VPN IPsec: several LAN on one side - is it possible?

Hi people!

I have an IPsec Site to Site VPN branch (R2). There was a single LAN (LAN1) at HQ and another (LAN2) on the Executive.

The tunnel end points:

R1 - Microsoft ISA Server
R2 - Cisco 2921 SRI

LAN3 was created recently, behind R2 (see image below):

So, I need to access LAN3 of LAN1. How could I solve this problem? I see two options for now.

OPTION 1: Create a separate tunnel between R1 and R2

I see a problem here:

How to set a key for this tunnel?
If I run something like this:
ISAKMP crypto key LAN1_to_LAN2_key address 1.1.1.1
then LAN1, LAN2 tunnel will be abandoned due to the modified key
Everything else looks good - political maps, road maps, etc.
Traffic stand between them

OPTION 2: Create a summary route in config VPN

Questions:

R1 does not seem to support this kind of configuration (source, article "political quick mode negotiation fails with an error 'No configured policy'")

How could I solve this problem?

Running-config (security framework) is attached

On the side of Cisco, it's easy to solve. I can't explain how to fix the side R1 Microsoft but suspect that it is not difficult.

You don't want a second tunnel to solve this problem. You want to modify the access list that identifies the traffic is encrypted. If it were me, I would add this line to your existing access list

 permit ip 192.168.3.0 0.0.0.255 192.168.101.0 0.0.0.255

or alternatively, you can replace this line

 permit ip 192.168.2.0 0.0.0.255 192.168.101.0 0.0.0.255

with this line

 permit ip 192.168.2.0 0.0.1.255 192.168.101.0 0.0.0.255

VPN IPSec in LAN-2LAN tunnel configuration

Hi all!!

I'll put up a tunnel between a cisco 1841 router and a VPN 3000 Concentrator LAN LAN 2 ipsec.

Here is running for the router configuration and basically what I want to know is to ensure that I put everything in place to do this work. So can you please take a look and see if you find something a little odd and if so let me know!

Thank you very much in advance for your help

Glenn

Thanks for the configuration.

So you're natting and then to encrypt traffic natted. Which is totally fine. The reason, your ping does not work after the application of cryptography is due to the ACL entries below:

access-list 101 permit icmp any any echo

access-list 101 permit icmp any any echo response

The acl entries above are part of the traffic interesting Crypto. So once you apply the card encryption the router is supposed to encrypt all ICMP Echo and Echo-Reply, including traffic that is presented with the ip address of your 201.x.x.x. If you remove these two entries of the ACL 101 and apply only the below entries, then the ICMP should work with the applied crypto map.

access-list 101 permit ip 172.4.4.0 0.0.0.255 172.17.0.64 0.0.0.7

access-list 101 permit tcp host 172.4.4.5 host 172.17.0.65 eq 1000

access-list 101 permit udp host 172.4.4.5 host 172.17.0.65 eq 1000

After making the changes, make sure that crypto acl is images mirror on VPN3000 and router, or otherwise you will have problems in the implementation of the tunnel.

I would like to know how the test goes without the ACL 101 ICMP entries.

Kind regards

One to many with several tables on one side and a table on the side "several."
Sorry for the confusion in the title. Here's my question. In my program, I have 2 different tables that store the 2 different types of entities. Each entity has a list of attachments that I stored in a table of common attachments. There is a one-to-many relationship between the entity and the attachments table tables.

() ENTITY_ONE
ID
NAME
)

() ENTITY_TWO
ID
NAME
)

ATTACHMENTS)
ID
ENTITY_ID
ATTACHMENT_NAME
)

ENTITY_ID of attachments table is used to link the attachments to the one entity or two entity. All codes are generated by a single sequence. Thus, they are always unique. My question is how can I map this relationship in the EntityOne, EntityTwo and attachment JAVA class?
For EntityOne and EntityTwo, you can simply define a normal OneToMany mapping using the foreign key.
You use the TopLink API or APP? JPA requires a mappedBy to the OneToMany, so this may be more difficult. You should be able to simply add a JoinColumn on the OneToMany and make the Insertable/editable = false column.

To fix, you could either map the foreign key as a Basic (DirectToFieldMapping) and maintain in force in your model or use a VariableOneToOne to TopLink mapping (this will require a common interface on behalf of entities).

Cisco's VPN IPSec client for LAN connectivity

I've looked through further discussions and were not able to find a clear answer on this, so I apologize if this is a duplicate question.

I have the client setup Cisco VPN on an ASA 5505 with tunneling split. I can connect to the VPN very well. I can access the internet fine. I can't get the LAN, however. I try to do a ping, telnet, rdp, etc devices on the side LAN of the firewall without a bit of luck. I have torn down and configure the VPN several times via the CLI and I even used various configurations by using the wizard, all this without a bit of luck. Any help would be appreciated.

