Split on PIX 7.2 tunnel (2)

I upgraded pix from the customer to 7.2 (2). Now, the split tunnel doesn't seem to work. The vpn works, but according to the vpnclient (4.8 and 5.0) still routing all data through the vpn connection.

All advice appreciated. Thank you!

The current configuration is attached.

L2TP Windows 7, split and site-to-site tunnel

Hi all

I'm going to this interesting problem that drives me crazy all day. I have ASA 5505 (ver 9) where I set up VPN site-to-site to another router and it works. Then I configured L2TP IPsec VPN on SAA with split tunneling, and I can reach my local network. The problem is when I am trying to reach this remote network that is behind this site-to-site VPN. Whatever I do, I'm not able to reach the network. This exact same setup works on different ASA with AnyConnect VPN.

So that's what I did:

(1) adds VPN subnet as ITS 2nd to the existing site-to-site VPN

(2) exemption from NAT configured for subnet VPN when you go to the remote subnet

(3) published the remote subnet to VPN client.

This should do the trick as it does when AnyConnect is in question.

I'll paste some commands concerning:

Someone at - he managed to get this configuration works? I guess I'm missing some details here, but I don't see that. Perhaps it does not work with L2TP?

Hello, Damir Reic.

What do you use NAT for L2TP-VPN? Split tunneling is help your users internet direcrly so you don't need to use NAT. It can be a source of problem as NAT works before VPN site to site. If your remote users traffic could be changed to NAT and IP traffic that wi source address will be different. And for this reason, it is not rules hiting your site-to-site VPN.

Split tunnel with ASA 5510 and PIX506.

Hello

I have the production between Asa 5510 (main office) and Pix 506 VPN tunnel. It is configured so that all traffic is encrypted and moves through the tunnel. This includes remote users behind Pix Internet traffic. I would like to use split tunnel and direct Internet traffic hitting the web directly from Pix instead of going through the tunnel. How can I do this safely? Please see current config Pix below:

I would do something by changing the acl that applies to your crypto card. You want to know what you want to support above the tunnel and then deny other networks.

If you have:

192.168.3.0/24

192.168.4.0/24

10.10.10.0/24

172.16.0.0/16

Do something like:

VPN access list allow 192.x.x.x ip 255.255.255.0 192.168.3.0 255.255.255.0

VPN access list allow 192.x.x.x ip 255.255.255.0 192.168.4.0 255.255.255.0

VPN access list allow 192.x.x.x ip 255.255.255.0 10.10.10.0 255.255.255.0

VPN access list allow 192.x.x.x 255.255.255.0 ip 172.16.0.0 255.255.0.0

Then when the traffic is destined for something other than these networks, it will go not to the ISP instead of the tunnel.

Split tunnel

Hi guys,.

I wonder if remote access VPN with split tunnel is using the home user or the corporate to surf internet connection own internet connection?

Any help will be greatly appreciated.

Thank you

Lake

Dear Lakeram,

Split tunneling allows you to access certain resources through the tunnel and all other traffic will be sent to your local proxy.

VPN traffic is defined by the VPN endpoint, for example:

192.168.1.0/24---Internet---ADSL ASA VPN client-

You can have the ASA push the network 192.168.1.0/24 to the customer. Once connected if the client tries to access everything that comes out of the scope of the network, this traffic will be sent to the LAN...

Here's an example with ASA and router.

ASA/PIX: Allow the tunneling split for the VPN Clients on the example of Configuration of ASA

http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a0080702999.shtml

ASA 8.x: allow the tunneling split for AnyConnect VPN Client on the example of Configuration of ASA

http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a0080975e83.shtml

Router allows the VPN Clients to connect to IPsec and Internet using Split Tunneling Configuration example

http://www.Cisco.com/en/us/products/HW/routers/ps274/products_configuration_example09186a0080819289.shtml

I hope it helps.

Thank you.

How to change AnyConnect VPN remote to complete the split tunnel tunnel?

I couldn't find an answer through the config of the SAA in the Cisco documentation and using Google. To activate the complete tunnel for the AnyConnect client group policy, I just need to change the policy of Tunneling split to all networks of tunnels and set list of network voice against zero, if I want someone who connects with the AnyConnect customer to guarantee mobility to use internet corp pipe?

Who, more you will also need a NAT nat rule VPN pool meets the ASA outside interface (or if address / hen you normally use for dynamic NAT).

There are a few good examples with illustrations in this document.

3 xVPN Client to PIX to the Internet

remote access VPN between the client and the PIXv6.2 works very well. We attach to the external interface of the PIX, and it allows us to access the resources inside. What should I do to get remote vpn clients access to the DMZ? What is a translation for the pool of vpn to the DMZ? Without using tunneling split down to the customer, can they access the Internet on the PIX they just in their tunnel? Is a proxy needs to be configured? Thank you all.

