• Change the IP address of the external Interface

  I need to change the IP address of the external interface remotely.  I have SSH in to the ASA plan and make a change.  I can't be there to make this change, since the site is out of State.  There will be problems?  The current configuration is

  interface Ethernet0/0
  nameif outside
  security-level 0
  IP 66.102.7.22 255.255.255.248

  The new IP address will be 66.102.7.18 255.255.255.248.  Also, is this the right syntax?

  interface Ethernet 0/0

  no address ip 66.102.7.22 255.255.255.248

  IP 66.102.7.18 255.255.255.248

  Thank you.

  Diane,

  If you access the ASA via its public IP address on the external interface, and if you change this IP address, you will lose communication with the ASA.

  It's better if you can make the change from the inside.

  If you need to change remotely, you can change the IP address, and then try the SSH connection to the new IP address.

  However if a problem occurs, you cannot access the ASA.

  The syntax is correct.

• EA6500 multiple IP addresses on the Internet interface

  I have verizon fios business with 5 static IP addresses and am set up for ethernet wan. I can use EA6500 as the router instead of use the own router to Verizon, but I can't understand how to assign every 5 static IP on the internet interface addresses. I have already affected the first IP address in the Web interface, but don't see a way to add multiple IP addresses internet interface or NAT section where I can create static NAT.

  Is it still possible with EA6500? If so, how?

  I don't think it's possible, given that the router support 1 address static IP at a time.

• MULTIPLE ADDRESSES ON THE EXTERNAL INTERFACE IP

  Hi all

  We put in place a number of ASAs for use with corporate VPN. When remote users connect using anyconnect they can hairpin on the Internet from Headquarters and must assign a public IP address for this purpose. To avoid people getting the same public address every time they go to the internet, we want to set up a pool of public addresses which will be awarded at random to the user of the VPN. Also, for their incoming connection requests, we have a ddns that solves a unique ip address for incoming connections. So, in summary clients connect to a single IP address on our ASAs, then hairpin at the internet and receive a public IP address from a pool. Look at us a few options to do so, but would appreciate any suggestions as to how best to achieve this goal.

  Thank you

  Hello

  It seems to me that the order of the chosen one NAT IP address of the NAT pool is random. I tested on my home with a pool of public addresses small ASA5505.

  I don't know if there is difference between different levels of Software ASA or rather the NAT configuration format. Since the 8.2 (and below) and 8.3 format (and more recent) is completely different.

  If we guess you configure NAT pool for VPN Client users connected to the ASA then configurations need you so

  Software of 8.3 and above

  permit same-security-traffic intra-interface

  object-group, network VPN-POOL

  Description the user VPN address Pools

  object-network 10.10.10.0 255.255.255.128

  object-network 10.10.20.0 255.255.255.128

  network of the PUBLIC-POOL object

  1.1.1.1 range 1.1.1.254

  interface of VPN-POOL PUBLIC POOL dynamic NAT (outside, outside) after auto source

  8.2 software and below

  permit same-security-traffic intra-interface

  NAT (outside) 200 10.10.10.0 255.255.255.0

  NAT (outside) 200 10.10.20.0 255.255.255.0

  Global 1.1.1.1 - 1.1.1.254 200 (outside)

  Global 200 (external) interface

  I don't know what is the amount of your user, but I guess you don't such a pool of important public addresses for users. The configurations above also contain a dynamic PAT when the NAT pool runs out.

  Is that what you're looking for?

  Hope this helps

• Can a single button cause multiple targets, based on the value of the point?

  I have a button on a form and based on the value of an element, when clicked, pages must be accessible. Is this possible to do? If so, any ideas are greatly appreciated.
  
  Request Express 3.1.2.00.02

  It's pretty simple to do using conditional branches. Create a branch to the place of the appropriate branch (for example on submit: after treatment...) for each target page and series PL/SQL Expression condition for each branch:

      :request = ''
  and : = 
  

  its replacement by < button_name >, < nom_element > and < item_value > with the values appropriate to your application (and change the '=' in the expression of the agenda if some other condition is used). The integrated attribute REQUEST contains the name of the button that submits the page.

• VPN client with counterpart on secondary ip address on the public interface of the router

  Hello

  On our office LAN, we have a Linux server than it hosting a VPN connection to a remote client.

  Do this to ISAKMP card on our Cisco router port connections to the internal ip address of the Linux host.

  However, we now want to allow our users to establish VPN connections to our local network using the unit of Cisco VPN Client.

  Of course, this would present challenges, as the ISAKMP our router port is mapped through an internal host.

  So, we tried to set up a secondary ip address on the router and VPN clients to connect to that.

  What we see in our newspapers is as follows:

  Phase 1 is very well established, and the VPN Client prompts the user for a user name and password.

