problems with vpn firewall/proxy configuration
Hello
I want to access vpn through firewall/proxy (Client VPN) client-side.
I installed the vpn gateway as firewall pix 515 using Microsoft CA IKE SA.
I want to establish the vpn tunnel to my vpn through a proxy/firewall client.
I tried in some places of vpn client where the firewall acts as a linux machine in which he allowed with the ipsec and NAT esp feature. Its works perfectly. But only one concurrent vpn client. Also the first tunnel vpn disconnects when the second user tries without knowing the first established tunnel.
I heard that we can drive this problem using "NAT Taversal" mode which is available in version ios 6.3 as concentrator 3000 Cisco pix.
I want to know how NAT Traversal can solve my problem in which multiple concurrent users without support nat esp in a configuration only one simultaneous user without support nat esp in a configuration of firewall/proxy or firewall/proxy.
Thank you

The VPN client is able to detect that he's been through a NAT/PAT device on the way to the hub/PIX, and then if both ends support it, they will automatically start NAT - T and encapsulate the IPSec packets in UDP port 4500 packets. These can then be NAT would properly and you will not get disconnections or problems you currently see.
You don't see that a client can connect and customers being disconnected when the other connects it is your PAT instrument cannot process the ISAKMP and IPSec packets correctly. It is a fairly common symptom.
PIX v6.3 code will support NAT - T, should be available in March sometime.

I have two problems with IPSEC VPN, using the cisco client, and a third, which I think could answer here if this isn't strictly associated with VPN.
1. cannot access the internet, while VPN is in place. This can be a problem of client as I * think * I've split tunneling to install correctly.
2. cannot access other networks except the network associated with the inside interface natively.
3. I can not ping to the internet from inside, be it on the VPN or not.
I tend to use the SMDA; Please, if possible, keep the answer to this kindof of entry.

Hey,.
Unfortunately, I do not use ASDM myself but will always mention things that could be done.
You do not split tunneling. All traffic either tunnel to the ASA, while VPN is active
You have the following line under the "group policy"
Split-tunnel-policy tunnelspecified
You will also need this line
Split-tunnel-network-list value
Defines the destination for the VPN Client networks. If you go in on the side of the ASDM group policy settings, you should see that no ACL is selected. You don't really seem to have an ACL in the configuration above, for the split tunneling?
To activate access Internet via the VPN Client now in the current configuration, I would say the following configuration of NAT
VPN-CLIENT-PAT-SOURCE network object-group
object-network 172.17.200.0 255.255.255.0
NAT (outside, outdoor) automatic interface after dynamic source VPN-CLIENT-PAT-SOURCE
In regards to the traffic does not for other networks, I'm not really sure. I guess they aren't hitting the rule NAT that are configured. I think they should, but I guess they aren't because its does not work
I could myself try the following configuration of NAT
object-group, network LAN-NETWORKS
object-network 10.2.0.0 255.255.255.0
object-network 10.3.0.0 255.255.255.128
object-network 10.10.10.0 255.255.255.0
object-network 172.17.100.0 255.255.255.0
object-network 172.18.1.0 255.255.255.0
object-network 192.168.1.0 255.255.255.0
object-network 192.168.11.0 255.255.255.0
object-network 192.168.30.0 255.255.255.0
object-group, network VPN-POOL
object-network 172.17.200.0 255.255.255.0
NAT (inside, outside) static static source of destination LAN-LAN-NETWORK VPN-VPN-POOL
Add ICMP ICMP Inspection
Policy-map global_policy
class inspection_default
inspect the icmp
or alternatively
fixup protocol icmp
This will allow automatically response to ICMP echo messages pass through the firewall. I assume that they are is blocked by the firewall now since you did not previously enable ICMP Inspection.

