Cisco Security :: PIX Configuration To 5500 ASA NAT?
Aug 18, 2011
Our client ( a webhost, they have a lot of servers ) has a an older Cisco Pix, everything works fine with the PIX. They have a Cisco ASA 5500 with ASA version 8.3 , to replace the PIX. Upon migrating the PIX config to the ASA we are running into issues with Dynamic NAT. The static NAT entries are working flawlessly (there is a lot of them), however when Dynamic is enabled for the remainging hosts, outside communication works then drops off. The remaining hosts need outside access for updates. We have access lists set up but I dont se ehow that could cause a problem when the original ACL's were working fine with the PIX, they have not been altered.
The NAT config may be wrong or cluttered, have a look at the full NAT config.
The static NAT addressing is the same, example 207.11.129.65 will equal 10.10.10.65
we currently use a CISCO ASA 5500 Series Firewall model number ASA5510-SEC-BUN-K9.
we have a need to erase all the data from any flash memory on-board. This is to allow the firwall to be re-used elsewhere with a good degree of confidence that no existing data remains on the switch.
Our client have cisco 5500 Wireless lan controllers. They connect to core switch and other ports conenct to various switches on each floor. Then we have cisco AP 1300 series mounted on celing. I was reading that lightweight AP gets config from WLC as soon as they plug in. Need to know how the AP gets config from WLC switches?
Our requirement with that appliance is to do URL blocking and filtering.Are there any other options we can consider or is it SaaS only. Would have preferred Trend Micro, but don't this is possible with this appliance.Will content security be offered on the Cisco ASA 5500-X Series?At this time, content security services are not supported on the Cisco ASA 5500-X Series appliances. However, the ASA 5500-X Series Cisco Cloud Web Security ready. Cisco Cloud Web Security provides content security as a cloud-based software as a service (SaaS).
I have been searching but unfortunately not successful in finding appropriate documentation on how to configure the ASA such that a user using AnyConnect SSL VPN client is prompted for their username + AD credentials + RSA SecurID token (all three must be presented/entered by the user) in separate fields before the VPN tunnel is established. On latest version of AnyConnect (3.1) and ASA version 9.x on 5500-X.
I try to configure a Cisco 5508 Wireless controller and 25 Air-lap1041 to use as VoIP and data. I read documents, manuals, etc, but the AP doesn't charge the configuration, or not conect with the Wireless Controller, why? No Radius server present, only WPA security.
I try to put a static ip in the LAP, with lwapp or capwap command, (LWAPP/CAPWAP ap ip address direccion mascara) and the AP returns "You should configure Domain and Name Server from controller CLI/GUI." and i can't change the name of the AP (Command is disabled). [code]
Is it possible to restrict the Remote Access VPN to ASA based on the Source Public IP , if so how ? here I am not talking about the VPN-Filter under group-policy . I Want to restrict the access from specified source IP (Public IP)
Is it possible to regain the PSK from the security tab from a 5500 controller in clear text?I need to check the current used password without resetting it, but I fail to find the password in the configuration (CLI & web interface)Obviously I do have admin access to my controller.
saw that we can secure ripv2 via authentication (simple and MD5) ,i undertand that simple is not quite secure because we can see the plain text when capturing RIP packets
however even with MD5 i can see the authentication data (output of MD5) and i think hacker can copy it and paste it in one RIP packet that he will generate !! isn't it ? so how much MD5 is secure ?
I was given a 510 PIX Ver 6.3(1)to reconfigure but have no information on the existing configuration and need to wipe it clean and start over how can I do this to get back to the factory default settings. I have tried the "monitor>" but I don't know the IP address of the PIX interface.and am not sure how to do the setup for recovering the password.
We have had an ASA5505 for close to two years. About a year ago, we added a second ISP ("BOB") which became our primary and our old one (SBC) became our backup. I successfully modified the config for this and it's been working well.
Now we're changing our primary ISP to Comcast and getting rid of BOB, so right now we actually have 3 ISPs coming into our building.
I removed the BOB interface and routes, then added an interface for Comcast using an IP address from the range they provided as well as a static route to the gateway they provided - everything is analagous to the previous interfaces and routes, but it doesn't work. If I physically disconnect the Ethernet cable going to the Comcast cable modem, then the ASA does fail back to the SBC interface as expected. If I put the BOB interface & route back in there, it works again through BOB.
If I connect a PC to the Comcast cable modem and use an IP/Gateway they provided, the Internet connection *does* work. Using this same exact IP info in the ASA doesn't work.
Is there some other configuration item besides interfaces and static routes that I should be modifying? Is there some way I can dig deeper into the ASA to see exactly what is failing?
I save the configuration in the ASA 5505 using write memory or using copy run start but whe i unplug the power cord and plug it back in the ASA gets its factory default configuration.. then what i do is a copy start run to get the configuration active..
I have got a working 5505 running 8.3.1 firmware and 6.3.1 ASDM.I have now purchased a second unit and ensured that both units are running the same firmware levels etc.
