2 crypto maps to the external interface? Possible?
Hi, I have a little problem with a PIX 515 UR on FOS 6.3 (1).
What I'm trying to do is to run 2 VPN site to site to him. The thing is: although I can get two separate crypt cards into the config, its only the more recent which is active when I do a ' sh crypto his '.
Anyone have any ideas?
TIA-
Gary
I do multiple like this:
I have the main Board, applied externally:
toXXXX interface card crypto outside
Then, I build maps more screaming like ACL if:
toXXXX 20 ipsec-isakmp crypto map
card crypto toXXXX 20 match address no_nat (name of the ACL)
card crypto toXXXX 20 peers set x.x.x.x
toXXXX 20 transform-set mytrans crypto card
life safety association set card crypto toXXXX 20 seconds 3600 4608000 kilobytes
toXXXX 40 ipsec-isakmp crypto map
card crypto toXXXX 40 correspondence address toACME (name of the ACL)
card crypto toXXXX 40 peers set x.x.x.x
toXXXX 40 transform-set mytrans crypto card
life safety association set card crypto toXXXX 40 seconds 3600 4608000 kilobytes

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

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.

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 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.
Post edited by: rcordeiro
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.

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.

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

IP 66.102.7.22 255.255.255.248The new IP address will be 66.102.7.18 255.255.255.248. Also, is this the right syntax?

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.

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.

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

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

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!
Concerning

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.

1: try to add the following command in your router.
Panel MultiLink virtual-model 1
2: set 'crypt map rtp' command in virtual model 1 void-configuation.
3: remove 'crypt map rtp' command of all the interface configuration and closure of the serial interface.
4: highly recommended to remove the following command from each serial interface.
Check IP unicast reverse path
5: If still does not work, apply new 'crypt card rtp"command in all interfaces of Seraglio under configuration.
