OPC Tunneller

Any issues with Matrikon OPC Tunneller and Labview DSC?
Here is the answer I got from Matrikon, just want to hear if there is any experience here.
Hi Bob
Tunneller has no known issues with LabView OPC client. Tunneller tends to need very little configuration (in fact, only the IP address is needed) in order to work correctly. If you run into anything during the installation or configuration please let us know and we can assist further.

I went to site the next day after posting this and tested the Tunneller client with the site system. I had talked to the IT people prior to leaving and as long as you know all the right settings it makes using OPC clients in DSC very easy when a firewall is in place.
Once the Tunneller is open, the OPC server of interest appears on your local machine when browsing from your LabView project.

Problem to connect with OPC Server opc.sinumerik.machineswitch using DS_Open

Hi,
I want to connect to an Siemens OPC server type opc.sinumerik.machineswitch using DS_Open calls (CVI 6.0) to read few tags. Running my client software (as well as the NI- sample test client) locally on the same computer as the server the connection works and I can access the tags.
Running the client-software on a remote PC then the DS_Open call "hangs-up" (not even an error message). All the DCOM settings etc should be ok, since I can access the tags using the Siemens Client OPC-Scout as test client.
I have used the same calls in several previous applications and it works with other servers (Bachmann, WinCC), so I am pretty sure that I use the correct URLS etc.
What can be the reason for a specific incompatibility?
Any idea is highly appreciated.
Cheers,
Ronald

Hi Roland,
as experience shows, Remote DataSocket is hard to implement.
The best way to implement this communication is the following:
First of all, check the DCOM -Settings
Using OPC via DCOM with Windows XP
http://www.opcfoundation.org/DownloadFile.aspx?RI=326
Use the “NI-OPC Server” to create a tunnel between the Siemens OPC server and your PC.
Install the NI-OPC Server on your PC and use the “OPC DA Client Driver” to access the tags on the Siemens OPC server.
After that you can access the created tags in the NI-OPC Server with CVI and DataSocket.
Please download the NI OPC Servers Evaluation-Version to test communication.

OPC URL features

Hello
Can any one please explain this OPC URL (what each part mean?)
opc://localhost/Tunneller:ric841x1si.da.1\\\ric841x1\66TI1450
I do not understand these parts “Tunneller:ric841x1si.da.1” and “\\\ric841x1\66TI1450”
Please let we know if there is a link for more advance tricks for OPC URL
I am getting this error:
1/22/2007 10:41:34 AM Err Code: -1967259646 SourceataSocket Connect.vi
Error: Parsing URL.<ERR> Addtl Txt: Multiple OPC Items Monitor
Let me know if you know what error is this
Thank you
Amit

Hello Doug
First of all, thank you for your information on OPC URL.
Actually, this is first time I am using OPC with LabView, and I am looking older application which has OPC URL. I wanted to understand how OPC URL address works.
By reading some document I understand some part of the URL but not fully.
You have explained very clearly what I am looking for.
"Tunneller:ric841x1.osi.da.1" is the name of the OPC server ( I am confuse with colon ‘:’ and point ‘.’)
“ric841x1" is most likely a folder within this particular process for organizational purposes
"66TI1450" would be an individual register or data item
Again great help, thank you for that.

IP Phone SSL VPN and Split tunneling

Hi Team,
I went throught the following document which is very useful:
https://supportforums.cisco.com/docs/DOC-9124
The only things i'm not sure about split-tunneling point:
Group-policy must not be configured with split tunnel or split exclude. Only tunnel all is the supported tunneling policy
I could see many implementation when they used split-tunneling, like one of my customer:
group-policy GroupPolicy1 internal
group-policy GroupPolicy1 attributes
banner value This system is only for Authorized users.
dns-server value 10.64.10.13 10.64.10.14

ip local pool SSLClientPool 10.200.18.1-10.200.18.254 mask 255.255.254.0
access-list split-tunnel remark split-tunnel network list
access-list split-tunnel standard permit 10.0.0.0 255.0.0.0
It is working for them w/o any issue.
My question would be
- is the limitation about split-tunneling still valid? If yes, why it is not recommended?
Thanks!
Eva

