• Network for access to the external interface inside

  Hey,.

  I have an ASA5520 7.2 (1) I have a few probs with - which is something I struggle with that.

  I'm trying to hit a website of a host on the inside network that is actually hosted internally, but decides the static NAT would focus on the external interface of the firewall.

  Now I can see the TCP built, translation occurring at a port on the external interface, this port high dialogue to one of the static electricity would be addresses on the external interface, then that's all. There are no more entries in my journal in regards to the connection and I get not syn on the internal web server is so the connection is not back in.

  IP address outside 222.x.x.9 255.255.255.248

  IP address inside 192.168.87.1 255.255.255.0

  Static NAT to Web servers: -.

  public static 222.x.x.10 (Interior, exterior) 192.168.87.5

  access lists access... :-

  list of allowed inbound tcp extended access any host 192.168.87.5 eq http

  Access-group interface incoming outside in

  Everything works fine when creating a global internet address - just not when address from inside and dynamic PAT is performed to the original address.

  Here's a capture session by using the following access to capture list inside and outside interfaces simultaneously

  permit for line of web access-list 1 scope ip host 222.222.222.10 all

  web access-list extended 2 line ip allow any host 222.222.222.10

  on the INSIDE interface (nothing is connected to the outside) (ip addresses have been replaced by nonsense) - but address 222 is would take into account the interface static and the other is on the internal network.

  316: 19:14:02.900206 192.168.87.10.2275 > 222.222.222.10.80: S 2029971541:2029971541 (0) win 64512

  192.168.87.10 is my client is trying to connect

  Someone of any witch hunt, which is stop this function work?

  All networks are directly attached and there is no route summary ancestral anywhere.

  I hope you guys can help!

  To my knowledge the ASA supports only hairpining on a VPN tunnel. The security apparatus does not allow traffic that is sent to an interface to go back in the direction of what she received.

• Can I connect an external keyboard for Portege A100?

  Portege A100 laptop can be used with an external USB keyboard? If so, is it important that the brand that I use? I finally convinced my wife to learn typing, but the keyboard of the laptop is not the easiest keyboards to learn.

  Hello

  Of course, it is possible. It s no matter what brand you use, but the connection is important.
  It must be an external USB keyboard because the A100 protégé supports only this interface for the connection of the keyboard

• 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.

• 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.

  Help, please

  Yes, if your external interface is mapped to y.y.y.y, then you will be not able to ssh to x.x.x.x as it will be pass on to y.y.y.y.

  You can change the static 1 to 1 to the port for each particular port address translation you need sent to y.y.y.y.

  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.

• WebVPN - no external interface connectivity

  Hello

  I have configured WebVPN on a router 1811W running IOS 12.4 (11) XW5, and even if the gateway is located directly on an external interface, port 443 seems filtered to the clients that connect through this interface (inside the interface, the traffic is allowed). What can I do to force the router to listen for incoming connections on the external interface (as it is supposed to)? I have no firewall or ACL that can potentially interfere with the VPN.

  Thank you!

  It comes to you main road

  IP route 0.0.0.0 0.0.0.0 FastEthernet0 10 track 123

  You backup route

  IP route 0.0.0.0 0.0.0.0 Dialer0 20 track 124

  If you try Dialer0 access from the outside, you return traffic passes through FastEthernet0.

  You have to 'Local ACB' for the correction...

• 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 a VPN 3005 cause multiple IP addresses on the external interface?

  Nice day

  Can a VPN 3005 cause several IPS on an external interface?

  I expect to use it in an environment that has 2 ADSL connections to an internet service provider. For the sake of the exercise, we could call them ROUTER1 and ROUTER2.

  We have a few VPN we always want to spend by ROUTER1 and some VPN we always want going through ROUTER2.

  Is this possible?

  Thank you very much

  No, not possible, sorry.

• PIX - Polo or not in function external interface used

  I'm still digging into that, but need not NAT all traffic begins inside for 2 of my low-security interfaces (dmz1 & dmz2), but have the same traffic PATed at the address of the interface if it goes on the external interface.

  I use nat (inside) 0 0.0.0.0 0.0.0.0 for the necked traffic that goes inside to dmz1 & dmz2. Then, this prevent me to put in another statement of nat [like nat (inside) (1 0.0.0.0 0.0.0.0)] as causing an error message saying the nat statements overlap. Makes some sense.

  It looks like a "static (inside, outside) interface 10.1.1.0 netmask 255.255.255.0" would be the ideal solution. But I get an error message "Invalid netmask interface option" when I try to enter that. So, who should not be able to address groups. It also won't let me do a static unique to the address of the interface, so that's going to not steal even though I was ready to toss around all the guests individually.

  I was hoping that static control let me to overload all inside responds to the address of the external interface when the data is out the 'external' interface, while the "nat (inside) 0" Let me NAT not nothing will dmz1 & dmz2, but not dice. "»

  Any thoughts on what I'm missing here? It must have a way to do.

  Thank you!

  Have you tried that?

  Let's say you have:

  192.168.0.0/24 inside

• 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

• 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
