• Just as a reference: how to FIX the annoying 'White Screen Of Death"with Silverlight and"Access denied"error with computer management.

  Well, I just hope that someone who has met these two mistakes will find my dose. It might save a lot of pointless research on the net.

  SYMPTOMS:
  -When you try to open a Silverlight application in your browser (Firefox, Chrome, IE, etc), your browser displays only a white area. When you right click on the white area, you can click on the Silverlight properties.
  -If you try to start "Computer management" by clicking on the 'My Computer' icon and select 'Manage', you get the following error: 'access denied '.

  CAUSE:
  The following errors are usually the result of a bad environment variable. In this case the "windir" environment variable does not work correctly. You can try running the management of the computer to start > run and entering:
  %windir%\system32\mmc.exe/s %windir%\system32\compmgmt.msc

  Notice the between the characters of percentage windir environment variable. If you run the above code, you will probably get an error saying that MMC cannot open the file. Look closely at the path, it's back!
  You will probably find any % somewhere.

  What actually happened here is the variable windir made reference to another variable: systemroot
  Why this creates problems, I'm not sure. Also, I don't understand what made then variable windir change.

  SOLUTION:
  -From your desktop or Explorer: right-click on "My computer" and select "Properties".
  -Click on the "Advanced" tab and then click "Environment Variables".

  http://pcauthorities.com/images/advanced-system-properties-XP.jpg

  -Did the windir variable. Together to "C:\Windows" do not think that it is already set to "C:\Windows", because windows then tells you. Double-click it to know for sure.

• RVL200 - SSL VPN and firewall rules

  Forgive my ignorance, but I have been immersed in the configuration of this device RVL200 to allow Remoting SSL VPN to a customer site, sight unseen.  I have the basics of the VPN set up in config, but now move the firewall rules.  We want to block all internal devices to access the Internet, but I don't want to cripple the remote clients that will be borrowed by blocking their return via the SSL VPN traffic.  This leads to my questions:

  (1) a rule of DENIAL of coverage for all traffic OUTBOUND will prevent the primary function of the VPN (to allow the administration away from machines on the local network)?

  (2) if the answer to #1 is 'Yes', what ports/services do I need to open the side LAN?

  (3) building # 2, configuring authorized outbound rules apply only for VPN clients, rather than all the hosts on LAN?

  (4) as the default INCOMING traffic rule is to REFUSE EVERYTHING, do I have to create a rule to allow the VPN tunnel, or guess that in the configuration of the router?

  Here are some other details:

  • The LAN behind the RVL200 is also isolated LAN in a manufacturing environment
  • All hosts on this network have a static IP address on a single subnet.
  • The RVL200 has been configured with a static, public IP on the WAN/INTERNET side.
  • DHCP has been disabled on the RVL200
  • Authentication to the device will use a local database.
  • There is no such thing as no DNS server on the local network
  • The device upstream of the RVL200 is a modem using PPPoE DSL, and the device has been configured for this setting.
  • Several database of local users accounts were created to facilitate the SSL VPN access.

  I worked with other aspects of it for a long time, but limited experience with VPN and the associated firewall rules and zero with this family of aircraft.  Any help will be greatly appreciated.

  aponikikay, there is no port forwarding necessary to the function of the RVL200 SSL - VPN.

  Topic 1. That is not proven. It shouldn't do. The router should automatically make sure that the SSL - VPN router service is functional and accessible.

  Re 2. No transfer necessary. In addition, never before TCP/UDP port 47 or 50 for VPN functions. The TCP 1723 port is used for PPTP. UDP 500 is used for ISAKMP. You usually also to transmit TCP/UDP 4500 port for IPSec encapsulation.

  Let's not port 47. ERM is an IP protocol that is used for virtual private networks. It is a TCP or UDP protocol. GRE has 47 IP protocol number. It has nothing to do with TCP or UDP port 47. TCP and UDP are completely different protocols of free WILL.

  It goes the same for 50: ESP is the payload for IPSec tunnels. ESP is the Protocol IP 50. It has nothing to do with TCP or UDP port 50.

  'Transfer' of the GRE is configured with PPTP passthrough option.

  'Transfer' of the ESP is configured with IPSec passthrough option.

• SSL VPN and Windows 7 32 bit

  I wonder if it is possible to have 2 SSL VPN client running simultaneously at the same time. When I'm working out of the site, I have to do the following:

  1. I call Array SSL VPN network to connect to the corporate network. I need it to be able to read emails.

  2. I invoke some other developed internal SSL VPN client to connect to the customer's network. This is necessary to get access to access the Citrix customer environment.

  When I run the 2nd SSL VPN, my vision behaves erratically as the gel or the loss of connection to the exchange server.

