Attack detected in Journal of the VPN VPN?

Hello

I see the King of the messages in the VPN log:

4 Mar 15:55:10 2010 VPN Log [Tunnel negotiation Info] > main initiator Mode to send 1 package

These messages have flooded the page of the newspaper and have the same hour: minute: second

Is this some kind of attack or back?

I have a Linksys RV082, firmware 2.0.0.19 - tm

Thank you very much

Oliver

Possible. Is the RV082 on the other side off as well?

Assuming that you have an active IPSEC security association (i.e. "show crypto ipsec his" shows the tunnel is up), please perform a packet trace to see why it's a failure:
```
 packet-tracer input inside tcp 192.168.116.1 1025 192.168.1.1 80 detail
```

The VPN Clients cannot Ping hosts

I'll include a post my config. I have clients that connect through the VPN tunnel on the 180.0.0.0/24 network, 192.168.1.0/24 is the main network for the office.

I can connect to the VPN, and I received a correct address assignment. I belive tunneling can be configured correctly in the aspect that I can always connect to the internet then on the VPN, but I can't ping all hosts on the 192.168.1.0 network. In the journal of the ASDM debugging, I see pings to the ASA, but no response is received on the client.

Any help would be greatly appreciated, I'm currently presuring my CCNP so I would get a deeper understanding of how to resolve these issues.

Hello

-be sure that the destination host 192.168.1.x has a route towards 180.0.0.0 by the ASA gateway.

-Configure the following figure:

capture capin interface inside match icmp 192.168.1.x host 180.0.0.x

capture ASP asp type - drop all

then make a continuous ping and get 'show capin cap' and 'asp cap.

-then check the ping, the 'encrypted' counter is increasing in the VPN client statistics

I would like to know about it, hope this helps

Check the ISE for the VPN Cisco posture

Hello community,

first of all thank you for taking the time to read my post. I have a deployment in which requires the characteristic posture of controls for machines of VPN Cisco ISE. I know that logically once a machine on the LAN, Cisco ISE can detect and apply controls posture on clients with the Anyconnect agent but what about VPN machines? The VPN will end via a VPN concentrator, which then connects to an ASA5555X that is deployed as an IPS only. Are there clues to this?

Thank you!

The Cisco ASA Version 9.2.1 supports the change in RADIUS authorization (CoA) (RFC 5176). This allows for the gesticulations of users against the ISE Cisco VPN without the need of an IPN. Once a VPN user connects, the ASA redirects web traffic to the LSE, where the user is configured with a Network Admission Control (NAC) or Web Agent. The agent performs specific controls on the user's computer to determine its conformity against one together configured posture rules, such as the rules of operating system (OS) patches, AntiVirus, registry, Application, or Service.

The posture validation results are then sent to the ISE. If the machine is considered the complaint, then the ISE can send a RADIUS CoA to the ASA with the new set of authorization policies. After validation of the successful posture and CoA, the user is allowed to access internal resources.

Routing problem between the VPN Client and the router's Ethernet device

Hello

I have a Cisco 1721 in a test environment.

A net 172.16.0.0/19 simulates the Internet and a net 192.168.1.0/24 simulates the net, the VPN tunnel must go to (intranet).

The net 172.16.0.0 depends on the router 0 FastEthernet, Intranet (VPN) hangs on Ethernet 0.

The configuration was inspired form the sample Configuration

"Configuring the Client VPN Cisco 3.x for Windows to IOS using Local extended authentication"

and the output of the ConfigMaker configuration.

Authentication and logon works. Client receives an IP address from the pool. But there's a routing problem

side of routers. Ping client-side - do not work (the VPN client statistics that count encrypt them packets, but not to decrypt).

Ping the router works too, but decrypt and encrypt customer statistics in VPN packets count progressive

(customer has a correct route and return ICMP packets to the router).

The question now is:

How to route packets between the Tunnel and an Ethernet device (Ethernet 0)?

conf of the router is attached - hope that's not too...

Thanks & cordially

Thomas Schmidt

Thomas,

Can't wait to show something that might be there, but I don't see here. You do not have the card encryption applied to one of the interfaces, perhaps it was not copied. Assuming your description you do it, or should it be, applied to the fa0 and you are connected. Try how you ping? Since the router or a device located on E0? If you ping the router, you will need to do an extended ping of E0 to the ip address of the client has been assigned. If your just ping the router without the extension, you will get sales and decrypts that you declare on the client. Have you tried to ping from the client to interface E0? Your default route on the router is pointing to fa0? You have a next hop to affect? You have several NIC on the client pc? Turn off your other network cards to check that you don't have a problem with routing on the client if you have more than one.

The VPN client VPN connection behind other PIX PIX

I have the following problem:

I wanted to establish the VPN connection the client VPN to PIX on GPRS / 3G, but I didn t have a bit of luck with PIX IOS version 6.2 (2).

