with remote computer" This is on a server 2008 r2 platform with a L2TP\IPSEC VPN with a preshared key. I only have mapped port 1701, do I need 4500 and 500 also? What I have checked so far I have mapped over the port (1701) in the router, However when I use the online open port checker tool it cant find the svchost.exe application error windows xp sp3 service. I tested a http file server on that port and it saw my service to the port is not being block by my router. The Firewall is a set to allow the connection over the correct network interface. Edge translation is allowed Any ideas?

From your description, I understand that the error 789: "The L2TP connection attempt failed because the security layer encountered a processing error during initial negotiations with the remote computer" is received when trying VPN from the WAN on a remote computer. This is a generic error which is thrown when the IPSec negotiation fails for L2TP/IPSec connections. Possible causes for this issue could be: a> L2TP based VPN client (or VPN server) is behind NAT. b> Wrong certificate or pre-shared key is set on the VPN server or client c> Machine certificate or trusted root machine certificate is not present on the VPN server. d> Machi

Error 835, Incoming Connection, IPSec, L2TP, NAT traversal, NAT-T, VPN, VPN Server, windows xp pro nce upon a time I wanted to be able to VPN in to my home network. I researched a bit https://rotwhiler.wordpress.com/2009/04/09/windows-xp-pro-as-a-l2tp-ipsec-vpn-server/ and discovered that my Windows XP Pro computer could be set up natively as a VPN server. I followed the built-in wizard, forwarded the appropriate ports on my router, and was up and running. But, https://www.experts-exchange.com/questions/24618511/Windows-Vista-VPN-Client-L2TP-IPsec-VPN-Connection-to-ASA-5510.html the VPN connection only worked with the PPTP protocol and I wanted to be able to use L2TP/IPSec, because of its stronger security. The XP documentation says it supports L2TP, but it's not so easy windows xp to set up, because of lack of documentation, and lack of default support for NAT traversal (apparently, Microsoft thought that this feature was a vulnerability, because they removed it by default in SP2.) This is my most ambitious Technical Bedtime Story yet. The solution took days of googling and experimenting to get just right, but it works (by all means, please let me know if you know of a better way windows xp sp3 to do this). Here's are the steps; I used Windows XP Pro as the VPN server and Windows Vista as the VPN client: Create an Incoming Connection on Windows XP Pro Go to Control Panel/Network Connections Click on Create a New Connection Select "Set up an advanced connection", click Next Select "Accept incoming connections", click Next, Next Select "Allow virtual private connections", click Next Check the user you want to be able to connect, click Next Select "Internet Protocol (TCP/IP)", click Properties Check "Allow callers to access my local area network" Select "Specify TCP/IP addresses" Add two addresses from your local range, click OK, Next, Finish Use Simple Authority to create a computer certificate on Windows XP Pro Download and Install Simple Authority Use Simple Authority to create a Certificate Authority (CA) and then a certificate. (It should put two certificates on your Desktop, with .cer and .p12 extensions) Import the certificate on Windows XP Pro Go to Start/Run Type "mmc", click OK In the window that pops up, click File/AddRemove Snap-in, click Add Select "Certificates", click Add Select "Computer account", click Next Select "Local Computer", click Finish, Close, OK Expand the Certificates folder Right click the Personal folder, then All Tasks/Import, click Next Click Browse and find the cer

Solved Windows Vista VPN Client: L2TP/IPsec VPN Connection to ASA 5510 Posted on 2009-07-31 VPN Windows Vista Cisco 1 Verified Solution 10 Comments 8,644 Views Last Modified: 2012-05-07 I have done extensive research on the internet regarding this subject and I am at my wit's end. I have spent the last few weeks working on configuring a new Cisco ASA 5510 VPN connection utilizing L2TP/IPsec. The entire configuration is in a lab environment and works perfectly. I can login to the VPN and move traffic using my iPhone. The same is true for the clean install Windows XP SP3 laptop that I have for my test environment. The problem comes from the 2 windows vista laptops that myself and the IT Director are using to connect to the VPN. I have an x64 Vista Business SP2 Dell Precision M4400, and my boss has one of the new Latitudes with x86 Vista Business SP1. Neither one of them can connect and immediately receive the following: Error 789 - The L2TP connection attempt failed because the security layer encountered a processing error during initial negotiations with the remote computer. The failure is immediate, so I assumed that it had something to do with IKE. After installing the Microsoft IPSec Diagnostic Tool, and running it for the remote connection to the ASA, it returned the following: IPSec Service Diagnosis - Failed: IKEEXT and PolicyAgent services are not running. Ipsec is inactive. Putting the ASA in debug mode for isakmp and ipsec is to no avail as the failure is before it even reaches the device. I ran services.msc and looked for the IKE and AuthIP (something like that for the name, I can't remember exactly what) and the IPsec PolicyAgent service, and to my surprise, neither one of them exists in my services window at all. After a scan through the registry, I saw that both of these services have a key named ServiceDllUnloadOnStop set to a DWORD value of 1, but many other services have that as well, and many of them are listed in the services.msc window. I have a feeling that this is a Vista issue (maybe even a Dell OEM Version issue), but the folks at Dell didn't know what I was talking about. My next step is to go in on Monday and do a fresh V
