VPN IPSEC ASA with overlap proxy-ID

All,

Currently I have a VPN from a single network ASA spoke to a single hub of AAS, so I set up my access lists so that the source is specific to speak it (for example 192.168.1.0/24) and I use the word "any" key for destination. I need to add a few more VPN connections, so can I just add lower inside specific networks to any instruction in the card encryption. See below.

outside_10_cryptomap list extended access allowed object-group home-networks-networks another ip

outside_20_cryptomap list of allowed ip extended access object-group network inside everything

card crypto outside_map 10 correspondence address outside_10_cryptomap

card crypto outside_map 10 set peer 1.1.1.1

outside_map card crypto 10 the transform-set ESP-3DES-MD5 value

card crypto outside_map 20 match address outside_20_cryptomap

card crypto outside_map 20 peers set 2.2.2.2

outside_map card crypto 20 the transform-set ESP-3DES-MD5 value

Gregory

Now I come to think of it, I remember a problem with less specific entries in the ACL before more specific entries.

So it should work, but you must make sure that the most specific comes before the less specific that you seem to have done with your config.

VPN IPSec ASA with two ISP active

Hi ALL!

I have a question.

So I have ASA with 9.2 (1) SW connected to ISP with active SLA.

I need to configure redundant IPSec VPN via ISP2, while all other traffic must go through isps1. In case if one of the ISP goes down all including VPN traffic must be routed via ISP alive.

I have configured SLA and it works.

ciscoasa # display route performance
Route 0.0.0.0 isps1 0.0.0.0 10.175.2.5 5 track 1
Route isp2 0.0.0.0 0.0.0.0 10.175.3.5 10 track 2
Route isp2 172.22.10.5 255.255.255.255 10.175.3.5 1 excerpt 2

Here we can see if isps1 and ISP2 are RISING, all traffic passes through isps1, but traffic intended for the remote peer IPSec 172.22.10.5 passes by ISP2.

This configuration works just at the moment when isps1 or isp2 is down or if a static route for 172.22.10.5 deleted. Where two Internet service providers are increasing to ASA does not send the next remote IPSec datagrams.

Thank you in advance,

Hi anton,.

If you check the log message on your ASA R301-IS , he's trying to build the tunnel VPN with both IP and it receives packets of asymmetrically your distance ciscoasa.

TO avoid this asymmetrical connection, point your IP from peers as primary & secondary on your R301-EAST

set peer 10.175.3.10 10.175.2.10

Delete the track on your routing entries

Route isp2 172.22.10.5 255.255.255.255 10.175.3.5

This should work for you.

Similalry lower your ISP 2, you should see VPN tunnel is mounted with isps1 one.

VPN IPSEC ASA with counterpart with dynamic IP and certificates

Hello!

Someone please give me config the work of the ASA for ASA Site to Site IPSEC VPN with counterpart with dynamic IP and authentication certificates.

He works with PSK authentication. But the connection landed at DefaultRAGroup instead of DefaultL2LGroup with certificate

authentication.

Should what special config I ask a DefaultRAGroup to activate the connection?

Thank you!
```
The ASA uses parts of the client cert DN to perform a tunnel-group  lookup to place the user in a group.  When "peer-id-validate req" is  defined the ASA also tries to compare the IKE ID (cert DN) with the  actual cert DN (also received in IKE negotiation), if the comparison  fails the connection fails. know you could set "peer-id-validate cert"  for the time being and the ASA will try to compare the values but allow  the connection if it cannot. 
```
In general I would suggest using option "cert."

With nocheck, we are simply not strict on IKE ID matchin the certificate, which is normally not a problem of security :-)

L2l VPN between ASA with the IP address public and CISCO2911 behind the ISP router with port forwarding

Hi all

My apologies if this is a trivial question, but I spent considerable time trying to search and had no luck.