  Authentication of the phase 2 starts, but the router says it's is not to receive a proposal of hash of the client.

  185 12:18:06.943 09/03/11 Sev = Info/4 IKE / 0 x 63000014
  RECEIVING< isakmp="" oak="" info="" *(hash,="" notify:no_proposal_chosen)="" from="">

  (in this case, where x.x.x.x is the secondary ip address on the public interface)

  After that, the Phase 1 SA is removed and the connection fails.

  My understanding is that the Phase 2 negotiation takes place with the ip address assigned to the client in Phase 1, which suggests that the problem occurs because the client communicates with the main on the interface ip address, and no secondary ip address.

  When remove us the mapping of port isakmp and the VPN client to connect to the primary ip address, everything works fine.

  Question:

  It is possible to establish 2 router VPN Client uses a secondary ip address?

  If not, is there some way I can implement the port mapping so that it occurs, the connection comes from a specific ip address?

• Static and VPN on the external interface

  Hello

  Can someone tell me if it is possible (and if so, how) do vpn enabled on the external interface and to have something like:

  public static x.x.x.x interface (indoor, outdoor)

  IE: I have two addresses ip - one for the router an e0 on the pix. I create a static and lists of access to allow inbound http/https server inside but I also want to allow vpn hit e0 and work. My configs work if I use an ip address 3 for the static, but not if they share. I can imagine that the static method takes the vpn traffic before the pix can use it OR maybe as the pix has no route to the now (due to the static method) that it cannot answer?

  Hope I'm making sense

  Thanks for the time spent on this

  see you soon

  Andy

  I think you want something like this:

  public static tcp (indoor, outdoor) interface http 10.10.10.10 http netmask 255.255.255.255 0 0 (where 10.10.10.10 is your web server)

  public static tcp (indoor, outdoor) interface https 10.10.10.10 https netmask 255.255.255.255 0 0

  access-list 101 permit tcp any host x.x.x.x eq 80 (where x.x.x.x is your IP interface)

  access-list 101 permit tcp any host x.x.x.x eq 443

  Access-group 101 in external interface

  It will be useful.

• VPN; list of access on the external interface allowing encrypted traffic

  Hi, I have a question about the access list on the external interface of a router 836. We have several routers on our clients site, some are lan2lan, some are client2router vpn.

  My question is; Why should I explicitly put the ip addresses of the client vpn or tunnel lan to the access list. Because the encrypted traffic to already allowing ESPs & isakmp.

  The access list is set to the outgoing interface with: ip access-group 102 to

  Note access-list 102 incoming Internet via ATM0.1

  Note access-list 102 permit IP VPN range

  access-list 102 permit ip 192.123.32.0 0.0.0.255 192.123.33.0 0.0.0.255

  access-list 102 permit ip 14.1.1.0 0.0.0.255 any

  access-list 102 permit esp a whole

  Note access-list 102 Open VPN Ports and other

  access-list 102 permit udp any host x.x.x.x eq isakmp newspaper

  I have to explicitly allow 192.123.32.0 (range of lan on the other side) & 14.1.1.0 (range of vpn client) because if I'm not I won't be able to reach the network.

  The vpn connection is not the problem, all traffic going through it.

  As far as I know, allowing ESPs & isakmp should be sufficient.

  Can anyone clarify this for me please?

• VPN client and ssh to the external interface of the ASA

  Hello world

  I was testing clientless ssl in my lab at home.

  When you're connected via vpn without customer, I am able to ssh ASA outside interface, but when I use ssl vpn only I can't ssh to the external interface of the ASA.

  Need to figure out how I can ssh to the external interface of the ASA using clientless ssl vpn?

  Concerning

  MAhesh

  Mahesh,

  When you are on clientless SSL VPN to your customer is not limited routes of the Internet, isn't being NATted etc. If ASA is set to allow ssh from outside, then the VPN SSL without client user is no different from any other.

  A the user SSL VPN full tunnel can have any or all of these factors at play. One of them can cause the impossibility to access the ASA outside interface via ssh. I see the configuration to tell you which one (or more) is to blame.

