list of required access to vpn
Hello
If we have a LAN to LAN between two cisco firewall and authorized vpn service like IP (ipsec tunnel) must we indivugial-access security policy list? (I had a similar case, where I had to put in a post on the security strategy for port 16000 between two subnets used on the LAN to LAN firewall)
I was under the impression that security policy applies only to the vpn and vpn traffic, we need to specify on the ipsec tunnel (under the Service tab)
Thank you
Enable this command and remove the statement, then try.
config #sysopt VPN-enabled connection
Thank you

Unable to connect to other remote access (ASA) VPN clients
Hello
I have a cisco ASA 5510 appliance configured with remote VPN access
I can connect all hosts on the INSIDE and DMZ network, but not able to access other clients connected to the same VPN.
For example, if I have 2 clients connected to the VPN, customer and CustomerB, with a pool of vpn IP addresses such as 10.40.170.160 and 10.40.170.161 respectively, these two clients are not able to communicate with each other.
Any help is welcome.
Thanks in advance.
Hello
I'm a little rusty on the old format NAT, but would be what I would personally try to configure NAT0 on the 'outer' interface.
It seems to me that you currently have dynamic PAT configured for the VPN users you have this
NAT (outside) 1 10.40.170.0 255.255.255.0
If your traffic is probably corresponding to it.
The only thing I can think of at the moment would be to configure
Note of VPN-CLIENT-NAT0-access-list NAT0 for traffic between VPN Clients
list of access VPN-CLIENT-NAT0 permit ip 10.40.170.0 255.255.255.0 10.40.170.0 255.255.255.0
NAT (outside) 0-list of access VPN-CLIENT-NAT0
I don't know if it works. I did not really have to configure it on any ASAs running older software. There was some similar questions here on the forums for the new format.

Divide access remote vpn tunnel ASA 5520
Hello
I'm setting up a vpn for remote access with split tunnel, but I use an acl extended to match a host and http to destination port, but does not work.
Scenario of
Distance access(10.0.0.122/24)--internet---Cisco ASA(inside:192.168.10.1/24)---ip = 192.168.10.6 - C6509 - 10.0.0.254/24---hote = 10.0.0.31/24
The plot is when I activate the IP service connection or flow ICMP worked. Does anyone have an idea what is the problem? Thank you
Concerning
Split tunneling does not take into account the port information you specify in the ACL, he doesn't care the ip address/network you defined.
If you want to restrict access to ports and IP, you must define your split tunneling with only ip addresses and using a vpn-filter acl in group policy to restrict following the specific ports that you want:
split_acl ip access list allow
access-list allowed filter_acl ip eq
attributes of group-pol
Split-tunnel-pol tunnelspecified
value of Split-tunnel-net split_acl
VPN-filter value filter_acl

VPN to access LAN VPN clinet.
We use a PIX 515 as the hub of a LAN to LAN VPN as well as to access VPN Clinet. Using a multipoint configuration sites speaks (all PIX 501) are able to communicate with each other. However, the VPN to access the 515 client are not able to access the VPN sites has talked about. I think that it is due to the fact that put an end to all tunnels on the same interface of the PIX 515. Is there a way to allow the VPN CLient to communicate with the LAN VPN spoke?
Concerning
PD
Currently, it is not a good way to meet the requirements above. However, add us a new item (or rather, a restriction of relax) for the PIX 7.0 code (to be released in December/January) to allow clients VPN packets 'u-turn' on a Hub PIX to PIX spoke connected via Lan-to-Lan tunnels. The program 7.0 beta is about to begin (may have just begun) so if interested, please contact your local account engineer Cisco. Sorry for the news but help is on the way.

Please note that the configuration is incomplete, I added that relevant changes, you should bring to the allow clients of RA through the LAN-to-LAN tunnel, of course, the LAN-to-LAN settings should match to the other side of the tunnel that is mirror of ACL, NAT and so on.

Hi all:
I was working normally with my NI9024 CRIO to my work. I went home and when I came back the other day. I tried to compile my application to work.
The surprise was that I got a strange message "access denied: the IP address of this computer host is not on the list of eligible access of the target." Now, I can not connect a CRIO device. I tried to reset all the IP addresses in the CRIO and my PC computer. What can I do?.
Yes. This is the solution. I had to uninstall the NOR-RIO software on the target. I have uninstall everything on the CRIO. Then I reinstall the software, but I had also to program the fpga, the host and target. And I also have my IP, on the measure and automatition software. I found a big bug I guess.
Thanks anyway. National Instrument of love. Hope to work there one day.

