence my request for the ASDM). However, I can go CLI if push comes to shove.
What I'm trying to do is allow a range of IP addresses on the inside interface (those which the DHCP server is doling out IPs which are XXX.X.XXX.14-140) to access email only (which is hosted offsite). They still need to access the file servers which are on the inside but nothing should be going out to the internet other than email.
I believe I have to create a Network Object which contains the IP range I wish to restrict. I can see where I add the Network Object but I don't know what the syntax should be to specify the address range.
I'm also not sure what the sequence of the ACLs should be and whether or not I can keep the default Access Rules in place. There are the two implicit rules: 1) Permit any traffic out to less secure networks 2) Deny any traffic to anywhere (which is superceded by rule 1, yes?)
To create an Access Rule like the one I desire, do I need to move the two existing rules down the list so that the new one will supercede both implicit rules?
I just upgraded my firewall to ASA 5505. Now, my original static ip address cofiguration is gone. Apperantly, Cisco went away from static ip address to something like nat (inside,outside) dynamic interface. how to create a static ip address under version 8.4? By the way, I am sharing what my configuration used to look before upgrading.
I'm trying via the ASDM to port forward http connections to a DVR for the purpose of viewing IP cams.I've tried via ASDM to create a public server but I'm not allowed to use my public IP address for the public Interface.I have only one public IP address available.Is there any way round this ? I would also like to know how I can enable NAT with PAT.I've tried setting the outside Interface for use with PAT but It keeps reverting to the setting for a range of external addresses.I'm not really used to the ASA cli yet , I'm getting there.If there's a workaround via the CLI , I'll take that route.
Just started using our ASA 5505 v8.2 (1) Trying to configure the ASA appliance to allow access into an internal resource (i.e want to be able to RDP into a system behind the ASA from the internet).I have used a static NAT:
When I view the logs it is reporting the following:Inbound TCP connection denied from 206.100.100.1 (external IP) to 100.100.100.2 /3389 flags SYN on interface outside.Been pulling my hair out with this one as I believe I have everything configured correctly.
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.
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.
I am trying to create host objects that I'll then add to network-object groups for use in ACL/ACEs.When I try to create a host I am having trouble adding the IP address.I then get an error saying the host name must start and end with letters or numbers and only contain letters or numbers. What do I need to do to create hosts from CLI?
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?
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!
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?
I have a home network using a 2600 and PIX515E, and unfortunetly I don't know how to set up ACLs. I read a few Cisco documentation but unfortunetly I am unable to grasp the concept of how to define them. Would anyone be able to give me a crash course on setting up ACLs?
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 old syntax that I am much more familiar with has been deprecated. On older IOS it would have been something like static (inside,outside) tcp 209.114.146.122 14033 192.168.30.69 1433 netmask 255.255.255.255 Plus an extended ACL to allow the traffic.I am trying to create a Static PAT to allow a host address to access our Network through an ASA. I have external address 209.114.146.122 that I want to hit the external interface on an obscure port (say 14033) and translate that traffic to an internal host address on port 1433.
I'd like to see some REAL LIFE comparisons of ASA firewall throughput (a bit like this one for ISR G2 Routers - [URL].
The reason I ask is that I recently upgraded a firewall from an ASA5505 to an ASA5520 on a small network where the only outside connectivity was a single 10meg Internet circuit with an IPSEC VPN (not landed on the firewall but on a router) to another site.
When I swapped out the firewall the users noticed a big improvement. The firewall is not doing anything out of the ordinary - no IPS or VPN, just standard state full inspection.
I have two cisco ASA 5505 devices and two cisco switches plugged to ASAs in each office. I need to create a VPN tunnel between two offices.
-Network behind the ASA1 in office1 is 192.168.1.0/24 with DHCP server – 192.168.1.10
-Networks behind the ASA2 in office2 are 192.168.5.0/25; 192.168.5.128/26 and 192.168.5.192/26
All computers in office2 need to get IPs from DHCP server 192.168.1.10. I have switch in office2 with 3 VLANS and I can assign computers from different subnets to different VLANs.How can I archive this goal? Should I assign 3 IPs for ASA2 inside interface (192.168.5.1, ...5.129, ...5.193) as a default gateways for each subnet? Should I put dhcp helper address 192.168.1.10 on the switch for each VLAN?
I have a newly aquired asa 5505 that I just set up to the bare minimum configurations. I followed a cisco paper on how to create a "remote access vpn" setup for ipsec. I can sucessfully connect and establish a VPN, but when I try to access an inside resource from the vpn address, the asa blocks it.
With an ASA 5505, i would l like to guide a sub network to an ISP and another sub network to the other ISP.i have 2 differents ISP.My major problem is the metric. I tried with access-list command to force the way out, but it seems that "metric" is stronger than "access-list".I don't know how to manage such LAB. is that possible with ASA 5505 appliance?

I have and vpn tunnel between a pix network (192.168.200.0/24) and an asa network (192.168.100.0/24); it's been running fine for awhile now but this morning i've come in an i can not access anything on the pix network, (mail, file & web servers). Each attempt to access results in a SYN timeout.

I have a Cisco ASA 5505 (version above) and I have someone that needs to SSH into a box behind the ASA. I'm having a few issues trying to configure this access-list and NAT. I've tried many combinations and clearly my IOS is not as good as I thought. What commands should I enter to accomplish mapping SSH from an outside network range to an internal host ?
I now need to configure an ASA 5505 for a small server farm. It's fairly straightforward:isp -> asa5505 -> internal servers,'m using static addresses -- no DHCP involved.VPN works; I can get into the internal network.pinging from the ASA to an external address works,However, I cannot get from a laptop connected to an internal port out to the internet, either using ping or typing an address in the browser.
I've been trying to configure a cisco ASA 5505 for my home network but I'm not having much joy with it. I've looked at countless guides, tutorials and followed the ASA setup wizard in ASDM. The Cisco 1841 is running sub-interfaces for my VLAN's.
I am having a problem trying to figure out how to add a new ASA 5505 to an existing network. My current network is:Cable Modem > Linksys > 48 port switch With multiple hosts residing on the 192.168.0.x network.Now i know that the ASA comes default with 192.168.1.1 on the inside interface and i want to change that to 192.168.0.1. I have tried to do this thru ASDM using the wizard and manually. Once i hit ok for it to write the config, it gives me an error that it didnt take. I then lose connection to the ASA and have to hard boot it to get it back.I am trying to do this without my external connection connected and i have a laptop connected to the ASA on port 0/2 with an IP address of 192.168.1.75.Do i need to connect my internet connection to it first and then run the wizard? I was hoping to get it configured for my existing network before i plugged in the internet connection to limit my downtime.This ASA came with 6.4.1 ASDM and 8.2 OS installed. i was able to upgrade the ASDM to 7.X but when i go to update the OS to 9.1, i get an error that i am not registered to use cryptographic software. Dont know where i need to register to get it?