• Multiple Crypto cards on simple external Interface

  Hi, I got the following encryption card configured on my ASA5505 to allow Cisco IPSec VPN clients to connect from the outside:

  crypto dynamic-map SYSTEM_DEFAULT_CRYPTO_MAP 65535 pfs Group1 set

  Crypto dynamic-map SYSTEM_DEFAULT_CRYPTO_MAP 65535 value transform-set ESP-AES-128-SHA ESP-AES-128-MD5 ESP-AES-192-SHA ESP-AES-192-MD5 ESP-AES-256-SHA ESP-AES-256-MD5 ESP-3DES-SHA MD5-ESP-3DES ESP-DES-SHA ESP-DES-MD5

  outside_map card crypto 65535-isakmp dynamic ipsec SYSTEM_DEFAULT_CRYPTO_MAP

  outside_map interface card crypto outside

  I'm now trying to set up a map of additional encryption - a static configuration to establish a tunnel with Windows Azure services. The configuration, they gave me is:

  Crypto map Azur-crypto-map 10 correspondence address azure-vpn-acl

  crypto azure-crypto-card card game 10 peers XXX.XXX.XXX.XXX (hidden)
  

  card crypto azure-crypto-map 10 set transform-set of Azur-ipsec-proposal-set

  Azur-crypto-card interface card crypto outside

  However, when I apply this configuration, my Cisco IPSec clients can connect is no longer. I think that my problem is that last line:

  Azur-crypto-card interface card crypto outside

  that blows away my original line:

  outside_map interface card crypto outside

  It seems that I'm stuck with just picking one of the maps to apply to the external interface. Is there a way to apply both of these cards to the external interface to allow the two IPSec tunnels to create? We lack ASA version 8.4 (7) 3.

  Hello

  You can use the same "crypto map"

  Just add

  card crypto outside_map 10 correspondence address azure-vpn-acl

  crypto outside_map 10 card game peers XXX.XXX.XXX.XXX (hidden)
  

  card crypto outside_map 10 set transform-set of Azur-ipsec-proposal-set

  Your dynamic VPN Clients will continue to work very well that their statements "crypto map" are in the order of precedence / low in "crypto map" configurations (65535) and VPN L2L is higher (10)

  And I want to say with the above is that, where a connection VPN L2L is formed from the remote end it will be naturally VPN L2L configurations you have with the number of configurations "crypto map" '10'. Then when a VPN Client connects it naturally will not match the specific configurations of the number "10" and will move to the next entry and the match (65535)

  If you happen to set up a new connection VPN L2L then you might give him the number "11" for example and it would still be fine.

  Hope this helps

• VPN SSL from the inside on the external interface

  Hi all

  First of all I know that I can activate the SSL interface inside, but that's not what I need or want.

  Scenario:

  Several interfaces and VLAN on the SAA (running 8.0.5).

  SSL VPN configured and enabled on the external interface.

  Need to know if it is possible to access the SSL VPN from other interfaces directly to the IP address external interface, something like her hairpin.

  Possible a solution (if it exists) with or without NAT (I have public IPs on some interfaces).

  This will be useful for users who can connect any interface (inside, outside, or other) and with only a DNS record, I'll be able to manage everything.

  Concerning

  PS: Is DNS doctoring an option? The tests that I have done this does not work.

  Unfortunately, it is not possible. You cannot communicate with an ASA interface which is not directly connected through the firewall.

• Can a vDR device cause multiple backup destinations?

  I tried adding the shares network, adding that a different network share seems to remove the network share previously implemented at which the current backup operation is set.

  I want two shares of different network for a device with two jobs vDR, each backup operation goes to a different network share.

  How can I do this? 1.2.1 using latest version vDR.

  Alternatively, if each camera vDR can talk only to a single network share data store, I can set up another camera vDR.

  Thank you, Tom

  CIFS is not a recommended destination and can be much slower. If you want an accessible destination I would add a couple of NFS shares as network data warehouses. Then add a normal VMDK unit vDR. You can do several (more than 2) virtual machine backups but as I've mentioned before that you will incur the trouble to write the cbt file for each additional backup done.

  I'd do more simple a test you can against 2 or 3 small VMs. run multiple backups. Check the speed of the restoration. Decide if you can live with the speed of the restoration. I'm not sure that this is the most appropriate use of the vDR unit.

• How can I print a list of MAC addresses in the Airport utility?

  Hi-

  In our House, security Wi - Fi is obtained by listing the MAC addresses of machines allowed in our airports.  Make a list of these addresses used to be as simple as make a screenshot of the table in the Airport utility.

  Now, with MacOS 10.11.3 and Airport 6.3.6, the table in the network utility > Timed Access Control... > Wireless Clients no longer mentions the MAC addresses.  You can view them one at a time, but you cannot display them all at once.

  Is there a way - possibly with Terminal commands, or perhaps AppleScript - to display the names of the guests from the airport and MAC addresses in a kind of list?

  -Gil

  Apple has closed all utility of its utility... so now, it's the bare minimum and nothing more.

  You can buy tools of third-party network, inet, fing for your iOS devices and find all attached devices.

  Or you can buy a router to another provider and keep the most convenient airport for WAP than this OK functions.

  You can also export the configuration file... search in a text editor and remove MAC addresses... but there is nothing that even comes close to what decent average routers made nowadays.
