• IKEv1 and IKEv2 session in ASDM monitor?

  Hi all, have a question.  I have a setup of L2L tunnel between two ASA (v8.4).  I used the wizard to put these in place and selected the default values of IKEv1 and IKEv2, thinking that he would choose one or the other.  The strange thing is that, now, I see a separate session between these ASA, for IKEv1 and IKEv2.  Both pass traffic.  This is expected behavior?  Should I disable IKEv1 to force only v2, since both are v8.4?

  photo attached to explain.

  If both versions are configured then two IKE tunnels will be established.
  

  I don't know if that this is expected behavior. On tune ASA the tunnel manager should try IKEv2 first and if it fails try IKEv1.

  There could be some problems in which one side would launch IKEv1 while the other is IKEv2 concurrency.

  It's something we can can be studied by the tunnel manager and the two Yves debugging.

  I think you might want to open a TAC case, then we can this check completely.

• Site to Site VPN between Cisco ASA 5505 and Sonicwall TZ170

  I'm trying to implement a VPN site-to site between our data center and office.  The data center has a Cisco ASA 5505 and the Office has a Sonicwall TZ170.  I managed to configure the two so that the vpn connects.  Each of the firewall I ping the IP Address of the internet firewall on the other side and a desktop computer I can ping the IP Address of the firewall internal datacenter but I can't carry traffic between private subnets datacenter and desktop.  Can anyone help?

  The config below has had IPs/passwords has changed.

  Mattew, obvious lack of education is the rule exempt from nat for your tunnel, your access list pixtosw is similar on this example, I assume that you have gone through this link, if it does not see the configs on both sides.

  Add the statement of rule sheep in asa and try again.

• Cisco asa 5505 and centos VPN server connection

  Hi all

  Please I want to set up a VPN between Cisco asa 5505 and centos server.

  Here's my senerio

  Thank you guys

  Apology, do you mean access remote VPN Client of hundred BONE for Cisco ASA 5505?

  If the remote access, here are the sample configuration:

• AnyConnect + possible PSK (pre-shared key) as under with cisco vpn client ikev1 and ikev2

  Is it possible to create a VPN Anyconnect of RA with just the name of user and password + pre-shared key (Group) for the connection, as could do for ikev1 with cisco VPN client? I am running 8.4.X ASA code and looks like tunnel-group commands have 8.2.X somewhat change. If you change the group type of the tunnel for remote access, now there is no option for IKEv2 PSK. This is only available when you choose the type

  I'm getting old so I hope that it is not in another complaint curmudgeonly on the loss of functionality. :)

  Many small businesses do not want to invest in the PKI. It is usually a pain to deploy, backup, make redundant, etc..

  But it would be nice to have a bit more security on VPN other than just the connections of username and password.

  If this is not possible, it is possible to configure the Anyconnect customer to IKEv1 with PSK and name at the level of the Group client?

  If this is not possible, WTH did cisco end customer VPN cisco as a choice of VPN connection (other than to get more fresh mail of license)?

  I really hope that something like this exists still!

  THX,

  WR

  You are welcome

  In addition to two factors, you can also do double authentication (ie the two using the user name and password). Each set of credentials can come from a Bank of different identities.

  With this scheme, you can can configure a local user name (common) with password on the SAA (think of it as your analog PSK) and the other be the AD user identification information.

• IKEv1 and IKEv2

  I have a router 2821 with multiple IPSec Tunnels on it.  I would like to replace it with an ASA 5510.  My hope is to share these stars with a minimal impact on the active Tunnels.  I have the details of each well-documented Tunnel.  My question or concern is in the configuration of Tunnels on the SAA.  I have to configure IKE proposals in IKEv1 right?  If I use IKEv2, my concern is that there will be compatibility problems with the remote end of the tunnel, or is functional IKEv2 with IKEv1?  If no, then, can I just all set up in IKEv1 and ignore IKEv2?

  Thank you in advance for any idea offered.

  Dear Eric,

  Both ends must be configured for the same version of IKE.

  So you can ignore the IKEv2 parameters, even to uncheck the option 'Enable' IKEv2 in the connection profile.

  HTH.

• VLANS with Cisco ASA 5505 and non-Cisco switch

  I have an ASA5505 and a switch Netgear GSM7224 L2 that I try to use together.  I can't grasp how VLANs (or at least how they should be put in place).  When configuring my VLAN on the ASA5505 it seems simple enough, but then on my switch, I thought I'd create just the same VLAN numbers that I used on the SAA and then add the ports that I wanted to use for each VLAN.