Problem with "vpn sysopt connection permit.
Hi all
I would like to ask you for advice with "vpn sysopt connection permit". I have a problem with by-pass-access list (acl) in the INSIDE interface. As I understand it and I'm going to use this command, there is no need to especialy allow traffic in the access list for the INSIDE and I can control the filter-vpn traffic. But in my case it's quite the opposite, I want particularly to this INTERIOR acl traffi. When I allow this traffic inside acl L2L tunnel rises, hollow traffic flow vpn-fltr ane acl that everything is OK. But when I do not allow that this traffic is inside of the rule with Deny statement in acl INSIDE block traffic and tunnel goes ever upward. Part of the configuraciton which you can view below.
Please let me know if I'm wrong, or what I did wrong?
Thank you

Hello
The command "sysopt connection permit-vpn" is the default setting and it applies only to bypass ACL interface to the interface that ends the VPN. It would be connected to the external network interface. This custom has no effect on the other interfaces ACL interface.
So if you initiate or need to open connections from your local network to remote network through the VPN L2L connection then you will need to allow this traffic on your LAN interface ACL networks.
If the situation was that only the remote end has launched connections to your network then 'sysopt permit vpn connection' would allow their connections around the external interfaces ACL. If If you have a VPN configured ACL filter, I think that the traffic will always accompany against this ACL.
Here are the ASA reference section to order custom "sysopt"

Problem with VPN Site-to-Site between RV215W and ASA5510
The RV215W is intended to connect a new branch via 3G, but fail.
But when connected to the internet via a cable modem VPN works.
I have set up with the FULL domain name and remote ip address.
Please help me soon as soon as you can.
Thaks a lot.
Henriux2412.
Dear Henry;
Thank you to the small community of Support Business.
I doubt that this VPN site-to-site is compatible with the USB modem broadband Mobile 3 G, but I have when even suggest to verify that the Status field of the map will show your mobile card is connected (status > Mobile network). I've seen a similar problem with a Verizon USB modem where the solution was to change a few settings in their access Manager software ("NDIS Mode - connect manually" has been selected and change this option to "Modem Mode - connect manually fixed), but if this is not your case then I suggest you to check with your service provider about supported VPN site to site on the WAN configuration.
Except that I advise you to contact the Small Business Support Center for more information on this subject, although I don't think they will support

Problem with VPN Site-to-Site between RV215W and ISA550
Hello
I tried to set up a site connection to site between a RV215W and an ISA550 for a whole day without success now, could someone help me with an example of configuration?
I'm new to this kind of configurations and VPN Options of two routers seem very different, with IKE an IPsec on the RV, IPsec and IKE policies, transform the policies on the ISA.
Outputs the Wizards from Site to Site are not either.
The RV215W is intended to connect a new branch via 3G and that it doesn't have a fixed IP address.
Subnet the ISA is 10.10.11.0/24 VR 192.168.100.0/24
Thanks for any help in advance!

Hello
I check all the screenshots and you must:
-Disable the PFS on ISA500 (screenshot of ISA500 of a second)
-Enable IPsec on ISA500 (first screenshot of ISA500)
-Activate the VPN on RV215W (first screenshot of RV215W) policy
And iniate the RV215W VPN
I hope that this step will fix the problem
Thank you

Problem with VPN compatibility between 2811 and 2911
Hello
I would ask anyone had problems with the implementation of a VPN tunnel between 2811 and 2911?
The IPSec VPN is established, but for some reason, I cannot ping the side LAN across LAN to the other end of the VPN router?
All experience would be highly appreciated
Thank you
IPSec VPN can be smoothly between routers cisco (and not nesesserely cisco) set up, so there should be no problem in your case.
If you say that this tunnel is established successfully, then the problem most likely related to routing problems between sites or incorrect configured crypto-acl. Check if the hosts located on both sites have correct routing information on how to get to subnets on the other site.
Make more accurate assumptions, it would be helpful that you provide config on both sites and describe your topology.

