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.
Federico.

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.

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.

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.

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?

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

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.

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.

I can't change the language interface of win vista
I can't change the language interface of win vista
Hello
Browsing the forum here it looks like there are a few options, you can try:
If the language bar is not listed in the menu toolbars, you do not have many input languages installed on your computer. You must add other languages using region and language in Control Panel. For more information, see Add or change an input language
This is an additional option of "Old GrayGary" with the link here:
http://www.techsupportforum.com/members/113412.html
Quick-Fix:
Do you have a language icon in your system tray? (If you switch between two choices of language installed / entry screen, the current selection must display in the system tray: for example IN English, JP for Japanese, etc.). Make sure that you have not chosen to "Hide inactive icons" in your bar spots Vista 'Properties' - or the icon can not be displayed. If you see such an icon, you should be able to right click on this icon and choose 'Restore the language bar' in the option dialog box.
Quick-Fix #2:
Since the language bar is a system setting, and the problem is recent, you might be able to recover your old settings using Vista System Restore utility - using a restore point out just before the language bar disappeared. You would probably go to Windows Update to reinstall all critical patches that have arrived since the time that the restore point was created originally.
_______________
Must neither of these approaches works, try to visit the region and Language Options in the Vista Control Panel.
Control Panel
Clock, language and region
Regional and Language Options
If you use different languages with your devices, you visit the "Keyboards and languages" tab and select "Change keyboard" - in the "text Services" and input languages window, the middle tab is "Language bar" - I think that the option to show or hide the taskbar is available here. If you use different languages for display only, you can go directly to the option "Change display language" from the regional and Language Options (and try the "Language bar" tab there).

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.

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.

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