Access remote VPN question - hairpin
Hello, I did a search before posting this question but I have not found anything specific to my situation.
We have our ASA5520 configured in our main office to allow remote access Cisco VPN client users to access our network. We have a (network 192.168.1.0/24) remote desktop we have a configured on the same ASA5520 VPN IPSec tunnel that allows the use of internal users (in the main office) to access resources on the network remote (192.168.1.0) and vice versa. The problem is that when users connect to the remote VPN access, they are not able to access the resources of the remote office network. We created the nat0 ACL and labour, and split tunnel routing is implemented for users VPN remote network access (if I make a copy of the route on my laptop after connecting to the VPN, I see the road to 192.168.0.0/24 in my routing table). Routing everything is in place to do this, since the IPSec VPN tunnel is up and working. My suspicion is that the question has something to do with the consolidation of these VPN clients.
What else needs to be configured to work? Thank you.
Hi Scott,.
I have a client with a PIX 515E which allows connections to remote VPN and VPN LAN2LAN multiple connections.
We had this problem too... so what I made in my pix was:
TEST (config) # same-security-traffic intra-interface permits (its off by default)
If you use ASDM go to:
Configuration > Interfaces >
at the bottom of this page, there is an option that says: 'enable traffic between two or more host computers connected to the same interface '.
Check and it should work... I hope
I await your comments...
Kind regards.

Access linux VPN client XP host
Hi all
I am running VMWare workstation 6.5 on Linux (Gentoo) with a guest of Windows XP. In the host, I connect to a cisco VPN using vpnc and changing tables of road I have access to the VPN as well as the rest of the local network (including the internet). I want to be able to access the VPN connection (i.e. Access IP address provided by the VPN connection) of the XP client. I know that I can use ssh to tunnel of these connections, but I need to configure a tunnel by ip/port that I connect. At the moment the guest is using bridged networks (it has its own IP address on my local network).
Is the an option of the network configuration in VMWare which will allow the guest to access all interfaces (eth0 and tun0) on the host computer and carry the traffic to these interfaces accordingly?
Thank you
Allistar.
Hello Allistar-
If you configure the client to use the NAT networking, you will be able to access all networks visible to the host (eth0 and tun0) automatically. If you need to expose the ports on the outside guest to the host's network, port forwarding can also be configured through the virtual network Editor.
Good luck

to provide selective access by VPN.
If we have two (add1 and add2) Web servers hosted on the area of the DMZ. and we need to give access to only a more remote VPN client (add1) Web server we do. Because when we configure the remote VPN client using PDM. It will never ask for any particular ip address where this configuration will be applied. He asks only what client VPN interface interacts with.
the current pix configuration should be similar to the one below:
access-list 101 permit ip 192.168.1.0 255.255.255.0 10.1.1.0 255.255.255.0
access-list 120 allow ip 192.168.1.0 255.255.255.0 10.1.1.0 255.255.255.0

If so, then you just need to change 120, i.e. the split tunneling acl acl:
Of
access-list 120 allow ip 192.168.1.0 255.255.255.0 10.1.1.0 255.255.255.0
TO
access-list 120 allow host ip 192.168.1.100 10.1.1.0 255.255.255.0
by changing the acl 120 as shown above, the user remote vpn will accommodate 192.168.1.100 only (all the port/protocol).
Alternatively, you can restrict access to the level of protocol/port. It requires disabling the command 'sysopt connection permit-ipsec' and then create an inbound acl. I would like to know if it is the most preferred and I'll give you an example configuration.
Another point should be noticed is that even if the remote user can only access a server in the DMZ, however, you must also restrict access directly on the server. as the vpn remote user may be able to access other private server resources.

Allowing external IP access via VPN Client
We are looking for our remote VPN users to access an external IP address. Basically once users authenticate when they try to access 202.1.56.19, they should be out nat through the external interface of the firewall. Below is out of the package violated on "vpn ecrypt" tracer and as an extract from the config. On the client, I see that the road to 202.1.56.19 was added, but it does not work.
Please advise more information be required ing. Thank you.