VPN IPSec S2S problems

Hello

I have a headquarters and a remote site and I want to get a VPN site-to site between the two. I have the following Setup on each router. 'Show encryption session' says that the VPN is in the IDLE-UP condition (and my somewhat limited understanding of virtual private networks, this means that the phase 1 of IKE is complete and waiting for phase 2) When you run a "debug crypto ipsec" on the remote site, I get "no ip crypto card is for addresses local 100.x.x.x" and the VPN remains to IDLE-UP. The ACL on the external interface allows the IP of the remote site. I have CBAC running on the external interface of both routers and ACL permits all traffic between the addresses 100.x.x.x and 200.x.x.x. Could someone help me with the config? I have to do something wrong somewhere.

Thank you!

Shaun

Hi Shaun,

Some comments...

The QM_IDLE means that the phase 1 is established. (sh cry isa his)

You should see with "sh cry ips its" that he has put SAs in place for IPsec encryption/decryption of traffic for the phase 2.

The ACL for VPN (the crypto ACL) should be one mirror of the other (you have "all" on one side and two statements by the other peer network.

You do NAT, therefore, there should be a 'workaround NAT rule' VPN traffic (to remove the IPsec NAT traffic).

This should be it.

Blocks VIRTUAL local network access to a tunnel VPN IPSec on WRV200?

I have two identical WRV200 wireless routers which are connected by a VPN IPSec tunnel. This goes to my LAN LAN of my parents. Everything works well.

But I also have my WRV200 configured for two VLANS. Vlan1 for my network and secure wireless access. VLAN2 for a WiFi not secure for customers.

My problem is that my guest on VLAN2 slips through the VPN devices and access on LAN of my parents. I'm looking for a way to block to do this.

I use the version of the software on the two routers (v1.0.39).

For what it's worth, I know that my receive an IP address in the range 192.168.x.101 DHCP - 199. I could assign a different range if that helps. I thought that I could block this beach on the remote router firewall, but I see there is blocking a single IP address at the time, maximum of 8. Am I missing something?

Or could I put something weird in the routing tables somewhere to get the IPs guest out of lala land?

Any suggestions are appreciated. I can't be the only one in this boat.

Steve

Try to check local and remote, vpn under safe group settings if you change the ip address range subnet. Don't include the range of ip addresses of the computers wireless comments so that it will not pass through the vpn tunnel. If there is no ip range option, you must to the subnet of the network in order to control the ip address you want to allow on the vpn tunnel.

VPN/IPSec-L2L - Question?

Hello!

Recently, I was doing some troubleshooting on a connection VPN/IPSec Lan-to-Lan between a Cisco PIX515E and a Linux firewall. My question concerns the configuration and is not the problem itself.

Traffic interesting (encrypted traffic) defined and configured the LAN of PIX (inside) and the distance public IP? Which means that the Peer IKE and the interesting remote control LAN/IP are the same... and it works!

Any ideas?

Thank you

JP

As long as you source the package from the local network of Pix to remote public IP, the tunnel will work well and works :-)

So, if you really look at the fluidity of the traffic, you're sourcing traffic from Pix LAN intended to public IP remote that corresponds to the defined access list. Thus, the pix knows he has encrypt traffic and now seeks the cryptographic endpoint points (pix outside IP public IP remotely) and sends the encrypted packets. So, this configuration works perfectly.

In fact, Pix will not allow Telnet the external of the pix interface unless the traffic is through an IPSEC Tunnel and it was one of the establishment who gave a telnet access to the external interface of the Pix, it's LAN to the public IP of Pix through an IPSEC Tunnel.

VPN site to Site with a side PAT

Hi all

I created a VPN site-to site between two ASA 5505 s, with one side having a static public IP address and one side behind a device with PAT. UDP 500 is sent to the ASA.

The tunnel works very well if the launched of the side behind the PAT, but may not be brought after on the other side.

Here's what I see in the system log during initialization of the 'wrong' side:

Is it still a problem with PAT?

Best regards

Tobias

Hello

To be honest, these are sometimes a little hard the problems especially when you do not have access to actual devices.

For me the newspapers you shared seem to indicate a problem with the negotiation of Phase 1 where this local line sends proposals of Phase 1 to the remote device until he returned their enough responsible for negotiating to complete.

So, I would try to confirm the device to remote site that this traffic is indeed allowed. For example, you can check the remote via a management connection VPN device when the VPN is NOT upward and see if there is no sign of VPN negotiating taking place when you start the other site traffic. That said if he still sees the initial messages in the direction that has problems with the opening of the tunnel.

When you launch the negotiation this site VPN, what you see with the release of

ISAKMP crypto to show his

or with the latest software

See ikev1 crypto his

Try to take out several times while you generate the traffic to the VPN

If the remote device does not respond at all you would see probably something like MM_WAIT_MSG2, which means that the local VPN device awaits the first response (second message to trading) of the remote VPN device.