  Currently on my ASA, I have the following VLAN configured...

  outside - vlan11 - Port 0/0

  inside - vlan1 - Port 0/1

  dmz_ftp - vlan21 - Port 0/2

  Port of Corp - vlan31 - 0/3

  I need to do the same thing on my switch as well...  On my way, I'm a little confused as to how I need to configure the VLAN.  Below is the screenshot of web GUI...

  

  Note: Normally you can now change the VLAN ID (red), but in this case the default vlan (vlan id 1) may not be changed or deleted, you can does not change its settings.

  Tagged (green), Untagged (purple) and Autodetect (yellow) you must select at least 1.  I'm not sure how to in one place to tell my inner vlan (vlan1).

  I want VLAN1 ports 1-8 on my Netgear switch used alone to talk to interface/0/1 on the ASA5505 port.  I don't want to NOT port 9-24 able to talk to ports 1-8 on the Netgear switch ports OR 0/0, 0/2 - 0 / 7 on the Cisco ASA 5505.

  So, how can I configure my inner Vlan1 on ports 1-8 on the switch?  Do mark, UNTAG, autodetect them?  What about tours?  I've been a bit the impression that I would set up my VLAN on both devices, then trunk port 1 and dedicate this port on both devices to nothing other than the sheath and the security of vlan would then take the packages where they need to go.  Is this the wrong logic?

  Hi Arvo,

  If the port of the ASA is just part of a single VLAN (i.e. e0/0 single door 11 VLAN), this is called an access port. If the port of the ASA had to carry several VLANs, it would constitute a Trunk port.

  To access ports (VLAN unique), you must set the switch corresponding to be unidentified for port this VLAN individual. If you decide to configure a trunk port, then the port of the switch must be set for labelling for each of VLAN who win the trunk.

  For example, ASA I have:

  interface Ethernet0/1
  switchport access vlan 20
  !
  interface Vlan20
  nameif inside
  security-level 100
  ip address 192.168.100.254 255.255.255.0
  

  With the above configuration, the configuration of the switch would look like this (assuming the e0/1 port of the SAA is connected to 0/1 on the switch):

  VLAN 20 - 0/1 = untagged

  If instead you use a trunk port, the config would look like this:

  interface Ethernet0/0
  switchport trunk allowed vlan 10,20
  switchport mode trunk
  !
  interface Vlan10
  nameif outside
  security-level 0
  ip address dhcp setroute
  !
  interface Vlan20
  nameif inside
  security-level 100
  ip address 192.168.100.254 255.255.255.0
  

  Assuming that the ASA e0/0 port is connected to 0/1 on the switch):

  VLAN 10 - 0/1 = tagged
  VLAN 20 - 0/1 = tagged
  

  Hope that helps.

• Cisco ASA 5505 and comodo SSL certificate

  Hey all,.

  I'm having a problem with setting up the piece of Certificate SSL of Cisco AnyConnect VPN. I bought the certificate and installed it via the ASDM under Configuration > VPN remote access > Certificate Management > identity certificates. I also placed the piece of 2 CA under the CA certificates. I have http redirect to https and under my browser, it is green.

  Once the AnyConnect client installs and automatically connect I get no error or anything. The minute I disconnect and try to reconnect again, I get the "VPN Server untrusted certificates! ' which is not true because the connection information to be https://vpn.mydomain.com and the SSL certificate is configured as vpn.mydomain.com.

  On that note, it lists the IP address instead of the vpn.mydomain.com as the unreliable piece of this. Now of course I don't have the IP as part of the SSL-cert, just the web address. On the side of the web, I have a record A Setup to go from vpn.mydomain.com to the IP address of the Cisco ASA.

  What I'm missing here? I can post config if anyone needs.

  (My Version of the Software ASA is 9.0 (2) and ASDM Version 7.1 (2))

  Yes that's correct. technically, it will take you to EKU as keys to authenticate server who was a little forced in version 3.1. But eventually, he was taken away. If you get no error using the browser and ot only comes with the anyconnect client. Most likely, you do not have to configured values. I can confirm that if you can share the fqdn with me also, you can try the upgrade and check it out.

  Thank you

  There is no DMVPN on the SAA. All that you have configured, is not compatible with the ASA or something another DMVPN then. At least debugging shows that there are some EzVPN involved.

  The debug version, it seems that there is no communication on UDP/500 possible between devices. Maybe something is blocking who?

• Exempt NAT and in cisco ASA intervlan routing scenario

  Hi, I'm new to Cisco ASA. I did some study on Cisco ASA recently and you try to understand how it works.