Problems with the file Proxy PAC and Intranet access
Dear users of the Forum,
Maybe someone has some advice for the following problem:
We have configured the IE8 from our corporate customers of Windows 7 64 bit use a proxy configuration script (e.g. http://proxyconf.test.de).
Now sometimes sporadic, especially in the morning when the client boots, the customer/user cannot open the pages of the INTRanet from our corporate network.
But the opening of Web pages works. After erasing the Temp. Internetfiles INTRAnet access works again.
Further, we discovered the following:
Whenever the problem occurs, there is a file in the Temp. Internetfiles named "proxyconf.test.de/" (type CACHE file), which has a size of 0 KB and is empty.
Once we delete it and restart the browser, access INTRAnet also works again.
Add to this empty file, there is the default.pac of our Proxy Server in Temp Internet files, which contains the correct data.
I understand that Windows updates cache the PAC file locally, but I couldn't find out why empty this file proxyconf.test.de was created.
This happens with many customers and users.
Does anyone have a tip for this problem?
Thank you
CK
PS:
in the CAP file he itself, there are two types of entries:
-When opening the Intranet Pages use a Proxy Server
-When opening to something else, use the Proxy Server B

Problems with VPN tunnels after the upgrade to PIX 7.0
It seems that Cisco has revamped the VPN process on the new Version of PIX 7.0.
After I've upgraded, I noticed that AH (i.e. ah-sha-hmac, ah-md5-hmac) was no longer supported and all my container transformation games OH no were not converted.
Another question, if you have enabled on Versieon 6.3, names when you upgrade, tunnel groups will be created (formerly "identity isakmp crypto, crypto key
isakmp peer ') which will include a hostname (hostname of identity) instead of IP as it was to the point 6.3. Guess what... Nothing works! Having to delete and recreate it using the IP address. See an example...
tunnel-group OTHER_END type ipsec-l2l
IPSec-attributes tunnel-group OTHER_END
pre-shared-key *.
The above does not work... Having to recreate using the IP address mapped to OTHER_END...
tunnel-group 2.2.2.2 type ipsec-l2l
2.2.2.2 tunnel-group ipsec-attributes
pre-shared-key *.
Furthermore, I have problems with my racoon and freeswan extranet... Did someone recently updated with success and other gateways VPN provider (i.e. checkpoint, Freeswan and Racoon) work?
We found the solution for this problem. It appeared that the perfect forward secrecy is enabled at the other side. If a 'card crypto outside_map 10 set pfs' is necessary. With the pix 6.3 version that appears not to make the difference, the vpn works even with pfs disabled on the side of pix.

I use two ASA 5540 in failover active-standby configuration. These boxes (primary and secondary) are used to establish some L2L and VPN RA (remote access). The active area run the OSPF process.
The problem is when the failover (blocking just to the bottom of the active area, or "active failover" running in a secondary zone) all L2L be restored in a secondary zone. The only way I can do this (re-connect) removes the configuration of IPP (Reverse injectable way) (for example. ("no card crypto rprbbe_map 3 don't set reverse-road") and the configuration of IPP ("card crypto rprbbe_map 3 Road opposite the value"). After this the connection is re-established.
In RA guests the session persists on a failover event, but the customer loses access. To resolve this problem, the customer needs to disconnect and reconnect.
Anyone has any experience with this kind of (L2L and RA) VPN configuration using failover?Behavior seems buggy.
What version do you use?

Problem with VPN connection via a wireless card broadband Verizon Cisco VPN air
I can't access any device on my network via RDP or applications via the host file - forwarded servers from my 64 bit Windows 7 laptop using wireless broadband Verizon and customer VPN Cisco 64 bit 5.0.7.290. I can connect easily via a LAN wired connection from home using the same laptop computer and client VPN and RDP.
The VPN client connects to the server VPN (easy VPN on Cisco 2821 router) on the broadband wireless connection (I can see it in the GPMC on the router) but it will pass no data. I can't ping anything in the field, or external IP address. When I try to ping the laptop, it drops off the VPN (completed peer connection).
The laptop is a Dell M4500 running Windows 7 Ultimate 64 bit OS. The VPN client is stated, rev 5.0.7.290. The card internal wireless broadband is a QualCom 5620 (EV-DO-HSPA) system (Gobi 2).
What must I do to get this configuration to perform and log as does the wired connection?
Tim Carlisle
The Systems Manager
Post edited by: Timothy Carlisle recently I discovered that the Cisco 64 bit client VPN running on my Dell Precision M6500 (Windows 7 64-bit OS) was able to connect properly using the WiFi on my iPhone 4S (Verizon Wireless). It will also connect when attached to the laptop via a USB cable. Once I discovered this, I was then able to do the same thing on the laptop that spawned this discussion, by attachment for Blackberry "BOLD" from the boss after the download and installation of a new Verizon Wireless Access Manager utility that has allowed to select the device (Blackberry) for installation. I think that enabled us to bypass the wireless cards Gobi2 on two laptops and the factory installed Dell Connection Manager software which was not compatible with the Cisco VPN 64 bit client software. As much as I fear here, this new method (hotspot of Smartphone and attachment) is the way to go for us and has solved all the problems of connectivity distance for us. Thank you to all who have contributed to this discussion. Tim Carlisle
The Solution to the debate has been captured in this Document: -.
https://supportforums.Cisco.com/docs/doc-18721
We fought with the same question for quite awhile before finding that there seems to be a default setting in the Verizon Access Manager software that plays well with the Cisco Client.
In VZAccess Manager, select Options | Preferences. Connectivity options, the default setting for "NDIS Mode - connect manually" was chosen. Change this option to "Modem Mode - connect manually" seems to have completely addressed the issue. We can now connect to the WWAN, establish a Cisco VPN session and have connectivity.