Hi,
If you're not using certificates in client authentication then the SSL handshake will complete before the user is requested to authenticate with username/password. If this authentication request fails you will see the SSL session terminated immediately following this failure (as in the logs you provided). Notice the 5 seconds between the SSL session establishment and termination, this is most likely when the user is being authenticated against the aaa server. If the phone is failing authentication against an external aaa-server you'll want to investigate the logs on that server to determine the root cause of the failure. The ASA can also provide confirmation of the authentication request/reject with the command 'show aaa-server'. If you want to see what's going on at an authentication protocol level you can enable several debugs including "debug aaa authentication|common|internal' and protocol specific debugs such as 'debug radius user|session|all' or 'debug ldap'.

IPSec tunnel on sub-interface on ASA 5510

Hello All,
I working on a security solution using ASA firewall and need some technical advice on ASA. Is it possible to setup a IPSec tunnels on each subinterface of a physical interface on ASA 5510?
I would be greatul if someone please reply post this with some details.
Regards,
Muds

Hi Jennifer,
Thanks very much for your reply. I understand where you coming from, but the reason of using sub-interfaces is that, we have only one physical interface on the firewall connected to the MPLS cloud, and we need to setup a seperate IPSec tunnels for each client for security and integrity. In the current scenario, I have static peers and we can easily setup a static route to peer address.
Many thanks for your assistance, please feel free to to advise if you have any other suggestion.
Regards,
Muds

Unable to see logs while using split tunnel for RA

hi everyone,
I have config RA VPN at my home lab using split tunnel.
I can connect fine and able to browse the internet.
When i go to internet sites i do not see logs generated on the VPN ASA?

10.0.0.51 is IP assigned from VPN pool to PC.

Hi Mahesh,
You are using Split Tunnel VPN. This means that you have configured the VPN Client connection to only tunnel specific networks through the VPN Connection while its active. You have probably configured an ACL that contains your LAN network behind the ASA.
This means that only traffic destined to that LAN network mentioned in the ACL reaches your ASA through the VPN Connection.
The Internet traffic of the user or any traffic that is NOT destined to that network in the ACL will simply use the VPN Client users PCs local Internet connection or local network.
This is the reason you are not seeing any of the Internet connections from the VPN Client on the ASA. The VPN Client connection is only configured to forward traffic to the LAN network and pass all other traffic past the VPN Connection through the users local network connection.
If you were to configure Full Tunnel VPN for the user this would mean that ALL traffic would be forwarded from the VPN Client through the ASA and the ASA would control where that traffic would be forwarded and if that traffic would be allowed.
If you want to look at the current configuration on the CLI you would first have to issue
show run tunnel-group
And find the connection that you are using at the moment. Then you would have to check what "group-policy" is configured under that "tunnel-group"
Then you could issue the command
show run group-policy
This would list you the Group Policy configuration for the VPN connection and would show something like this under it
split-tunnel-policy tunnelspecified
split-tunnel-network-list value
The above configuration would show you the ACL that the VPN Client configuration is using to tell the VPN Client what traffic to send through the VPN Connection.
Hope this helps

EZVPN public internet split tunnel with dialer interface

I have a job on where I need to be able to use EZVPN with split tunnel but still have access to an external server from the corporate network as the external server will only accept connections from the corporate public IP address.
So I have not only included the corporate C class in the interesting traffic but also the IP address of the external server.
So all good so far, traffic for the corporate network goes down the tunnel as well as the IP address for the external server.
Now comes the problem, I am trying to send the public IP traffic for the external server out of the corporate network into the public internet but it just drops and does not get back out the same interface into the internet.
I checked out this procedure and it did not help as the route map counters do not increase with my attempt to reach the external router.
http://www.cisco.com/c/en/us/support/docs/security/vpn-client/71461-router-vpnclient-pi-stick.html
And to just test the process, I removed the split tunnel and just have everything going down the tunnel so I can test with any web site. I also have a home server on the network that is reached so I can definitly reach into the network at home which is the test for the corporate network I am trying to reach.
Its a cisco 870 router and here is the config