Table of DB tools list: how to access tables that are in the different SQL database?
Hi all
I work on an implementation of database (SQL server) and evaluates the Toolkit OR DB for this project.
One of the requirements is that I need access to the tables that are in two different database
(say Table to 1 DB and Table B to 2 DB).
Our IT guy linked table in DB1 to DB 2 and I verfied this when I use the SQL server management studio.
When DB 2 tables is filled, table from DB1 is also there. I can also do the same thing using MS Access.
Table A of the DB1 is available for me enven if I only connect to 2 DB.
Here comes the problem.
When I use DB tool list Table.vi to access DB2, it does NOT list A table in DB1. It list only the tables in
the database (DB2) which I am connection (using DB tool opened Connection.vi with a file DSN)
So my work around right now is to open a separate connection both DB1 and DB2. However, this approach
obviously creates a problem when I have to access a separate database constantly in my application.
What would be a solution to this? I have search the Forum but only to see a post that is somewhat related to
My question. (And it was published the 2004) Maybe I need to change the code in the orignial VI (DB tool list Table.vi)?
My computer guy told me that he has not met this scenario since he wrote code in another environment such as
VB and others and it has always been successful in linking the different database tables.
I hope my question is clear and healthy because I don't really know much about database terminology.
Any comment or suggestion is appreciated!
Thank you
Chad
Ok. Here is some information that I can work with. Good.
Your COMPUTER staff created a view called "VISUAL_WORK_ORDER".
A view isn't a table. It is a "virtual" table Views are used to collect data (usually) in several different tables.
But I guess that the code inside the DB tool list Table.vi returns a list of tables. Views are not the tables. Then "VISUAL_WORK_ORDER" does not appear in the list.
HOWEVER, this should not really matter. The view is here! And it can be queried like any table. So, you can use DB tools Select Data.VI... and wire in "VISUAL_WORK_ORDER" as the name of the table. This will return the contents of the view. Alto!

Unable to access the VPN Client LAN
I configured a 877 for VPN Client Access. The Client authenticates and connects and receives an IP address off the coast of the pool of intellectual property. However, he is unable to access anything on the IP network.
I have included my router config. The VPN Client is v5.0.05.0290.
Any ideas on what I'm missing?
Can try reverse our ACL VPN-Client, I think that it is written in the wrong way
For example:
VPN-Client extended IP access list
Note * permit VPN Client pool *.
IP enable any 192.168.201.0 0.0.0.255
or more precise
VPN-Client extended IP access list
Note * permit VPN Client pool *.
192.168.1.0 255.255.255.0 ip permit 192.168.201.0 0.0.0.255

No internet access through VPN
Hi, I have the router Cisco 881 (MPC8300) with c880data-universalk9 - mz.153 - 3.M4.bin when users establish a VPN connection to the corporate network, had access to all the resources but no internet access, please help me what else I need to configure to achieve my goal. I don't want to split the tunnel, internet via VPN, users must have. In my opinion, I have put an additional configuration for NAT, but my router not recognize u-Turn and NAT commands on the object on the network.

Cisco IOS - access remote VPN - route unwanted problem
Hello
I recently ran into a problematic scenario: I am trying to connect to a remote LAN (using a Cisco VPN client on my windows xp machine) my office LAN and access a server there. The problem is that I need a remote local network access at the same time.
Remote LAN: 172.16.0.0/16
LAN office: 172.16.45.0/24
Topology:
(ME: 172.16.10.138/25) - (several subnets form 172.16.0.0/16) - (Internet cloud) - (VPN-Gateway) - (172.16.45.0/24) - (TARGET: 172.16.45.100)
To provide access, I configured a VPN to access simple distance on a 1700 series router. It's the relevant part:
(...)
crypto ISAKMP client config group group-remote access
my-key group
VPN-address-pool
ACL 100
IP local pool pool of addresses-vpn - 172.16.55.1 172.16.55.30
access-list 100 permit ip 172.16.45.100 host 172.16.55.0 0.0.0.31
(...)
The configuration works fine, I can access the 172.16.45.100 server every time I need to. However, the problem is that when the VPN connection is connected, Windows wants to somehow rout the packets intended for 172.16.0.0/16 through the VPN tunnel. This is apparently due to a static route that added by the Cisco VPN Client and all other specific VPN routes.
I suspect that the culprit is the IP LOCAL POOL, since when the VPN is connected, debugging of Client VPN log shows something like "adapter connected, address 172.16.55.1/16. Focus on the part "/ 16". I checked the VPN status page and the only road indicated there was "172.16.45.100 255.255.255.255" under remote routes. Local routes was empty.
Is this a known problem I missed the obvious solution for? Is there no workaround apart from the pool local vpn penetrating high-end 10.x.x.x or 192.168.x.x? Thank you in advance for advice or tips!
Hello
The best way is to avoid any overlap between the local network and VPN pool.
Try 172.17.0.0/16, is also private IP address space:

Please rate if this helped.