So I upgraded PIX to 6.3 (4) to use NAT - T and VPN client to version 4.0.5

I have configured PIX with NAT-T(isakmp nat-traversal 20), but I still had a chance, he would not go through the 1st phase. As soon as I took nat-traversal isakmp off he started working, and we can connect to our servers.

Now, I want to connect to the VPN client behind PIX to our customer PIX network. VPN connection implements without problem, but we can not access the servers. If I configure NAT - T on the two PIX, or only on the customer PIX or only on our PIX, no VPN connection at all.

If I have to connect VPN client behind PIX to the customer's network and you try to PING DNS server for example, on our PIX, I have following error:

305006: failed to create of portmap for domestic 50 CBC protocol translation: dst outside:194.x.x.x 10.10.1.x

194.x.x.x is our customer s address IP PIX

I understand that somewhere access list is missing, but I can not understand.

Of course, I can configure VPN site to site, but we have few customers and take us over their servers, so it'd just connect behind PIX VPN and client connection s server, instead of the first dial-in and then establish a VPN connection.

Can you please help me?

Thank you in advan

The following is extracted from ASK THE DISCUSSION FORUM of EXPERTS with Glenn Fullage of Cisco.

I've cut and pasted here for you to read, I think that the problem mentioned below:

Question:

Hi Glenn,.

Following is possible?

I have the vpn client on my PC, my LAN is protected by a pix. I can launch the vpn client to connect to remote pix. Authenticates the vpn client and the remote pix makes my PC with the assigned ip appropriate to its pool of ip address.

The problem that I am facing is that I can not anything across the pix remote ping from my PC which is behind my pix. Can you please guide me what I have to do to make this work, if it is possible?

My PC has a static ip address assigned with the default gateway appropriate pointing to my s pix inside interface.

Thank you very much for any help provided in advance.

Response from Glenn:

First of all, make sure that the VPN connection works correctly when the remote PC is NOT behind a PIX. If that works fine, but then breaks when put behind a PIX, it is probably that the PIX is PAT, which usually breaks IPSec. Add the following command on your PIX VPN client is behind:

fixup protocol esp-ike

See http://www.cisco.com/univercd/cc/td/doc/product/iaabu/pix/pix_sw/v_63/cmdref/df.htm#wp1067379 for more details.

If it still has issues, you can turn on NAT - T on the remote PIX that ends the VPN, the client and the remote PIX must encapsulate then all IPSec in UDP packets that your PIX will be able to PA correctly. Add the following command on the remote PIX:

ISAKMP nat-traversal

See http://www.cisco.com/univercd/cc/td/doc/product/iaabu/pix/pix_sw/v_63/cmdref/gl.htm#wp1027312 for more details.

NAT - T is a standard for the encapsulation of the UDP packets inot IETF IPSec packets.

ESP IPSec (Protocol that use your encrypted data packets) is an IP Protocol, it is located just above IP, rather than being a TCP or UDP protocol. For this reason, it has no TCP/UDP port number.

A lot of features that make the translation of address of Port (PAT) rely on a single to PAT TCP/UDP source port number ' ing. Because all traffic is PAT would be at the same source address, must be certain uniqueness to each of its sessions, and most devices use the port number TCP/UDP source for this. Because IPSec doesn't have one, many features PAT fail to PAT it properly or at all, and the data transfer fails.

NAT - T is enabled on both devices of the range, they will determine during the construction of the tunnel there is a PAT/NAT device between them, and if they detect that there is, they automatically encapsulate every IPSec packets in UDP packets with a port number of 4500. Because there is now a port number, PAT devices are able to PAT it correctly and the traffic goes normally.

Hope that helps.

Win 7 VPN client cannot access remote resources beyond the VPN server

I have a Win 7 laptop with work and customer Win 7 VPN set up, and through it that I can access everything allowed resources on the remote network.

I built a new computer, set up the Win 7 client with the exact same parameters everywhere, connected to the VPN with success, but can not access any of the resources on the remote network that I can on my laptop.

Win 7 64 bit SP 1

I did research online and suggestions have already had reason of my new set up. In addition, I have a second computer that I've set up the VPN client, and I'm having the same problem. VPN connects successfully, but is unable to access the resources.

Tested with firewall off the coast.

Troubleshooting Diagnostic reports: your computer seems to be configured correctly, distance resources detected, but not answered do not.

I created another VPN client on the new computer to another remote network and everything works perfectly.

Remember the old VPN connection to the remote network that does not work on the new computer works perfectly on Win 7 64 bit laptop computer.

So, what do I find also different between identical configurations "should be" where we work and two new machines is not?

It must be something stupid.

I know that they just delete the username and enter their own, but is there a way the client can be configured to where the username field will be always empty for all those who want access to the network via VPN? We have an ASA 5510 with version 7.0 (8) and a windows 2003 with IAS server for windows authentication. Thank you!

Hello

In FCP, you can configure a single line is not editable by the user (or the vpn client).

Simply insert an attack! Like this

! Username =

! SaveUserPassword = 0

! UserPassword =

! enc_UserPassword =

Subsequently the vpn client will not save registrations for these settings more.