Maybe this will help you narrow down the problem a bit.

Remote VPN - no remote LAN connectivity

Hi all

I'm having a problem with my remote access VPN to home. I have a router 800 series which is serves as the VPN (this is also my ADSL router modem), and there isn't enough work as it should...

I can establish a connection to the outside world, and when I run show crypto isakmp/ipsec his I see relevant entries. However, my problem is that once connected, I cannot ping anything in my local network. I can't ping even inside my ADSL router interface. I have another 800 series which is the next leap in broadcasting wireless clients, and is not accessible by ICMP either when it is connected through the VPN.

I won't go through all the troubleshooting steps that I've taken the case, this post will be a saga. I guess it's a routing problem or a NAT? It is not all NAT entries for the VPN client when it is connected, so I think that I bypassed that correctly.

I stripped my config back a bit just to try to make it work, I've pasted below:

Well, if you see encrypted/decrypted packets move away a lot of problems.

You can TEST inside the router of the VPN Client (LAN) IP?

This local network should have a default gateway pointing to the router or a route from the pool of VPN.

When you create a GRE tunnel between two routers, there should be a routing decision to reach the Remote LAN through local (rather than exit directly the physical interface) tunnel interface.

This could be accomplished by EIGRP, but you can check if the adjacency is built.

As a test, what happens if you add a static route saying (reach remote LAN, sending traffic to the tunnel interface).

Check if the GRE tunnel comes up with sh interface tunnel

Exit only on one side

My ipod classic only gives me an audio output on one side. I tried several headphones, it's the ipod that does not reach me. Can any ideas on how I fix?

Probably a problem of material with plug headphones. However, you can try to do a Reset (reboot) of iPod

Learn how to reset your iPod - Apple Support

If this does not help, you can try to do a restore, in case the problem is related to the software. This erases the iPod and assigns the default condition "factory". The restore button is on the recapitulation of the iPod settings screen in iTunes. If a restoration is not enough, it is likely to be a hardware problem.

If it's a defective headphone plug, you can get audio out to the dock, with an accessory connector. For example

iPhone 6, one side of load

my iphone 6 now load only on one side, I tried different usb cable and no luck. After doing several searches online, I replaced the loading port and apparently did not help. phone is out of warranty so the apple support will do nothing.

any thoughts of what could cause this?

I do not understand your question? What do you mean "only the load on one side? Pin male lightweight port is bidirectional, but female lightning port has pins on one side.

PIX of Pix VPN with no LAN

Same old story, but I have been able to resolve. We have recently resumed with 501 to 506 VPN client, but can not access the network from one side to the other resources. (Ping, browse, telnet...). The two attached configs. Thanks in advance.

You have BA/Decr on both sides, are you sure that the TWO parties can not access the other?

Cisco's VPN IPSec help please

Hi all

I have 3 sites, the main site has a cisco firewall mikrotik router.

There is a vpn ipsec existing between the cisco router and another router cisco on the site of the 2nd and it works well.

Now, I've added an another vpn between a 3rd site and main site. The router on the 3rd site is a mikrotik firewall.

I had the vpn on the main site and the 3rd site where the mikrotik firewall is and it worked well.

then for some reason, the vpn with the 3rd site has failed and I could not get it working again.

When looking for answers, I see that the vpn for the 3rd site States the following:

#pkts program: 46, #pkts encrypt: 46, #pkts digest: 46
#pkts decaps: 0, #pkts decrypt: 0, #pkts check: 0

It seems that no traffic is coming back to the cisco

I also found the following output below to diagnose the problem.

It seems that there is communication, but if I read this right, it looks like the cisco established a new number but the other end is not the new number

Comparing encrypt of 46 to 47436 counters, it seems that router is ecncrypting the traffic, but we do not get any interesting traffic on the remote side.

Most likely, you might want to check on the remote site, if you see counters increment in parallel decryption and encryption of the counters are incrementing or not.

On the router IOS, if are incrementing counters encrypt, and confirm that you have not any tunnel existing before the router can be seen same proxy IDs, which is already negotiated with other peer.

Finally, please make sure that the ESP, 50 protocol traffic is not blocked in transit.
I hope this helps.

Pool of dhcp NAT VPN to the LAN on router 2911

I need nat the ips assigned by dhcp vpn to my LAN pool. My problem is that I do not know which interface to set my nat statement on since there is no interface that is in the same subnet as my dhcp pool. Any help would be appreciated.

For remote client ipsec, you must have DVTI according to configuration described here:

http://www.Cisco.com/en/us/docs/iOS/12_3t/12_3t14/feature/guide/gtIPSctm...

'use ip nat inside' on the virtual model and 'ip nat outside' on the inside of the interface.