  SSL VPN network table is a SSL VPN split, which means that it routes web traffic of the company and nothing else.

  Developed internal SSL VPN is configured to route specific IP range.

  I wonder if there is any limitation in Windows 7 32 - bit OS that prevent me to simultaneously run 2 SSL VPN clients.

  Appreciate your comments and your support.

• RVL200 SSL VPN: cannot access a remote LAN with iPad2

  RVL200 firmware 1.1.12.1

  iPad2 cannot access any device on the Remote LAN despite the closed padlock icon.

  Is there another App needed? Or how to debug SSL VPN?

  Emmanuel,

  Were you able to access the LAN devices? Also, have you connected using a Mac or a PC successfully to verify that the devices are available? Sometimes antivirus and firewall software can block access to devices from a remote IP address.

• SSL VPN and routing problem

  Hi all

  I have a strange architecture including VPN and I have a few problems that I am not able to solve:

  -J' use the ssl vpn gateway to allocate internal IP addresses of the local network described in the schema (8.8.2.0 or 8.8.3.0 according to the tunnel-group network.

  -The purpose is for vpn clients directly access the internal network.

  This works very well if there are strictly internal communications within the network. But recently, we have installed an application that needs to access both networks. No problem, I thought, but I was wrong, there seems to be a problem of routing inherent in the architecture in place.

  Let me explain the problem:

  -When I access the VPN, for example I will gave the 8.8.3.5 ip address.

  -Im running the application that needs to open a page on the web server, located at 8.8.2.120

  -l'asa receive my tcp syn datagram and forward it directly to the directly connected interface fa0/1 (based on the routing table)

  -the web server returns the response, but he sends on its default gateway which is the cisco 6509.

  -6509 it sends its vlan svi 2000

  - and finally the ASA it receives on its interface fa0/2 but seems he falls as she opened a tcp on fa0/1 connection and receives the response on fa0/2.

  I want it's traffic by tunnel to bypass the connected roads and transmit it to a default gateway of tunnel. This would ensure that the path for the request and the response would be the same.

  I would like to know if there are orders of debugging for routing decisions validate my theory?

  Do you know of any response to solve this problem?

  Thanks a lot for your help.

  When you configure the TCP State derivation always think ' which way is the SYN package coming?

  Routing failed messages always have source and destination, are of course copied the entire message?

  BTW, instead of letting clients SSL addresses attributed to vlan2000? Why not give them a separate subnet and the road back via correct interface?

  I would also check your config and the routing :-) table

• SSL VPN and RSA on demand tokens

  Hello

  I tried scouring the web and can't find anything on how to get this working. We have our SSL VPN using RSA atm but would also like to be able to use the version on request as well.

  I was not able to find any doco on how to enable this.

  Any help in pointing me in the right direction would be thank you much

  Kris,

  Any name of username/password authentication is (nearly) transparent to ASA.

  ASA or any device authentication sends a request containing the credentials to the back-end server that meets the acceptance, rejection or in some cases, a challenge.

  A notable exception side RSA's Adaptive Authentication (sometimes called tokenless) that requires further customization on the SAA.

  The people on the side RSA are a smart bunch they can usually answer how their solution integrates with different vendors/solutions. If I am that prepare properly (that I could find with a quick query) there is no additional considerations side ASA save to set the right server and point it as the service of the methods (and if any NAT/ACL to allow users access to the server where you can request the token to send - usually in a zone demilitarized).

  I am based on:

• site2site distance-VPN and access-PIX - no way?

  I have,

  I have a problem wrt site2site & VPN remote access on a PIX:

  My setup is as follows: PIX (6.3) puts an end to two a site2-site VPN and also should the remote access service clients using the client VPN Cisco (4.0.x).

  The problem is with remote access VPN clients, obtain an IP address on their VPN interface, but customers cannot reach anything. (Please note that the site2site VPN runs without problem)

  To be precise (see config-excerpts below):

  The customer, who has 212.138.109.20 as its IP address gets an IP 10.0.100.1 on his card-VPN which comes from the "vpnpool of the pool.

  configured on the PIX. This customer relationships to reach servers on interface 'inside' of the PIX as 10.0.1.28.

  However, the client cannot achieve * nothing *-a server on the inside or anything like that (e.g. Internet) outside!

  Using Ethereal traces, I discovered that the packets arrive inside interface coming 10.0.100.1 (IP address of the)

  VPN - client). I also see the response from the server (10.0.1.28) to 10.0.100.1. However for some reason any package does not thanks to

  the PIX to the customer. PIX-newspapers also show packets to and from the VPN client to the inside interface - and * no. * drops. So to my knowledge the packets from server to the VPN client really should be done through the PIX.