I encountered a problem trying to set up a temporary L2L VPN from a Subscriber with CISCO2911 sitting behind the router of the ISP of an ASA. ISP has informed that I can't ignore their device and complete the circuit Internet on the Cisco for a reason, so I'm stuck with it. The Setup is:

company 10.1.17.1 - y.y.y.y - router Internet - z.z.z.z - ISP - LAN - 10.x.x.2 - XXX1 - ASA - 10.1.17.2 - CISCO2911 - 10.1.15.1 LAN

where 10.x.x.x is a corporate LAN Beach private network, y.y.y.y is a public ip address assigned to the external interface of the ASA and the z.z.z.z is the public IP address of the ISP router.

I have forwarded ports 500, 4500 and ESP on the ISP router for 10.1.17.2. The 2911 config attached below, what I can't understand is what peer IP address to configure on the SAA, because if I use z.z.z.z it will be a cause of incompatibility of identity 2911 identifies himself as 10.1.17.2...

So I suggest:

IPSec VPN between ASAs with same subnet for disaster recovery

Hello

I need some clarification from you guys.

To do disaster EasyVPN tunnels for the Cisco ASA 5505 firewall recovery site. Now, there is only one main site and 3 remote sites.

Dr., must use the same subnet that it is on the main site because virtual machines Vmware will be replicated to DR.

For the DR we use Double-Take software.

What is the best solution for this? I think we could use NAT of Destination on ASAs. Other sites (HQ and remote control) will be directed to only address NAT of the

DR and not real which is the same as on the main site.

So guys, will this work? We are using IPSec VPN? In packet - trace on ASA, I see that the package is the first using a NAT, and then encrypted, so it should work, Yes?

I hope someone can confirm this.

I can confirm that this will work certainly,

for prior type natting see 8.3:

http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a0080b37d0b.shtml#diag

for 8.3 and later it is also achievable.

LT2P configuration vpn cisco asa with the internet machine windows/mac issue

Dear all,

I have properly configured configuration vpn L2TP on asa 5510 with 8.0 (4) version of IOS.

My internet does not work when I connect using the vpn. Even if I give power of attorney or dns or I remove the proxy

It does not work. only the resources behind the firewall, I can access. I use the extended access list

I tried also with the standard access list.

Please please suggest what error might be.

Thank you

JV

Split for L2TP over IPSec tunnel tunnel is not configured on the head end (ASA), it must be configured on the client itself, in accordance with the following Microsoft article:

PIX with VPN to Checkpoint with overlapping subnets

I have a client with a PIX runs code 6.3.

They need establish an IPSec Tunnel for one of its customers with a Checkpoint firewall.

Both organizations use 10.1.0.0/16 and I'd like to nat to 10.180.0.0 Home Office 16 and the remote client to 10.181.0.0.

The document on the site Web of Cisco PIX and VPN concentrators is less useful. I don't think the text describing the image is correct.

Help with ACL and static NAT is greatly appreciated.

Frederik

Apologies, should have asked. Which office has the pix and the control point. I write this as if the two ends were firewall pix so that's fine and we can see if that helps.

VPN L2L ASA with NAT

Hello, I was hoping someone might have an example of a site to site VPN configuration where the ASA is statically NATting its internal network. Basically the same configuration like this, but instead of "not nat", the ASA is NATting. So instead of the remote site, connect to the local network 10.10.10.0/24, ASA would be NAT at 172.16.17.0/24 for example.

http://www.Cisco.com/en/us/products/ps9422/products_configuration_example09186a0080b4ae61.shtml

Thank you.

Mike

It's not very complicated, just keep in mind that NAT is done before the encryption.

So if you your network 10.10.10.0/24 nat internal to 172.16.17.0/24:

public static 172.16.17.0 (Interior, exterior) 10.10.10.0 netmask 255.255.255.0

You can use the address translated into your crypto-ACL:

REMOTE VPN ip 172.16.17.0 access list allow REMOTE-NET 255.255.255.0 255.255.255.0

I suppose that you run ASA v8.3 + that you referred to an older document. If you have a more recent software, the logic is the same but the NAT commands differ.