  The chart above illustrates the architecture of network in my company (attachment). The two FW (5520, version 8.0) are configured with nat control and same-security-traffic permit inter-interface. I have a ping of device A to unit B (10.10.105.244 > 10.10.70.70/24).

  At FW 02, I added an inbound ACL (10.10.105.0/24 > 10.10.70.0/24) because of the difference in level of security between the input and output interface (SL 50 < sl="" 100).="" for="" the="" return="" traffic="" (10.10.70.0/24=""> 10.10.105.0/24), I only need to add a device nat exempted from the rules as I have it configured with permit same-security-traffic inter-interface. My understanding is correct?

  FW 01, I need to add an entry ACL (10.10.70.0/24 > 10.10.105.244). Without the rule, my ping will be unsuccessful. Can I know why I need to add this rule to incoming traffic, because same-security-traffic permits inter-interface is set to FW 01? Can I know why I have no need to nat exempt traffic (10.10.105.0/24 > 10.10.70.0/24)?

  Sorry for the long explanation. I hope to get clarification and to ensure that my interpretation is correct.

  Thanks for all the comments. Have a nice day :)

  Hello

  For your first question: ""I know why I need to add this rule to incoming traffic, because the same-security-traffic inter-interface permit is set to FW 01?".

  It probably has to do with the ICMP inspection. By default, ICMP traffic is not inspected by the ASA for the return of the device traffic B to the device will be dropped on FW 01. You must activate the ICMP inspection by adding it to the MPF on the SAA default configuration.

  For your second question: "I know why I don't not need to nat exempt traffic (10.10.105.0/24 > 10.10.70.0/24)"?".

  NAT-control does not affect the same security interfaces, i.e. the same security interfaces can communicate without NAT even if NAT-control is turned on (with some exceptions). See this link for more information.

  For IKEv2 configuration: (example config, you can change to encryption, group,...)

  -You must add the declaration of exemption nat (see previous answer).

  -set your encryption domain ACLs:

  access-list-TRAFFIC IPSEC allowed extended LOCAL REMOTE - LAN LAN ip

  -Set the Phase 1:

  Crypto ikev2 allow outside
  IKEv2 crypto policy 10
  3des encryption
  the sha md5 integrity
  Group 5
  FRP sha
  second life 86400

  -Set the Phase 2:

  Crypto ipsec ikev2 ipsec IKEV2-PROPOSAL
  Esp aes encryption protocol
  Esp integrity sha-1 protocol

  -set the Group of tunnel

  tunnel-group REMOTE-PUBLIC-IP type ipsec-l2l
  REMOTE-PUBLIC-IP tunnel-group ipsec-attributes
  IKEv2 authentication remote pre-shared-key cisco123

  
  IKEv2 authentication local pre-shared-key cisco123

  -Define the encryption card

  address for correspondence CRYPTOMAP 10 - TRAFFIC IPSEC crypto map
  card crypto CRYPTOMAP 10 peer set REMOTE-PUBLIC-IP
  card crypto CRYPTOMAP 10 set ipsec ikev2-IKEV2-PROPOSAL
  CRYPTOMAP interface card crypto outside
  crypto isakmp identity address

  On your config, you have all these commands but on your VPN config, you mix ikev1 and ikev2. You have also defined political different ikev2. Just do a bit of cleaning and reached agreement on a 1 strategy for the two site (encryption, hash,...)

  Thank you

• Cisco asa active multiple interfaces on a single switch without configuration of vlan switch.

  I was wondering if there is a work around on cisco asa to have 2 interfaces vlan on a switch. The reason I ask I have a cisco asa 5505 and a dell switch that does not support the configuration of VLANs. I set up 2 interface vlan on a cisco asa and when two interfaces are active my internet drops frequently. I was wondering if there is nothing to configure the asa cisco to make this thing work. Thanks in advance...

  Assuming that Dell switch at least linking several interfaces of the ASA to the Dell should translate all media spanning tree protocols, but a bet covering the tree blocking State to avoid a tree covering loop.

  If the Dell does not support tree covering weight then you would be in very bad shape each broadcast packet would be will loop indefinitely and cause what we call a 'broadcast storm. "

  One way is not good and the other real harm.

• Cisco ASA url filtering

  I have cisco ASA 5515 and it works fine. Now, I want to activate the url filtering so that I can filter websites such as facebook, youtube, torrents and so on. I don't have the license for filtering url, and in accordance with the document of cisco, he said that we have no need for this from the url filtering license. So how can I block them?

  Hello

  Yes, certainly, please visit this link:
