routing in an ASA configuration

Similar Questions

• Default route of Cisco ASA

  Hello everyone, I'm new to networking and the question I am about to ask is probably stupid enough to most of you here, but anyway...

  Question: -.

  If I want traffic to flow inside the interface on firewall ASA outside, a default route (or some kind of routing) always must be configured FIRST? before ACL or NAT?

  see you soon

  The ASA needs to know how to reach the destination. It the destination is a network directly connected on the SAA, so no additional path is necessary. But if it comes to a remote network, the ASA needs to learn the track by a protocol of dynamic routing or through a configured explicit route (which could be the default route).

  If you need an ACL depends on your configuration. By default, all communications from lower security level are allowed. The inside interface usually has a level of security of the external interface of 0 and 100. So by default, it will work without an ACL. But if there is an ACL inside interface, then this ACL must allow the initial traffic.

  And for communication to a remote destination outside you probably also need NAT configured.

• tunnel from site to site between router IOS and ASA

  I've combed through the configs on both sides of this tunnel 4 x now and the look of policies as they match. I applied the http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_configuration_example09186a0080094498.shtml note

  My crypto lsits access are good and my nat on the side of IOS are provided with a map of the route and look good. On the SAA traffic side on the side of the remote tunnel ASA is exempt from NAT. Each side already has a site to another tunnel configuration, so I added the appropriate lines to the existing cryptographic cards which include peers, transform set and match address 'access-list. The polcies crypto isakmp on both ends are compatible. I have attached some configs and debugs (from router IOS), but essentially the newspaper on the SAA starts with the phase 1 is complete and then routing not received notification message, no proposal chosen readings and then it goes to IKE lost the connection to a remote peer, connection, drop table correlator counterpart has failed, no match, the deletion and finally disconnected session reason lost service.

  Their other tunnel stay standing as well as the configuration of remote access vpn connection is good.

  I found a note that recommends checking any access security-list, so I removed the, but no luck, and a Cisco associated with a hub, but had a healthy logic

  The configuration of the router has the

  Make the router for this proposal

• I do not have "Firepower of ASA Configuration" menu in ASDM

  Hello

  I do not have "Firepower of ASA Configuration" menu in ASDM.

  I already configured IP to the management port 0/0 10.226.24.181 also to the 10.226.24.130 of the SFP Manager.

  I can ping 10.226.24.130 ASA CLI and have tab in ASDM (with https://No DC configured the button).

  You can see in attachment

  Help, please

  You have an ASA 5525 - X and the module of firepower is 5.3.1 - 152. To manage the power light module on that platform via ASDM requires the runtime current software 6.0 or later version (and your ASDM must be 7.5 (1.112) or later version).

  Reference: http://www.cisco.com/c/en/us/td/docs/security/asdm/7_5/release/notes/rn7...

  If you want to upgrade the module of 5.3 to 6.0 and you do not have fire power manager, then the way ahead is to reimage using the 6.0 system images and boot. This procedure is illustrated below:

  http://www.Cisco.com/c/en/us/support/docs/security/ASA-firepower-service...

  You need the images available here:

  https://software.Cisco.com/download/release.html?mdfid=286271172&flowid=...

  Expand the tree on the left and look under all versions 6.0 > 6.0.0. Use the files asasfr-5500 x-boot - 6.0.0 - 1005.img and asasfr-sys - 6.0.0 - 1005.pkg.

  After getting it to work, you should also update further the the latest version (currently 6.0.1).)

• What virtual router goes with what configuration

  When close you a configuration creates a virtual router on the host computer, in some cases they are side by side in the list.  But sometimes the virtual router is set up far down the list of the configuration.  My question is how can you know what virtual router goes with what configuration?  I end up having to look at what data store its on and cross-references it with this organization.  Then I look everyone in the configuration for the combination.  Does anyone have a better way to know this?

  Alan

  Go to the vCenter and choose display "models and virtual machine.

  You should be able to expand the folders to see exactly where each configuration is set up, and routers should be stored with them.

  Don't forget, not to play with stuff from here... it was just suppose to look at the pretty ^_

• Router IOS Cisco Anyconnect ASA configuration

  Hello

  Could someone give me some advice if I can use a Cisco 1812 to connect to a Cisco ASA5512X using Anyconnect. The question we have is that some remote offices may be given fixed IP addresses...