How to configure bandwidth allowed on the VPN IPSec ASA tunnels?

ASA 5505 8.2.1

ASA 5520 8.4

We currently have a tunnel set up between 2 ASAs

is 1 - possible to assign 1.5 Mbps of Bandwidth (BW) to this tunnel? Then if Tunnel number 2 is set up I could assign 2 Mbit to this one for example?

I'm not talking to prioritize certain type of traffic on the IPsec tunnel, I'm talking about Tunnel 1 to 1.5 Mbps of BW guaranteed for all traffic that passes through it. Same for tunnel 2

Then

VPN to ASA with ISE and Posture

Hello

I'll put up a new facility of ISE. I want to install AnyConnect 4.1 and use ISE for authentication & posture validation. I'm ok with the side of the authentication of things.

This configuration applies to time AnyConnect 3.1 & 4.x?

Any help would be appreciated.

Thank you

Hi Stuart,

Yes - this configuration applies as well to the AC3 and AC4.

The new feature of AC4 is available directly from ISE ability:

IOS - help with VPN IPsec L2L with NAT

Hello guys

I tried to get VPN to work for a specific scenario where I do NAT for VPN traffic to avoid the duplication of subnet.

I found several guides on cisco.com, but all the ones I found does not (or how) overload NAT (for internet traffic), I need for my setup.

http://www.Cisco.com/en/us/Tech/tk583/TK372/technologies_configuration_example09186a00800b07ed.shtml

http://www.Cisco.com/en/us/products/ps5855/products_configuration_example09186a0080a0ece4.shtml

Basically, I need to know how the configuration looks like when make you static NAT in a VPN tunnel as well as provide internet connectivity using NAT in the same router?

I have attached a drawing that needs to better explain my needs.

Someone knows a guide that shows how to do this?

Best regards

Jesper

You can use a static policy NAT NAT the traffic:

access-list 101 permit ip 10.0.0.0 0.0.0.255 10.30.10.0 0.0.0.0.255

access-list 102 deny ip 10.0.0.0 0.0.0.255 10.30.10.0 0.0.0.0.255

access-list 102 permit ip 10.0.0.0 0.0.0.255 any

policy-NAT allowed 10 route map

corresponds to the IP 101

internet-NAT allowed 10 route map

corresponds to the IP 102

IP nat inside source static network 10.0.0.0 road policy-NAT 10.30.10.0/24-feuille

IP nat inside source map route internet-NAT interface overloading

Hope that helps.

LAN-to-LAN IPsec VPN with overlapping networks problem

I am trying to connect to two networks operlapping via IPsec. I already have google and read

http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a0080b37d0b.shtml

Details:

Site_A use ASA 5510 with software version 8.0 (4) 32. Site_A use 10.100.0.0/24, 10.100.1.0/24 and 10.100.2.0/24 inside networks. 10.100.0.0/24 is directly connected to ASA (like vlan10), 10.100.1.0/24 and 10.100.2.0/24 are routed.

Site_B use Linux box and networks 10.100.1.0/24, 10.100.2.0/24, 10.100.3.0/24 and so on (mainly 10.100.x.0/24). I have not implemented this ASA, we took over this infrastructure without other documentation whatsoever.

According to the above link I should use double NAT. Site_B will see the Site_A as 10.26.0.0/22 networks, and Site_A see networks in Site_B as 10.25.0.0/24. Site_A is allowed access only 10.100.1.0/24 in the Site_B, and Site_B is allowed access to all the networks of the Site_A 10.100.x.0/24 - so / 22 10.26.0.0/22 mask. I would like, for example, ssh to host in the Site_B to host the Site_A using 10.26.1.222 as the destination ip address (and it should be translated in 10.100.1.222 on the side Site_A). I'm looking for something like ip nat type match-host in Cisco routers - I want to translate only a part of the network address leave the intact host Party. Anyway, following the steps from the link displayed above everything is ok until the command:

static (companyname, outside) 10.26.0.0 access list fake_nat_outbound

which translates into:

WARNING: address real conflict with existing static

Those are redirects to port on Site_A used for mail, webmail, etc. What should I do to keep the redirects from the Internet to companyname vlan and at the same time to have work l2l ipsec tunnel linking networks that overlap?