  I have attached the following as separate files:

  (o) the parts of the PIX config

  (o) packets showing PIX-log between the VPN client and the server (s) on the interface inside

  (o) ethereal-trace done inside the watch interface also packets between VPN client and server (s)

  I have really scratched my head for a while on this one, tested a lot of things, but I really don't know what could be a problem with my

  config.

  After all, it really should be possible to run site2site - and on the same PIX VPN remote access, shouldn't it?

  Thank you very much in advance for your help,.

  I think that your problem is in your ACL and your crypto card:

  access-list 101 permit ip 10.0.1.0 255.255.255.0 10.0.2.0 255.255.255.0

  access-list 101 permit ip 10.0.0.0 255.255.255.0 10.0.2.0 255.255.255.0

  access-list 101 permit ip 10.0.3.0 255.255.255.0 10.0.2.0 255.255.255.0

  access-list 101 permit ip 10.0.1.0 255.255.255.0 10.0.100.0 255.255.255.0

  correspondence address 1 card crypto loc2rem 101

  This means that this map correspond to these addresses. But your dynamic map is one that must match 10.0.100.0, 10.0.1.0 traffic because your pool local ip is 10.0.100.x. I think what is happening is that the return traffic from the lan to vpn clients trying to get out of the static tunnel, which probably does not exist (for the netblocks - you probably have a security association for each pair of netblocks, but not for vpn clients) and so do not.

  I would recommend adding these lines:

  access-list 105 allow ip 10.0.1.0 255.255.255.0 10.0.2.0 255.255.255.0

  access-list 105 allow ip 10.0.0.0 255.255.255.0 10.0.2.0 255.255.255.0

  access-list 105 permit 10.0.3.0 ip 255.255.255.0 10.0.2.0 255.255.255.0

  no correspondence address 1 card crypto loc2rem 101

  correspondence address 1 card crypto loc2rem 105

  Then reapply:

  loc2rem interface card crypto outside

• SSL VPN and ipsec

  For CISCO1841-SEC/K9, ssl and ipsec vpn connection vpn how, we can make and? The datasheet is not any specific number.

  Thank you.

  Dijoux

  With the PIX and ASA, the number of peers is specified in the license and limited to the number specified in the license (so in support of peers, you must update the license). From my experience of the IOS application does not bind the number of peers for what anyone in the license. So, if you buy a feature set for IOS router supports IPSec/SSL VPN, then this is your license for IPSec and SSL peering (no separate license is required).

• SSL VPN and Dynamic DNS - ddns on IOS

  Hello

  I am configuring a VPN SSL via SDM tunnel on a 877 router. The router gets the dynamic public IP address from the ISP, so I configured DDNS for remote access to the router. I would like to know if it is possible to configure the SSL VPN to support dynamic IP via SDM o CLI.

• Difference between webVPN, SSL vpn and ipsec client

  Hello

  We just bought an ASA5510 and I am trying to understand the difference of the possibilities mentioned VPN. Can anyone describe the differences and use scenarios of all types of remote access vpn of the asa?

  Thanks in advance.

  Rgds,

  Rasmus

  Hi Rasmus,

  They use different SSH and IPSEC protocols, and there is also of course in terms of security.

  SSL is easy to deploy than ipsec. Imagine that you have 200 + users and to connect to the vpn, you must give them the pcf file and client software, which is not required in the case of SSL.

  Kind regards

• SSL VPN and ZFW

  I came across a problem with the IOS from Cisco 881 15.1 M (or 12.4T2 also): Firewall area based blocks access to the anyconnect customer. Interface SSLVPN-VIF0 there but no way I can put it in any area. So, if I idsable ZFW - all right... I found several cases with the same problem - no solution from Cisco. CBAC is not a deal.

  A certain dissapoitment... If the same question will be with ASA5510 - I guess that $20K will go at the checkpoint.

  It should work fine.

  With Anyclient, the traffic will come through the WAN interface, then virtual-model and then only to the local network of the interface. So the solution is that you must create a box and asscoiate area to the virtual model.

  Given that the virtual model is no not part of any zone, anyclient traffic does not pass through the virtual model.

  Basically, we will have three areas now-, sslvpn entry and exit.

  Just do the following for these pairs of area

  in - box sslvpn > allow all IP traffic

  sslvpn area - to > allow all IP traffic

  off - box sslvpn > allow all IP traffic

  sslvpn out area - > allow all IP traffic

  You might be specific for traffic, if you know what is the IP address of anyclients.

  This should solve the problem.

  What is the syntax correct for this line of code to make this work?

  Thank you.

  You can use string to instances of the target values, if you use the support rating:

  Should be able to access their machine if they are connected.

  Just make sure you know their ip address which is attributed to their SSL VPN, and also if they have a personal firewall installed on their computer, it allows access (or off).