  Thank you.

  AnyConnect cannot be used because there is only one solution-client-software and non-integrated IOS as the EzVPN client.

  You can use dynamic cryptographic cards already offered on the ASA with a card standard encryption on the router, or you configure remote EzVPN on the router and on the SAA EzVPN server:

• IPsec VPN site to site between router problem Cisco ASA. Help, please

  Hello community,

  I'm stuck in configuring VPN site to site between ASA (OS 9.1) and router Cisco IOS (IOS 15, 2 - 4.M4)

  Attachment is router configuration and ASA. I also include the router debug output.

  It seems that the two parties must isakmp missmatch configuration, but I have already disabled the KeepAlive parameters. I also turn off PFS setting on both sides. But it does not work. I have no idea on this problem.

  Please help me. Any help appreciated.

  Thank you

   
   

  I didn't look any further, but this may be a reason:

   crypto map mymap 1 ipsec-isakmp dynamic dyn1 

  The dynamic CM must always be the last sequence in a card encryption:

   no crypto map mymap 1 ipsec-isakmp dynamic dyn1 crypto map mymap 65000 ipsec-isakmp dynamic dyn1

  Try this first, then we can look further.

• Can the NAT of ASA configuration for vpn local pool

  We have a group of tunnel remote ipsec, clients address pool use 172.18.33.0/24 which setup from command "ip local pool. The remote cliens must use full ipsec tunnel.

  Because of IP overlap or route number, we would like to NAT this local basin of 172.18.33.0 to 192.168.3.0 subnet when vpn users access certain servers or subnet via external interface of the ASA.  I have nat mapping address command from an interface to another interface of Armi. The pool local vpn is not behind any physical interface of the ASA. My question is can ASA policy NAT configuration for vpn local pool.  If so, how to set up this NAT.

  Thank you

  Haiying

  Elijah,

  NAT_VPNClients ip 172.18.33.0 access list allow 255.255.255.0 10.1.1.0 255.255.255.0

  public static 192.168.33.0 (external, outside) - NAT_VPNClients access list

  The above configuration will be NAT 172.18.33.0/24 to 192.168.33.0/24 when you go to 10.1.1.0/24 (assuming that 10.1.1.0/24 is your subnet of servers).

  To allow the ASA to redirect rewritten traffic the same interface in which he receive, you must also order:

  permit same-security-traffic intra-interface

• Routing with Cisco ASA 5520 VPN

  I have installed IPsec vpn remote users in the Cisco ASA 5520 using RADIUS in my main network. Works very well. I have a site to my Cisco ASA5520 tunnels going to other sites, some of the tunnels have Cisco ASA and some have SonicWalls. I wish that my users VPN remote IPSec to be able to navigate in these tunnels is a site to access remote subnets attached to these tunnels. Do I need to use a combination of routing and the ACL? Or can I just use ACL only? Or just use routing only?

  Thank you

  Carlos

  Hello

  The key to set up here is the two ACL of VPN L2L end points that determine the 'interesting' traffic to connect VPN L2L. You will also need to confirm that the connection of the VPN Client is configured so that traffic to the remote sites have sent to the connection of the VPN client. There are also other things that you should check on your ASA plant

  Here most of the things you usually have to confirm

  • Set up 'permit same-security-traffic intra-interface' if it is already present in your configuration
    • This setting will allow connections to form between the hosts that are connected to the same interface on the ASA. In this case, applies because the VPN client users are connected to the interface 'outside' of the ASA and also remote sites are connected to the ASA to "external". If the traffic between the remote VPN Client and VPN L2L sites will be to enter and exit the same interface
  • You will need to check how the customer if configured VPN connection. Split or full Tunnel tunnel
    • If the connection of the VPN Client is configured as Split Tunnel then you need to add all the networks from the remote to the Split Tunnel, so that the connections between the VPN Client is transmitted to the ASA and from there connections VPN L2L
    • If the connection of the VPN Client is configured as full Tunnel, then there no problem that all traffic is transferred to the Client VPN connection all its assets
  • Define the VPN pool in the ACL of VPN L2L
    • You should make sure that the pool network VPN Client is defined in the ACL that define 'interesting' traffic to connect VPN L2L. So, you need to add the pool VPN VPN L2L configurations on the sites of Central America and remote control
  • Configure NAT0 / NAT exempt for remote VPN Client to L2L VPN Site traffic at both ends of the VPN L2L
    • You must ensure that the NAT0 / exempt NAT rules exist for the VPN Client for Remote Site traffic. This will have to be configured on the SAA "outside" interface. Format of configuration varies naturally a bit on the ASA Central his software level.