Thank you in advance for any help or advice.

Are you sure that static-config does not make to the running configuration?

By applying this 'static big' you're essentially trying to redirect the ports, which have already been transmitted by the rules in your existing configuration. This explains the caveat: what you are trying to do has some overlap with existing static.

(Sorry for the use of the transmission of the word, but this behavior makes more sense if you look at it like this; although "port forwarding" is not Cisco-terminology.)

But... whenever I stumbled upon this question, the warning was exactly that: a WARNING, not an ERROR. And everything works as I want it to work: the specific static in my current config simply have priority over static grand.

If you would like to try to do the other opposite you would get an error (first static major, then try to apply more specific) and the config is not applied.

So could you tell me the config is really not accepted?

Thank you

If the RIP is not absolutely necessary for you, try adding the default route to R2:

IP route 0.0.0.0 0.0.0.0 172.16.2.1

If you want to use RIP much, add permissions ACL 102:

How to establish a tunnel vpn ipsec using DNS with ASA 5505?

Hello

I m get a dynamic IP address public and what I m trying to do is establish a tunnnel remote vpn using IPSec, which I realize my provider but each time resets of sessions or ASA 5505 reset, I get a new public IP and I need to put the new IP address on the remote client, so I can establish the vpn...

How can I establish a vpn ipsec using DNS? For this scenario, the remote client vpn is a vpn phone, but it could be any vpn client.

Private private Public IP IP IP

PBX - Telephone (LAN) - ASA 5505-(Internet)-(router) Remote Site-(LAN) VPN-

Kind regards!

Ah ok I see, Yes in this case there is no that you can do other than request a static IP address from your ISP.

Kind regards.

PS: Don't forget to mark this question as answered. Thank you!

Setup for use with Cisco Anyconnect VPN IPsec

So, I had trouble setting up VPN on our ASA 5510. I would use IPsec VPN so that we don't have to worry about licensing issues, but what I have read you can do with and always use Cisco Anyconnect. My knowledge on how to set up VPN especially in iOS version 8.4 is limited, so I've been using a combination of command line and ASDM.

I am finally able to connect from a remote location, but once I log in, nothing else works. What I've read, you can use IPsec for client-to-lan connections. I use a pre-shared for this. Documentation is limited on what should happen after have connected you? Shouldn't be able to local access on the vpn connection computers? I'm trying to implement work. If I have VPN from home, should not be able to access all of the resources at work? According to me, because I used the command-line as ASDM I confused some of the configuration. In addition, I think that some of the default policies are confused me too. So I probably need a lot of help. Here is my current setup with the changed IP address and other things that are not related to deleted VPN.

NOTE: We are still testing this ASA and is not in production.

Any help you can give me is greatly appreciated.

Statistical accounting of user

I would recommend buy AnyConnect Essentials. The cost of the license is nominal - list of US $150 for the 5510. (piece number L-ASA-AC-E-5510 =)

Meawwhile you can use the Cisco VPN client inherited with IKEv1 IPSec remote access VPN using profiles *.pcf.

I believe you can also use the client Anyconnect client SSL or DTLS transport access remotely (non-IPsec) without having to buy the license Anyconnect Essentials for your ASA focus.

As an aside, note that if you want to use AnyConnect Mobile (e.g. for iPhone, iPad, Android, Blackberry etc.clients) you will also get the additional license for it (L-ASA-AC-M-5510 =, also price US $150)
