• 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?

  Can't say I've seen this before, but SSH is easy to do on the SAA.

  I recommend you to take out the first interface access list to see if that would be it.

  You have published only a partial section of the config, but make sure you have the SSH command with the address of the subnet that you connect from. Your config is no longer visible as I type this but try "SSH 0.0.0.0 0.0.0.0 outdoors. This allows all subnets access to the external interface. This command works as an access list to restrict connectivity to approved subnets. i.e. ' SSH 10.0.0.0 255.0.0.0 out "only allow hosts on the 10.x.x.x network to connect via SSH.

  Turn 'debug ssh' to see what errors are too.

  And, you can always remove your keys (related encryption rsa key) and rebuild their return (encryption key generate rsa 1024 mod gen). This will make your ssh client, I use PuTTY, think that this is a new feature and invites the OK to connect.

  Good luck.

• ASDM does not work in the external interface

  Hello

  I'm new to ASA. I have ASA 5510 and strives to enable ASDM access through the external interface. but is not working for me... not. I set up a public ip address on the external interface and activated the ssh and asdm. SSH works but asdm does not work. This is a test environment, so I have not yet set up an ACL.

• 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.

  Hello

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

• Access ASDM ASA on the external Interface

  We have three ASA5510s, each configured for ssh and http access to the Cel outside.  One of them has aaa users/passwords defined for both ssh and http.  I can access the ASA configured for aaa of the designated host allowed in the external interface normally using credentials of the aaa.  When I try to access one of the other two, they will refuse the enable login password.  The configured aaa ASA is version 8.2 with ASDM 6.21.  The other two are the two ASA version 7.0 with ASDM 5.07.  The ASA requires aaa is configured for https access?  How can I make these other two accept the ASDM login?  Thank you!

  If you do not have aaa then configured for ASSISTANT Deputy Ministers, you must use empty username and password enable.

  Also, you can use the "aaa authenticate http LOCAL console" and use a user/pwd to a private 15 user name to connect to the ASDM.

  To resolve what is a failure you can activate "debug http" and "debug aaa" on the SAA to see the reasons for which the user is rejected.

  I hope it helps.

• Secondary public network on the external interface

  We already have a range of public address configured on the external interface (213.XX. YY. ZZ/29). Our supplier we've assigned a new range of public addresses (62.XX. YY. ZZ/29).

  How can I configure this on the PIX?

  PS: as far as I know, the secondary addresses are not possible!

  Hello

  You don't need to configure anything on the PIX make you just as your ISP routes the new addresses to your PIX - then you can use the new address to what you like.

• Telnet on PIX with the external interface

  Is there a way to telnet in PIX Firewall through the external interface?

  SSH is a valid method to access the site, but I wonder if there is another way to do it. PDM is another tool for access and modification of the configuration.

  Any help will be useful.

  Best wishes

  Onur

  I'm pretty sure that Telent directly to the external interface of a PIX is not available. It is such a big security risk that it is not offered as an option.

  SSH is a much better way to go (even if it's only SSH1).

  You can probably VPN in your network and Telnet from inside.

  Good luck

• N3048 access to the Web Interface without OOB

  I recently had our switch replaced by RMA and have access to the web interface via oob. I'm not sure how to access ports and other subnets and want to access the web interface of the server room outside. It's probably something very obvious, but I don't have the original switch to check the configuration. Any help would be appreciated. Thank you.

  You can use in-band or oob access to administration from inside or outside the server room.  The port of oob is a completely separate network used for management only, but you can also use a port in the Strip management.  By default, VLAN 1 is usually used in the Strip to transport of management traffic.  If you set an IP address on VLAN 1 you should also be able to manage from this IP address.  Measures would be to define the IP address on VLAN 1, ping ping to test connectivity, remote and then use your browser to connect to the web INTERFACE.  You should be able to use the same username/password that was used for the oob port.  Without a set of name of user and password, the web INTERFACE will not allow the session.

• 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.

• 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

  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.

• PC54x8 access to the web interface of WS2012

  Hello. We have a strange problem. Because we are not networking gurus, we use the web interface of the switches to manage them (instead of using the CLI). The problem is that when connect us to the web interface of WS2012, the browser (IE) freezes. We tried this on several machines of WS2012.

  Management of WS2008 R2 works without problem.

  Is this a compatibility issue with IE10 (WS2012) compared to IE9 (WS2008 R2) or something else? I tried to add the address IP for trusted sites, but that did not help. Unfortunately only the servers with WS2012 are connected to this particular switch, so we are unable to manage it more (from the web interface).

  Any ideas what could be the cause of this? The web interface requires Java? Given that we have not installed on WS2012 servers.

  Unfortunately I found no work around to get the software to work with IE10. The recommended solution is to use another browser, which as you've found, works very well. I believe that the idea is that in future updates that IE10 will be supported, but I don't have a roadmap on how that would be released.

• 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.

• Any camera regardless of the interface is available for use with the LabView interface.

  Hello

  I intend to go for some CMOS camera,

  but I have a huge doubt before buying, the camera of menttioned above is not anywhere in this list. Nor can I see any type being supported USB device.

  The question is

  1. is a camera regardless of the interface is available for use with the LabView interface?
  2. Can I build a VI to communicate with any device image and recording of camera and take the data?

  Any kind of help or advice is greatly appreciated... I have to buy a CMOS camera and begin to run.

  Thank you...

  Hello Virginia,.

  I am pleased that this information has been useful, one thing I wanted to mention is that USB 3.0 has its own standard USB 3.0 Vision which is currently not supported. If this camera is also Direct Show compatible then you will be able to acquire an image using IMAQdx and manipulate all the attributes that are published to the API Live Show.

  I hope that USB 3.0 Vision will be supported in the near future, and we tentatively announced for this standard of communication for the August 2013 Vision Acquisition Softwareupdate.

  See you soon,.