You'll currently have something like:

sheep allowed ip access-list

NAT (inside) 0 access-list sheep

To gain access to hosts on the DMZ interface, add the following:

nonatdmz ip access list allow

NAT (dmz) 0-list of access nonatdmz

Also, without split tunneling VPN clients cannot enter the PIX on the tunnel and then go back on the same interface to the Internet. The PIX won't send a return the same interface package, he entered the, which includes encrypted and unencrypted traffic. Sorry, no way around it.

SonicWall VPN PIX - does not, could someone help?

Hi all

I'm trying to set up an a 506th PIX VPN tunnel (firmware 6.3 (2)), a firewall SonicWall Pro. It does not at the moment. Phase 1 is ok but the phase 2 is not, the VPN tunnel has not been established, and the security association is removed after a minute or two. I enclose below the PIX config and an attempt to create VPN tunnel debugging output (slightly modified and cut for reasons of confidentiality). The PIX already has other two VPN configured which work perfectly.

I would be very grateful to anyone who could help me answer the following questions about this VPN configuration:

1. to debug output, which means the next?

ISAKMP (0): retransmission of the phase 2 (0/0)... mess_id 0xafc08a94

crypto_isakmp_process_block:src:remotevpnpeer, dest:vpnpix1 - dpt:500 e0 spt:500

ISAKMP: error msg not encrypted

2. in the config, I don't know if the 3 static controls are necessary and how it might interact... What do you think?

3. in what order things happen in the PIX when traffic is from the local network to remote network by VPN? What is NAT then treatment then setting up VPN to access list? or or treatment, then NAT and VPN to access list? or another possibility?

4. How can I get it work?

Thank you very much in advance for any help provided,

A.G.

This indicates the PIX not NAT IPSec traffic. NAT happens BEFORE IPSec in the PIX, so if you the traffic IPSec nat it will never match your crypto access list and will not be encrypted.

This, however, should not stop the tunnel of Phase 2 of the course of construction, they would stop flowing above the tunnel, traffic, so you still have a problem somewhere. What I'm guessing, is that the Sonicwall (SW) has a different encryption-defined list access, it must be the EXACT OPPOSITE of what is configured on the PIX. In other words, the SW should be encrypting the traffic of "remotevpnLAN-24" "intranet/8", make sure that the subnet mask ar ETHE same too. "

To answer your questions:

1. it simply means that the PIX has not received a response and is to retransmit the last ISAKMP packet. The process_block simply means that the PIX has dropped a package that was to be encrypted because the IPSec tunnel has not been built. If you get the tunnel built, these messages will disappear.

2. the 3 first static does not appear to be linked to the tunnel IPSec, if they are simply to access a server inside, then they will not affect this VPN tunnel. The last of them should be deleted, as I already said.

3. for traffic initiated from inside the PIX, the order is incoming ACL, then NAT, IPSec processing. That's why your OUTGOING ACL must allow traffic first, then your NAT 0 statement refuses to be NAT had, then the encryption function is the traffic and the number.

4 do what I said above :-)

If you still have no luck, re - run debugs, but initiate traffic behind the Sonicwall, in this way the Sonicwall will try and debug of build that the tunnel and you will get more information on the PIX. Mainly, we'll see what traffic model the SonicWall is configured to encrypt (you don't see if the PIX initiates the tunnel).

IPSec tunnel is disabled

We have 3 IPSec tunnel set up between the cisco 1760 router and PIX 515e. IPSec tunnel is down by intermittent & son come only after compensation isakmp crypto & clear crypto its next to the router.

do we need to configure something else in router and end of pix so that tunnels are still in Active state (QM_IDLE).

Looks like the PIX loses its connection and the router is unable to say that the PIX has dropped.

Try the isakmp keepalive on both devices configuration but also check network links extended features.

See you soon,.

RVL200 IPSEC: run together or some data traffic by tunnel, possible?

Is it possible to run all the / some data traffic via an ipsec connection in tunnel using the RVL200?

I have managed to connect routers ipsec RVL200 and RV042 and are able to connect to servers/computers behind it.

Now I want to run some or all traffic through the ipsec tunnel for computers that are on the 192.168.1.0 network RVL200 subnet.

Main office - router RV042 - 10.200.62.1

-Router RVL200 - 192.168.1.1 remote desktop

I am using the Advanced Routing option to add static routes, but I'm not 100% sure if I am setting up roads properly.

To give an example of routing queries DNS for HOTMAIL.COM [65.55.72.183]:

Destination IP - 65.55.0.0

SM - 255.255.0.0

GW - 10.200.62.1

Hop - 1

LAN - interface

For some reason any that doesn't seem to work. I also tried to use the setting of the WAN interface and tested - it does not work.

Is this possible? If someone has tried to do that, I'd be very interested to know how to configure it.

See you soon.

MP

Linksys RVL200 or RV042 does not support the split DNS to the IPsec tunnel, which seems to be what you need. You might consider to upgrade the routers for the Cisco Small Business RV0xx routers that do not support DNS split on IPsec.

Backup Tunnel VPN Firewall even

I have 2 VPN tunnels on the same worm 6.3 pix firewall (5) tunnels goes to the remote site. On the remote site, there are 2 internet circuits has a primary and a secondary. The primary circuit goes to one tunnel on my firewall and secondary goes to another tunnel on my firewall that only appears when the primary circuit breaks down.

We notice that when the primary circuit falls backup on the pix firewall tunnel is up but the traffic stops flowing after a few minutes and I need to erase the crypto isakmp before traffic starts to flow again.

Am I missing something with my setups when VPN is similar to this type of installation?

You must configure the tunnel dpd so that once the main tunnel breaks down the PIX must erase the SA for this tunnel.

now based on the code that you have 6.3 (5), keepalive feature is not available

Problem of process ISAKMP Tunnel VPN

I configured two tunnels of the separate two PIX to a Cisco 3000 Concentrator.

The settings on the two PIX on ISAKMP polocies and transformation-games are the same. However, establishes a single tunnel, and the other fails.

I think the problem is at the end of 3000, but I am unable to prove it, that I do not have access.

The PIX with the tunnel telling the following debug output (debug crypto isakmp, debug crypto ipsec). The reason the SA is deleted mentions the 3000 having a bad set transformation in politics?

It seems that phase as 1 (ike) sa is be created without error. I think that the problem lies in the phase 2 (ipsec) his. Can you put the cryptographic cards relevant and ACLs cards referring to the PIX that fails and the pix who succeeds? That may give a clue as to what is the question.

Claire do not fragment Bit - PIX

I realize that IOS has the ability to clear the df bit but it the PIX has this same feature? I am currently working with a Netscreen counterpart which has a much larger pool of "tweaks" at its disposal that I noticed on my PIX PIX OS 7.2 535. My issues are with anti-replay and I can't even turn off the anti-replay feature without disabling IKE, and we can not all our peers VPN manual configuration.

My basic question is if you clear the df bit is possible on the PIX?

Thank you all for the research/sponsor.

Chris,

Yes, it is possible to erase the bit df on the Pix to IPSEC Tunnel in version 7.2.

The command is:

Crypto ipsec df - bit

Help with vpn pix 501

I'm setting up a cisco pix 501 vpn tunnel but will have questions. The Firewall works although I am able to get out of the internet, but the VPN does not work. On the primary side, I see that the tunnel is up and the traffic is sent but not received.

Currently I'm sitting at the secondary location but don't know what the problem maybe. Anyone know what I have wrong which could prevent the data to send from this device?

Here is my config

Here's my config if it would help

Cannot reach the destination of an IPSec tunnel through another IPSec tunnel

Hi all

I have a PIX 515E version 8.0 (2).

I have two remote sites connected to this PIX via IPSec tunnels.

Each remote site can reach local networks behind the PIX, but I can't reach remoteSiteB remoteSiteA.

Thus,.

SiteA <----- ipsec="" -----="">PIX1 SiteX <---------------->10.0.8.1 10.30.8.254

SiteB <----- ipsec="" -----="">PIX1 SiteX <---------------->10.0.8.1 10.138.34.21

SiteA can ping SiteX

SiteB can ping SiteX

SiteA cannot ping SiteB

SiteB cannot ping SiteA

If I do not show crypto isakmp ipsec his I see appropriate subnets:

Tag crypto map: CRYPTO-MAP, seq num: 4, local addr: 203.166.1.1

Inside the package décapsulés does not match policy negotiated in the SA. The package indicates its destination as 10.138.34.21, its source as 10.30.8.254 and its Protocol 6.

My question is really what I have to do something funky to allow traffic to pass between the two tunnels?

Hello

This could be much easier if we have seen the real configurations.

But here are some things to be confirmed in the configurations (some of them you mentioned above, but I still quote once again)
- Make sure that each firewall, you set the appropriate VPN L2L ACL
- Make sure that you have configured NAT0 on the central PIX "outside" interface for the Site A and Site B
- Make sure the Central PIX has "same-security-traffic permit intra-interface" configured. This will allow the Site traffic to enter the Central PIX 'outside' interface and head back on the same interface to Site B. And vice versa.
To view some actual configurations that may be required provided everything else is ok. (I assume that all devices are Cisco)

Hello

I have the following configuration:

Is there a way to get/collecting snmp from inside the int on PIX2?

Concerning

Fredrik,

Add (in config mode), access inside management

This will give you access to the inside ping your pix via the tunnel interface and therefore pick up given SNMP.

Let me know how you go.