I have a century to site IPSec VPN 3005 concentrator with a PIX.
On the PIX config is:

the object-network 172.16.1.1 host
network-object host 172.16.1.2
network-object host 172.16.1.3

address for correspondence outside_map 10 card crypto VPN1
card crypto outside_map 10 peers set a.b.c.d
outside_map crypto 10 card value transform-set ESP-DES-SHA
...
...
The hub, I have two address lists that are used in the definition of VPN:
LANHosts: 172.16.1.1/0.0.0.0
172.16.1.2/0.0.0.0
172.16.1.3/0.0.0.0
172.16.1.4/0.0.0.0
Distance: 10.1.0.0/0.0.0.255
10.2.0.0/0.0.0.255
Now the problem. When an IPSec security association is initiated from a host in the range 10.2.0.0 to 172.16.1.1 for example the IPSec Security Association is not created. When I got the boot from the host 172.16.1.1 to a host in the 10.2.0.0 range, it works well. Everything works perfectly, so between the range 10.1.0.0 and hosts all IPSec SA are created little matter which side starts the IPSec Security Association.
Why won't an IPSec security association, initiated from the 10.2.0.0/24 range upward? What's wrong?
the problem may be the way in which you have configured the list of networks. I guess you are trying to restrict access between private sites.
If so, the list of the network should be the whole subnet not an individual host, then set up the filter to restrict access.

Problems with VPN PIX 525 Lan-to-Lan Cisco 2610XM
Hello world
I have a VPN with PIX 525 versi problems? n 7.2 (1) and Cisco 2610XM Version 12.3 (18). When start the PIX, all tunnels works well, but 6-7 days, some of the tunnels do not work properly. Traffic passes the tunnel with some networks, but not with all networks. Sometimes the tunnel descends and it is imposible to go upward.
Attach them files are the "debug crypto isakmp" in both devices.
Thank you and sorry for my bad English
If your configuration of the tunnel on router 7500 series, the tunnel interface are not supported for politicians to service in the tunnel interfaces on 7500

Problems with VPN on a PAT router
Hello
I have problems to make my VPN to work. I read through various examples of configuration, but don't always have it work properly.
Scenario: connection with the Cisco VPN Client to my router from outside.
Router works like NAT/PAT overload. Internet: Internal FA0/1 network: FA0/0
Problems: connection is working without problem, but I can't access anything in the network behind the router. Some hosts ping sometimes works, sometimes doesn't.
Does anyone have an idea of what could be the problem and what wrong with my setup?
Thanks in advance!

endJenny,
The NAT config is a little weird, you list 1.
List 1 is everything inside. (so all traffic inside subnet must be natted).
You must create an extended access list and create the entry
IP access-l ext 195
10 deny ip LOCAL_ADDRESS LOCAL_MASK VPN_POOL VPN_MASK
1000 ip LOCAL_ADDRESS LOCAL_MASK perm all
and apply that list to NAT overload.
This gives a try and let me know.