IPSec VPN: connected to the VPN but cannot access resources

Hello

I configured a VPN IPSec on two ISP with IP SLA configured, there is a redundancy on the VPN so that if address main is it connect to the VPN backup.

QUESTIONS

-Connect to the primary address and I can access resources

-backup address to connect but can not access resources for example servers

I want a way to connect to backup and access on my servers resources. Please help look in the config below

When you say that "the external interface is downwards using failover techniques" you mean this failover occurred because the ASA is no longer able to reach the 31.13.72.1? Not that the actual interface is broken?

If this is the case, then the NATing is your problem. Since you're using the same VPN pool for VPN connections the ASA cannot distinguish between the two streams of traffic if the external interface is still in place. The SLA tracking only removes a route in the routing table, but does not affect what happens in the NAT process.

try to change the NAT statement follows him and the test (don't forget to remove the other statements to exempt of NAT for this traffic during the test):

NAT (inside,any) static static source NETWORK_OBJ_192.168.30.0_25 destination DM_INLINE_NETWORK_1 DM_INLINE_NETWORK_1 NETWORK_OBJ_192.168.30.0_25

If this does not work, I would either turn off the external interface when a failover occurs, or create a second connection profile that contains a separate mass of IP for the VPN connection and ask users to connect using this profile when a failover takes place. Don't forget to create Nat exempt instructions for this traffic also.

No traffic through the VPN tunnel but at the same time

Hey everybody,

Good enough at the end of my VPN configuration but I have a question. The VPN connection is established and the remote computer can set up a VPN with my router (phases 1 and 2 are ok) but I can't ping all devices on both sides. I think it might be something about the acl. I created an acl that I linked with my group of vpn, what should I do something with the card?

Here is the configuration of the router

Thanks for your help!

Sylvain,

Let me explain again:

IP nat inside source list 10 interface Dialer1 overload

overload of IP nat inside source list 110 interface Dialer1

Here you are from two ACL, but they are the same with the difference, that NAT 10 110 also but WITHOUT user VPN and everything inside. Problem is that 10 matches first, if the connection will not work. You can disable entry NAT with 10 110 because that will also:

no nat ip inside the source list 10 interface Dialer1 overload

That should be enough.

First of all, there is overlap crypto ACL with the VPN static L2L:

crypto ASA1MAP 10 card matches the address 101

access-list 101 extended allow ip 10.10.10.0 255.255.255.0 172.18.0.32 255.255.255.240
access-list 101 extended allow ip 172.18.0.32 255.255.255.240 10.10.10.0 255.255.255.0

I would remove the 2 lines of ACL 101 above because it is incorrect.

Secondly, from the output of ' cry ipsec to show his ", you seem to be getting the ip address of the"jdv1.australis.net.au", not"CorpVPN"pool pool. Therefore, the No. NAT ACL on the management interface is incorrect. I would just add a greater variety of education no. NAT so that it covers all your ip pool:

access-list no.-NAT-DU-MGMT scope ip 10.10.10.0 allow 255.255.255.0 172.18.0.0 255.255.255.0

Thirdly, even with your dynamic ACL 'OUTSIDE_cryptomap_65535.65535' crypto map, it only covers the 172.18.0.32/28, so I just want to add a wider range since it seems you get the ip address of the different pool:

OUTSIDE_cryptomap_65535.65535 list of allowed ip extended access all 172.18.0.0 255.255.255.0

Then I would disable the following group of access for purposes of test first:

no access-group MANAGEMENT - OUT Interface MANAGEMENT

Finally, please clear all the SA on your ASA and xlate, then reconnect to your vpn client and test it again:

delete the ipsec cry his

clear the isa cry his

clear xlate

Please let us know how it goes after the changes. If it still doesn't work, please please send again the last configuration and also to send the output of the following:

See the isa scream his

See the ipsec scream his

and a screenshot of the page of statistics on your vpn client. Thank you.

Hello

I would suggest you start by changing the pool VPN to something else than the current LAN network and see if that helps

These should be the configuration required to achieve this goal
- First remove us pool setup VPN VPN
- Then we delete the VPN Pool and create again with an another address space
- When then attach this new Pool of VPN again to the VPN configuration
- In the last step, we add a NAT0 / exempt for this new pool VPN NAT configuration and remove the old ACL line for the former group of VPN

How to configure the vpn using two segments in a tunnel?

Hi guys,.

Please help me how to set up two segment in a vpn tunnel. Our client has two segments which is 10.15 and 192.168. We have already established VPN connectivity. We can ping the 10.15 segment, but we can not ping 192.168. Attached is the sample configuration.

Hello

Your side has 192.168.202.0/24 and you are trying to PING 10.15 successfully but not 192.168.30.174

Check that the ASA has a route to 192.168.30.174 pointing to the external interface.

Also check that the customer has defined the 192.168.30.174 as part of the VPN traffic correctly.