Thanks for the response.
Not sure how that would help as I can connect into the internal network just fine, but I want to hairpin back out the interface and surf the internet from the VPN client. The policy route map makes the L10 the next hop and it has NAT.

How to read enumerated values from an OPC server via Datasocket

Hi Labviewers,
I am using LV8.2 and I am trying to find if it is possible to read enumerations from an OPC server via Datasocket, not just the values.
I can successfully read a value for an OPC server via Datasocket and I get a value for example 3, is it possible to get the enumeration/string that corresponds to this value i.e. "Open".
Many thanks in advance
Dimitris

Hi Sarah,
With the input type as variant I get the following response:
1                                     <-This is the current numeric value of the parameter
4 Attribute(s):
   'Quality' -> 192
   'TimeHigh' -> 29861723
   'TimeLow' -> -665408304
   'Timestamp' -> 39.238E+3
With the Input set to         Enum constant I get no values or strings coming back. With the Input set to             Ring constant I just get the numeric value

I believe when a VPN tunnel is setup there should be one Child sa per subnet. The internal network of 10.65.1.0/24 should be setup with a child sa to the networks that were specified above depending on if there is traffic destined for them. What I am seeing is multiple child sa setup for the same subnet like the example below:
GARPR-COM1-WF01# sh crypto ikev2 sa | i 172.19
          remote selector 172.19.0.0/0 - 172.19.255.255/65535
          remote selector 172.19.0.0/0 - 172.19.255.255/65535
          remote selector 172.19.0.0/0 - 172.19.255.255/65535
          remote selector 172.19.0.0/0 - 172.19.255.255/65535
          remote selector 172.19.0.0/0 - 172.19.255.255/65535
          remote selector 172.19.0.0/0 - 172.19.255.255/65535
          remote selector 172.19.0.0/0 - 172.19.255.255/65535
          remote selector 172.19.0.0/0 - 172.19.255.255/65535
          remote selector 172.19.0.0/0 - 172.19.255.255/65535
          remote selector 172.19.0.0/0 - 172.19.255.255/65535
where for destination network 10.92.0.0/16 there is only one child sa:
GARPR-COM1-WF01# sh crypto ikev2 sa | i 10.92
          remote selector 10.92.0.0/0 - 10.92.255.255/6553
Should this be the case or does anyone have any idea why there is multiple child sa setup for the same subnet?
Thanks

Hi there,
I had same issue with PIX 506E and it was not even a circuit issue and I got ride of it and problem got fixed with PIX515E
I don't know, the device is too old to stay alive.

CISCO ASA 5505 Split Tunnel DNS with Site to Site VPN

I have a working configuration for Site to Site VPN between our head office and a private AWS VPC instance.
The tunnel is active and I can ping the IP address of the remote network and connect to the remote machines using the IP address, but we need to use the FQDN and not the IP. We have a DNS server set up in AWS for any DNS queries for the remote domain name.
My question is whether or not the ASA 5505 supports a DNS split tunnel for Site to Site VPN and how it can be configured.
I can not find where I can interogate the DNS query to be redirected to the VPN tunnel when our domain name is used in a DNS query. Thus, any pings I try with the FQDN of our servers in AWS are failing as they are going to the default DNS, which is the internet.
Can any one point me in the right direction on how to configure this DNS rewrite so that we can access our AWS private cloud using FQDN from our AWS domain rather than an IP address?