I have via the ASDM created a backup of the working units configuration, and now i want to load this configuration onto the second unit.I have connected the consiole cable up to the second unit and tried pasting in the contents of the configuration file but no joy.I want to ensure that my configuration will work on this unit before i configure the two units in Active/Passiove configuration.
I used my Pix config to setup the ASA 5505.Everything seems to be right. I used ASDM to view settings and it seems right. I am missing something minor, but I am going blind looking at it.
I can remote into the network from outside, but internatlly I cannot get out of network. No internet or email is passing through.
i hav asa5520 i copying configuration from PIX to ASA5520 (7.2) everything working fine bt problem is that after sometime my DMZ interface losing connectivity ...
i just deployed Cisco NAC version 4.8.1 Virtual Gateway OOB on a LAN envieronment and on a WLAN envieronment, it works fine for some users , they can authenticate via the agent or web page, and then they are redirected to the access vlan, But for some other users in LAN and WLAN , when they try to authenticate via agent or web page the following error appears:
Invalid switch configuration-OOB Error:OOB client "mac/ip" not found.
I tried to find some pattern for the users but it dont match any pattern.
I have a problem exporting the config from a 1112 appliance.It does not boot up properly. GUI logon and authentication is not possible.I can console and SSH to it but the only thing i get is the commands below and nothing else.Could not chdir to home directory /home/admin: No such file or directory
I recently configured WCCP with a Sophos Web Filter on my network it works good but the problem I am having is I have two 5520s so I am directing the device to look at 2 different IP addresses and since the devices are in an Active/Passive failover. The problem is because the second device is in a passive failover it is not responding which is throwing connection errors to my Sophos device. I know you can have a single management connection for the ASA's but is there a way to have a single IP for the ASAs for the WCCP?
I'm having some issues configuring NAT statements on my ASA5505 which has recently been upgraded to 8.41.
I have a single dynamic IP on the outside interface of the ASA and would like all internal hosts to NAT/PAT to it. In addition, I would like to have several ports 'forwarded' to internal hosts, one of which is TCP/4343. With the current configuration all hosts are NATing to the external interface properly but the service running on TCP/4343 is not accessible from the outside. See command output below:
"sh run object" output: object network DrJones host 10.81.220.90object network LAN-10.81.220.0 subnet 10.81.220.0 255.255.255.0 "sh run nat" output: object network DrJones nat (inside,outside) static interface service tcp 4343 4343object network LAN-10.81.220.0 nat (inside,outside) dynamic interface "sh run access-list" output: access-list inside_access_in extended permit ip 10.81.220.0 255.255.255.0 anyaccess-list outside_access_in extended permit icmp any any echo-replyaccess-list outside_access_in extended permit tcp any interface outside eq 4343
I've noticed that many people have routers with NAT as part of their security configuration. What NAT is/does? Also, I entered the router's settings and went to Advanced > Firewall > NAT ENDPOINT FILTERING .There are 3 options specified for UDP/TCP Endpont Filtering; they are:
Endpoint Independent Address Restricted Port and Address Restricted
What are these options? I downloaded the manual for the router but it doesn't mention what NAT, Endpoint Independent, Address Restricted, and Port and Address Restricted are.
Side Note: I thought about setting up a secure connection using WPA2. Right not I'm using an unsecured wireless network. If I setup a new secure wireless connection using WPA2 will my current unsecured connection still be available?

I need to estimate the installation and configuration time of Cisco NAC (NAC Network Module spare for 2800, 3800 ISR) and Cisco NAC Manager(NAC Appliance 3315 Manager -max 3 Servers. There is some Cisco tool to estimate the installation and configuration time?
I am implementing wireless lan controller for a customer's site. This site uses Cisco WLC2112 and AIR-LAP1041. I configure via start-up wizard and WLAN security configuration. The client joining via WLAN seems to work fine, able to browse Internet. But when adding a shared printer or sharing files, the machine's unable to find the computer name. When test pinging, it replies when pinging by IP only. This is not happened when using a LAN wire.
I'm trying to configure the NAC Profiler with a 3310 CAS Collector. In the "Edit Collector" menú, it shows all the modules as "Running", except for the NetWatch module which shows a state "Invalid configuration file (missingInternalAddress)".
I configured the eth3 interface of the CAS as a monitor interface in the Profiler (see attached image), and I tested that the SPANed traffic actually reaches that interface from the access switch. I'm using software version 3.1.0_24 in both the Profiler and the Collector.
I have connected a 10BaseT device to a CISCO Catalyst 3560xPOE switch with dynamic port security. All seems to work fine when the distance between the two devices is closer then 200ft. When I connect to 10BaseT devices farther out near 300ft the response from the attached device is lost. It works ok on unmanaged switches at the longer distance. Is there a minimum response time from attached devices for dynamic port security to work properly? Is there any other explanation why it would work on cheaper switches, but not on the Port Secured Switch?