  These should be the most common things to set up and confirm for traffic to flow between the VPN Client and Remote Sites

  Hope this helps please rate if yes or ask more if necessary.

• is it possible to create a tunnel my router to my ASA 877 VTI

  Hi all

  I woulke would like to know is possible to create a tunnel VTI my router 877 to my ASA, rather than create a cryptomap on the router?

  see you soon

  Yes, you can

  I forgot to add that it is possible during the ezvpn configuration where the 877 is a remote client and a server Asa

• I can't access my web router from Firefox 4 configuration interface. It doesn't let me enter a password with the white of the username (as specified by the manufacturer of the router). Is there a solution for this?

  Since the update for Firefox 4, I can't access the configuration of my router (http://192.168.x.x) page. When you are prompted for the user name and password, Journal of Firefox in window does not accept an empty username field (the router does not require a user name, only a password and it is the default password). If I click OK, the entry of password just happens again. It works fine in other browsers. Is that what I can do about it?

  I had this problem too and by disabling the option "Tell sites I don't want to follow" the set under Options-> advanced-> browsing.

• modem router WAG120N wireless security configuration

  I use modem router wag120n but is confused abt how to set up wireless security of it is. Security Wireless Configuration recommended in tutorial given here is very different from what is given in my page of configuration routrs.

  I don't know how to manage the key renewal option. If I leave as 3600 seconds does that mean that I have to enter my device a new key wireless connected to the router after every 1 hour?

  Well well with firmware linksys/cisco security gateway wireless configuration seems even that is mentioned in the link provided: http://www6.nohold.net/Cisco2/ukp.aspx?pid=80&app=vw&vw=1&login=1&json=1&docid=7b0d8344c5524f75a8d5b... . But if in case it looks different let it me know what exactly what you see in the configuration page.

  Group key renewal determines how many times your group exchange key. The renewal time should not be too short or too long. The default is 3600 seconds.

  You don't have to deal with the renewal of key. It happens automatically. Customers do not lose connectivity, just the key for the changes of the connection. You won't notice. The longer the interval longer guarantee the link (in theory) as a striker who wants to break the encryption key has less time and less data to work on...

  But once again: it does not affect customers wireless connected. It's all past automatically just as it happens when the connection is established in the first place.

• Installed new router Netgear R6100 not configured now no wifi dell studio 1745

  I bought a new router and configured the wireless via my wifi. Everything worked well. Back on my laptop and nothing. I checked bios, enabled via the Device Manager and reviewed the mobility, but it is greyed out and won't let me turn it on. I have updated drivers by connecting directly and still no wifi. I appreciate all help you and I'm ready to do its utmost to return wireless. I also did a system restore before without success until I updated the driver. Thanks for any help possible.

  I found this driver download Dell Quickset and it let me activate my wifi. Thanks for your advice if this happens again I'll do as you say.

• Cannot access my router through the Explorer configuration page

  I need to do a port forwarding on my router. My internet connection works (even if she falls occasionally) and I can also connect to other computers on my network. However, I cannot access my router through IE page (I get a message saying: page not found). When I go see the map in the options Vista network, the router is not displayed and when I clikc on "See the whole map", I get a message saying that Windows cannot detect any computer or devices.

  My connection to the router is connected, and it is a WRT54G Lyinksys. Any ideas how I can see my router or go to its page layout? Another thing, I went to CMD and the ping command returns a default gateway 192.168.1.1, which is what I have my using the address of the webb page.

• Differences of router QoS and ASA

  Hi, I recently tested the QoS on an aid and 876 IPSEC tunnel and managed to limit participation effective and output rates using QoS on the router between two hosts.

  This made me think to try it on a SAA. I tried this on a SAA without success, but he also says in aid, it cannot be applied to the 'exit '. Is there a difference in the implementation of QoS between a router and ASA?

  Update - I had it at work but only when I use it all the traffic everything. If I select say 192.168.55.20-> all IT does rate limit.