Jose, your fix to problem 1 allows all access from the outside, assuming you applied the extended list to the outside interface. Try to be more restrictive than an '...ip any any' rule for outside_in connections. For instance, this is what I have for incoming VOIP (access list and nat rules):
access list rule:
access-list outside_access_in extended permit udp any object server range 9000 9049 log errors
nat rule:
nat (inside,outside) source static server interface service voip-range voip-range
- 'server' is a network object *
- 'voip-range' is a service group range
I'd assume you can do something similar here in combination with my earlier comment:
access-list incoming extended permit tcp any any eq 5900
Can you explain your forwarding methodology a little more? I'm by no means an expert on forwarding, but the way I read what you're trying to do is that you have an inbound VNC request coming in on 5900 and you want the firewall to figure out which host the request should go to. Or is it vice-versa, the inbound VNC request can be on port 6001-6004 ?

VPN Client Tunnel Connection Pix506E

Situation: Trying to connect to PiX 506e for vpn client tunnel. The tunnel shows the following when using the sho isa sa command:
qm_idle 0 0
then after about 3-4 minutes the client workstaiton is receiving error: Reason 412: the remote peer is no longer responding
The same workstation on the same internet connection from the home office is able to connect to an ASA 5505 vpn client with no problems.
I have enabled: nat traversal on the pix506e and tried serveral options on the client side.
The Pix506E also has site to site vpn tunnels that are working without any problems.
Pix Software version: 6.3.5
Any ideas?

Try to connect from a different internet connection and see if you are having the same issue.
Also, turn on the logs on the vpn client and see why it's failing.

Cisco ASA 5505 Site to site VPN IPSEC tunnel to an Clavister Firewall

Hi,
I have weird problem with a Site to site VPN tunnel from a Cisco ASA 5505 to an Clavister Firewall.
When I restart the Cisco ASA 5505 the tunnel is up and down,up, down, down, and I get all strange messages when I see if the tunnel is up or down with the syntax: show crypto isakmp sa
After a while like 5-10 min the vpn site to site tunnel is up and here is the strange thing happening I have all accesslists and tunnel accesslists right I can only access one remote network (Main site Clavister Firewall) trought the vpn tunnel behind the Cisco ASA 5505, and I have 5 more remote networks that I want to access but only one remote network is working trought the vpn tunnel behind the Cisco ASA. I see that when I do this syntax in ASA: show crypto ipsec sa.
They had a Clavister Firewall before on that site before and now they have a Cisco ASA 5505 and all the rules on the main site thats have the big Clavister Firewall is intact so the problems are in the Cisco ASA 5505.
Here is some logs that ASDM give me about the tunnel issue, but like I said, the tunnel is up and only one remote network is reachable in that tunnel.....

Hi,
I'd start by getting the configuration of the remote site related to Local/Remote network configurations and go through them. Even though no changes have been made.
If they are mirror images of eachother already I'd say its probably some problem related to Cisco/Clavister setup
Seems especially wierd to me that one of the error messages includes 0.0.0.0 lines.
I have run into some problems with L2L VPN configurations when our Cisco device just doesnt want to work with the remote end device. In some cases we have confirmed that our networks defined for the L2L VPN are exactly the same and yet when checking debugs on the ASA side we can see the remote end device using totally wrong network masks for the VPN negotiaton and therefore it failed. That problem we corrected with changing the network masks a bit.
Maybe you could try to change the Encryption Domain configurations a bit and test it then.
You could also maybe take some debugs on the Phase2 and see if you get anymore hints as to what could be the problem when only one network is working for the L2L VPN.

Routing Issue for Remote Access Clients over Site to Site VPN tunnels

I have a customer that told me that Cisco has an issue when a customer has a topology of let's say 3 sites that have site to site tunnels built and a Remote Access client connects to site A and needs resources at Site B but the PIX won't route to that site. Has this been fixed in the ASA?

Patrick, that was indeed true for a long time.
But now it is fixed in PIX and ASA version 7.x.
Please refer to this document for details:
